2 System description
The DCU5 system is a modular I/O system to control digital and analogue signals. It is designed
for DIN rail mounting at switchboard. It is used during installing of data logger, Voyage Data Re-
corder (VDR), alarm systems but also for controlling motors or lighting applications. The DCU5 is for
capturing signals from various sensors, relays or PWM outputs. Communication can take place via
RS 422 or Ethernet 10/100 Mbps.
TCP/IP, UDP, NMEA 0183, MODBUS RTU or customer-specific solutions are possible. It is tested
according to IEC 60 945 and has the approval of Germanischer Lloyd.
Each system consists of one control unit MCU and at least one module AIM, DIM, DOM etc. The
configuration of the hardware is automatically detected and generates the appropriate NMEA tele-
gram. With parameters the baud rate, the telegram header and the output frequency of the
telegrams can be set.
The configuration and combination of the modules are optional selectable.
At the core of the MCU the 5V power for the connected modules will provided.

DCU5 -Hardware

3 DCU5 -Hardware
The DCU5 is a flexible, modular I/O- system designed for DIN rail mounting.
Each DCU5 consist of one MCU5 and one or more I/O modules. The maximum of modules depends
on the type of the I/O module.
The MCU5 supplies 5V/ 3A and 24 V/1,85A fused to the connected modules
All together 9 modules are possible anyway.
There is no specific order to combine the modules. At the last module in line and only there the EOL –
jumper must be closed! The system recognizes the module automatically at start up and sets itself up
according to the stored configuration data.

Figure 4: Dimensions for MCU5 and all DCU5 modules

The DCU5 system can be delivered with one compact enclosure or with separate casing for each
module as shown in Figure 4: Dimensions for MCU5 and all DCU5 modules.
Anyway the complete unit has to fix on a DIN- rail to give the necessary stability.

DCU5 -Hardware

3.1 MCU5
The Main Control Unit called MCU5 is the base to control the connected modules. The data ex-
change takes place via the X2 connector.
Furthermore, the 5V supply for the AIM10_2 and DOM230_4 modules is provided via the X2 con-
nector. The query is internally approx. 10 ms cycle time per module, so that changes are promptly
recorded on the digital inputs. Only for the duration of sending telegrams, the query is suspended.
The relatively high sampling rate and the event-driven telegram output results in a high probability
of detection of short pulses, as tiller signals to steer.
The closing of a contact input or applying a voltage to the voltage inputs immediately sends the
proprietary edited telegrams that reflect the process image. The output frequency of these tele-
grams is adjustable via parameter and defaults to 1 second. The software also allows the control of
the DOM230_4, AOM12_1 or other output module –using a proprietary NMEA telegram.
Communication takes place via a serial interface of type RS 422/RS 485 or optional via Ethernet
10/100 Mbps at the RJ45 jack. The protocols are described in the section 3.6.

3.2 DIM8

The DIM8 module contains 8 electrically decoupled digital inputs. The inputs can be configured
independently to each other for the input from contacts or 24 DC.
In case of 24V signals the following limits needs to mind:
Logical High: 8 ... 48V
Logical Low: 0...3V.
The galvanic isolation of the channels between them and the system is designed for 1.5 KV. If the
inputs configured to contact query, the operating voltage of the MCU5 is used for self- powering. By
two resistors of 1.3 KΩ the current is limited, so the power supply range from 10-32 V is no prob-
lems with by this setting. For contact input the upper terminals 1,3,5,7... ,15 may be connected to a
common line to save cable wires. The EOL jumper must be set when the module is the last on
the bus otherwise the jumper must remain open!

3.3 AIM12_2
The AIM12_2 provides an A/D conversion of signals with a resolution of 12 bits at two galvanic iso-
lated channels.
Thus, there are two values in the corresponding AIM per telegram. The position corresponds to the
position in the telegram counted from the left (MCU-page). This module becomes compatible to the
older AIM 10_2 if a special soldering jumper is set.
The inputs are operating independently. With the help of jumpers, the voltage input ranges or the
current range can be selected. The galvanic isolation is designed for 1.5 KV. The current inputs are
protected with a self-resetting fuse of 50 mA against overload.
The input impedance of the voltage range is greater than 1 MΩ, so that may be obtained from open
terminals indefinite readings. The output value is only calibrated by software, however, ensures that
no clipping occurs in the specified ranges. For example, the maximum value of 4095 is achieved at
+ 10.2 V. The assignment to the physical quantity, such as the steering angle, speed, etc. will there-
fore be made with the aid of calibration over the entire system in compiling the telegrams from the
DCU software or in its parent system. If the inputs are shorted and no current flows into the input, the
output in the bipolar range is 2047 and 0 in the unipolar range (J3/J6 closed). This corresponds to
the zero point. If the sensors are not linear, relevant tables have identified with supporting values,
and interpolate the intermediate values. This calculation can also be carried out internally by the MCU
with appropriate calibration, so that the numerical values correspond to the nominal values in the
analogue telegram. The EOL jumper must be set when the module is the last on the bus other-
wise the jumper must remain open!

3.4 DOM230_4

The digital output module (DOM) can be connected with 4 relay circuits. There is always a
changer contact on the terminal block available. The maximum loading capacity of contacts is
250VAC/8A or 24VDC/3A. The assignments of values to chapter DCU Control telegrams are
based proprietary NMEA telegrams.
After Power On of the DCU, all bits of the DOM are set (LED = ON). This is also the power-
less status of the relays as given in Table 9 (C-NC contact is closed). From now the software in
the MCU5 controls the behaviour of the contact. A reset by software or the watchdog while the
power is on does not change the actual state of the switches

3.6 DOMOC_8
The Digital Output Module Open Collector 8 (DOMOC_8) contains 8 bipolar transistor switches. They
are galvanic isolated to the System and to each other. The limits for each switch are 60V and 0,75A
DC. The output control byte is of Little Endean type as shown in Table 12: DOMOC_8 connections .
After Power On all bits are set to ‘1’ means the LED’s are bright and the switch is closed.
If one bit is set to ‘0’ the switch will open and the LED will be off.
A reset by software or the watchdog while the power is on does not change the actual state of the
switches.

If an error occurs in the DCU system a corresponding error message about an alarm telegram will be
generated and the ERR LED on the MCU starts lighting as seen in Figure 2: layout MCU, dimensions
for all Modules the same The integrated watchdog reset is triggered and the system reboots.

The I/O data will be managed independently from the module into 4 groups:
1. Digital inputs (DI) on the module types DIM, DIMPT
2. Analogue inputs (AI) on the module types AIM, DIMPT
3. Digital outputs (DO) on the module types DOM230_4, DOMOC_8
4. Analogue outputs (AO) - on the module types AOM12_1

This abstraction from different hardware configurations simplifies the configuration of the system.
The counting method is suitable for all types of data separately, starting from the left (MCU
side) with 0.
The first is the analogue input channel AI0, for example, on the first AIM-module CH0 (X3:1-2)
for the MCU.
The digital inputs are available, depending on the module up to 8 channels on DIM_8.
The analysis of the telegram dependents on the configuration of the DCU.

4.1 NMEA- telegram generation with the DCU5

It is possible to generate NMEA output with the DCU5 according to IEC 61162-1.
Up to 10 different NMEA like RPM, RSA or XDR and 2 types of proprietary NMEA- telegrams can be
defined with the configuration of the DCU5.
T h e generation of NMEA-telegrams needs a DCU5 configuration which provides the required ana-
logue and digital inputs.
For example a $--RSA telegram with 2 rudder information needs 2 analogue input channel to meas-
ure the rudder angel. In this case the DCU should consist of one MCU5 and one AIM12_2 at least.

4.1.1 Generation of proprietary NMEA

Telegram structure of the proprietary telegrams is:

$[PHEADER][TYPE],fn,X1,…,Xn*[LRC]<CR><LF>
Only the Header and the frequency of the transmission can be modified by setup. All other parame-
ters are predefined by the hardware configuration.

 Software

Description Example
PHEADER Address field, max 8 capital characters PV00
TYPE Specification of the data X1-Xn DI, AI ,DO, AO
F Number of telegram in a group 0...9
N Number of data fields 1...8
X1... Xn Data field
LRC LRC Checksum according IEC61162-1
CR, LF Limiter of the telegram 0x0D0x0A

Table 15: Fields in proprietary NMEA

When programming the telegram header the IEC 61162-1 should be respected! The maximum frame
length of 82 characters is limited by the software itself.

If more than 8 data fields are necessary to form a telegram ‘f’ increments and a second telegram will
be generated.

Example: The DCU contains 6 x AIM12_2 = 12 values so 2 telegrams are necessary.

1. PV00AI,08,X1,X2,X3,X4,X5,X6,X7,X8*[LRC]<CR><LF>

2. PV00AI,14,X9,X10,X11,X12*[LRC]<CR><LF>

 1x DOMOC_8 : $PV00DO,1,FF*0C ; all 8 LED are on
 4x DOM230_4 : $PV00DO,2,0F,A5*0C ; LED pattern: 0000 1111 1010 0101

AO This type gives the current value of all analogue outputs in the system as digits (0...4095).

If the DCU receives a control telegram to set the digital or analogue outputs, proprietary telegrams of
the type DO or AO responds from the DCU as the result.
If the parameter DOTIME and AOTIME is different from 0 the telegrams will be repeated within these
times.

4.1.2 Generation of standard NMEA

These types NMEA- telegrams are formed with help of NMEA Format Strings in the following called
NFS.
The general format of the NFS is [field 1],[field 2],....[field n][CR][LF].
The fields are separated by commas and the string is limited by 0x0D0x0A (Enter) like NMEA sen-
tences. All characters of the NFS will print out as given excepted from the ‘~’ marked special fields.
That means the NFS is the expected NMEA with special fields in place of the variable outputs.

If the first character in the field is ‘~’ (0x7E) the following data of this field describe the input source
which generates the printout in the NMEA.

The general structure of such a field is: ~[type][channel no.]; [parameter1];[parameter2];[parameter3],

If parameter1 is missing the actual calibration table for the analogue channels is used to
assign real values to the measured digits! The online calibration will give more exact-
ness! Further details are given on chapter 5.
Effective range: The AIM12_2 modules have 2 basic effective ranges selectable by jumpers. See
also Table 7: AIM12_ range adjustment. These basic ranges include parameter ranges selectable
with help of the parameter1.

Software

Example with all three parameter:

The NFS “$IIRSA,~A0;1;-35;35,~?;A;V,,” generates NMEA telegrams according Table 19.

The necessary conditions are:

1. The exactness of 1% of full scale is enough for the application.

2. The jumpers of AIM12_2 are set for +-10V.

3. The rudder sensor provides – 10 V @ -35° and +10V @ 35°

The digits of set point 2 and 4 are set by the statistic mean value of digits for -10 V and 10V.

Example without parameter:

The NFS “$IIRSA,~A0,~?;A;V,,” generates NMEA telegrams according Table 19.

Set point AI[0] Calibrated set point NMEA Output

1 4095 35 ( theoretical maximum) $IIRSA,35.0,V,,*0E

2 4085 35 ( real maximum) $IIRSA,35.0,A,,*0E

3 2047 0 (real zero) $IIRSA,0.0,A,,*2F

4 15 -35 (real minimum) $IIRSA,-35.0,A,,*23

5 0 -35 (theoretical minimum) $IIRSA,-35.0,V,,*23

Table 19: Example calibration table for RSA

The value of 4085 represents a electrical value of 10V or 20 mA or a rudder angle of 35° (SB). If the
voltage rises over this limit the measurement becomes invalid. The same happens at 15 digits which
may represent -10V or 4 mA or – 35°( PS). See also Table 7: AIM12_ range adjustment and section
5.1 Configuration of the MCU5.

4.2 Control of output channels

The DCU5 system may be configured with analogue and digital output modules.
These modules can be used to convert values given by NMEA – sentences into analogue or digital
outputs like contacts, voltage or current signals.
For example it is possible to control an analogue rudder indicator with the help of an RSA- telegram.
Also wind speed or other limit switches with relay outputs are possible.
A timeout function can be enabled to watch the NMEA inputs on the serial line.

4.2.1 Proprietary NMEA to control DCU5 outputs

The general format of a proprietary NMEA to control DCU outputs is:

$[PHEADER][TYPE],X[0],…,X[n]*[LRC]<CR><LF>
Description Example
PHEADER Address field, max. 8 capital characters, PV00
can be changed in the DCU5 –setup (See
section 5.2.4)
TYPE Specification of the data X0-Xn OD,OA
X[0]... X[n] Data fields
LRC LRC Checksum according IEC61162-1
CR, LF Limiter of the telegram 0x0D0x0A

Table 20: Fields in proprietary control NMEA

Type Importance of data X[0]... X[n]

OD X[n]= address of digital output channel: range 0...max. number of digital output channels
X[n+1]= State to set this output channel : range 0= LED OFF or 1= LED ON
Example: DCU5 with 2xDOM230_4:

 NMEA send to the DCU5: $PV00OD,0,0,3,1,7,1<CR><LF>; LRC can be omitted .

 Result on the Relays: 1. DOM K1 =0,K4=1: 2.DOM K4=1, all others relays will not change.
 The response telegram depends from the other state and has a general form of:
 $PV00DO,1,xx*[LRC]<CR><LF>.

OA X[n]= address of analogue output channel: range 0...max. number of analogue output channels
X[n+1]= value to set this output channel: range 0...4095 (12 bit ) or 0...1023 ( 10bit)
Example:DCU5 with 5x AOM12_1:
NMEA send to DCU5: $PV00OA,0,0,1,2047,4,128<CR><LF>

 The response : $PV00AO,5,0,2047,x,x,128*[LRC]<CR><LF>

x = unchanged value of the other channels

Table 21: DCU output control types

4.2.2 Standard NMEA to control DCU5 outputs

It is possible to control DCU5 outputs with NMEA according IEC 61 162-1.The received NMEA is ex-
amined for the start symbol ‘$’, valid characters and LF (0x0A) at least on the 82’th character. If the
LRC checksum *hh is present this is being examined. All received NMEA messages are send un-
changed. Only if the syntax check is successful, the NMEA- string will be checked with all pro-

29
Software

grammed Output Control Strings (OCS). Each DCU5 – Output channel has his own OCS. If more
than one value in the NMEA should be converted you need one OCS for each value!
If a Set Timeout > 0 is programmed the serial input line is monitored for received telegrams within this
time gap. In case of timeout all outputs of the DCU are set to 0!! It means all digital outputs become
ON and all analogue Outputs will be set to 0 digits!
This behaviour may be suppressed with setting 0 to the Set Timeout parameter.
General structure of such a OCS is:
[HEADER],[POS],[STATUS],[DCU-Output],[Para.1],[Para.2],[Para.3]<CR><LF>
Each OCS consists of 7 fields (field 0... field 6) separated by commas.

No Field Description

0 HEADER -Up to 10 capital letters, it will be compared with field 0 of the NMEA telegram.
-Wildcards ‘?’ are possible.
1 POS -Number of the field in the received NMEA which contains the control string .
2 STATUS Position of the field with the valid status,
A Null field (“,,”) is used if no status is available or the status should be omitted.
3 DCU-Output Type and number, counted from MCU to right, D0..Dn or A0... An
Type D - digital output Type A- analogue output
4 PARA.1 LIMIT_ON or the text which has to Minimum of the control value
match with the string at POS
5 PARA.2 LIMIT_OFF Maximum of the control value
PARA.3 Position of unit for the speed value
conversion; 0 if no conversion is re-
quired
CRLF Return Line feed ( 0x0D0x0A)
Table 22: OCS-structure

Examples OCS with wildcards:

If OCS $??MWV,3,5,D0,10,6,0 is set all MWV- NMEA telegrams will be used.
If OCS $??HD?,1,,A0,0,360 is set all HDT- telegrams and HDG-telegrams will be used to convert e.g.
360° to 0-10V.

The Limit parameter must have the following units:

Speed : m/s
Distance: m
Select if possible the NMEA- POS for values in m or m/s to avoid conversion time.
Example: $SDDBT,3,,...,0 ; The third position holds the depth in m.
General procedure:

 Compare NMEA- Header with OCS header.

 Read the string at POS from the received NMEA
 Compared it with PARA.1 and PARA.2
 Set the DCU- output accordingly.

30
Software

The meaning of the Parameter1 and 2 is determined by type of the DCU output.

1. Type D - Digital Output

If PARA1 starts with 0..9 or ‘+’ or ‘-‘
 PARA1 is the LIMIT_ON threshold. The speed unit is m/s.
 PARA2 is the LIMIT_OFF threshold. The speed unit is m/s.
 PARA3 is the position of the unit for conversion of the speed value before compare with
the Limits. If PARA3 is 0 no conversation will carry out.
 The value reads from POS is compared with the LIMITS
 The digital output is switch ON if value exceeds LIMIT_ON
 The digital output is switch OFF if value falls short of LIMIT_OFF
else the PARA1 is considered as a text
 This text will be compared with the received text at POS .
 The digital output is switch OFF if this compare becomes true.
 The digital output is switch ON if this compare result is false.

 PARA2, PARA3 doesn’t care in this case.

2. Type A - Analogue Output

 PARA1 is the expected value at POS to be assigned to the digital minimum of 0.
 PARA2 is the expected value at POS to be assigned to the digital maximum of 4095.
 PARA3 is the position of valid field referring to the analogue value.
 The analogue output is set with respect of the given range
 Input values outside of the designed range don’t change the output value.
 The real physical output, voltage or current, must be set by jumpers at the AOM12_1
module

Example 1:
An alarm should be active if the wind speed exceeds 10m/s and should be inactive if the wind speed
falls below 6m/s.
The DCU5 consists of one MCU5 and one DOM230_4.
The alarm contact D0 is X3:1- 2 at the DOM230_4, see also Figure 7: DOM230_4 Layout
The wind speed is given in the NMEA telegram $WIMWV at position 3 and the speed unit in position 4

The resulting OCS is: $WIMWV,3,5,D0,10,6,0

How to setup this OCS please look to section 5.2.7.

Software

Example 2 :
A rudder indicator with a range of +- 45° @ +- 10V should be controlled by $IIRSA,x.x,a,,,
The internal resistance of the indicator electronic must be more than 1 KOhm!

The DCU5 consists of a MCU5 and one AOM12_1 (A0) with a +- 10 V selection.
The necessary OSC for the starboard rudder sensor is: $IIRSA,1,2,A0,-45,+45,0
The output channel A0 is the first analogue output in this DCU5 system.
The rudder angel is read from field 1 in the RSA telegram (SB or single rudder)
The minimum should be – 45° and the maximum 45°.
Field 2 is the valid status. If there is a ‘V’ the NMEA- input is skipped from output control!
The resulting voltage or current output is determined by the jumper of the AOM12_1.
See also Figure 10: AOM12_1 layout!
If a second analogue output channel (2x AOM12_1) is available the port rudder sensor value can be
used to control this output.
The necessary OSC for the port rudder sensor is: $IIRSA,3,4,A1,-45,+45,0

5 Installation and set to work

Prior to the removal of the modules from the package a sufficient ESD protection have to be re-
spected. Minimum is to create a grounding strap and the same potential between packaging and
the mounting strap. Contact with the bus connector should be avoided. The modules are mounted
or dismantle only in the energized condition

On the last module (far right) and only on this module, the EOL jumper is to set. The modules are
mounted on a DIN rail TS 35 and stick to each other. The correct fit between plug and socket of the
bus is observed. The system is to fix with suitable end braces left and right. Before connecting the
analogue and digital signal sources whose voltage range is to check with a voltmeter! The permis-
sible operating voltage is 24 V (12 - 32V). The digital inputs are strain resistant up to 48 V.

The analogue inputs are strain resistant up to +/- 30 VDC. In the current input a self-resetting
fuse is installed, which protects the internal shunt, and after breaking the circuit even roll back.

For the connection of 110VAC up to 230VAC VEINLAND delivers suitable ballast module of type
VSM230AC. Are contact inputs configured, the operating voltage of the DCU is fed through a re-
sistor of 2.7 KΩ. There should be no external voltage applied from external. If voltage inputs are
configured, “+” terminals are on the upper row (odd numbers) and the “-“ terminal on the bottom
row (even numbers). Contact inputs and voltage inputs are freely mixable on each module and
are to the system and with each other electrically isolated.
Grounding of the module
The system should be connected via shielded cables to the signal sources. Here, the screen is
one-sided, centrally located near the MCU on the hull (GND). The guard ports of the
MCU and the AIM modules are also grounded at this point. All signal lines, especially the ana-
logue one are as short as possible, leading to the terminals of the modules and hang up.

5.1 Configuration of the MCU5

For configuration the transparent cover has to be removed. It turns out the circuit board according
to Figure 1. By briefly closing the jumper RES a start up menu via the RS422 and the Ethernet
is issued. The output is always done regardless of the programmed baud rate at
4800 8N1. If the programmed baud rate is unknown, it can be read at the start up of the RS-
422 with 4800 8N1, the parameters before surrounded the MCU to the programmed baud
rate.
The baud rate of the Ethernet converter and the microcontroller must be adjusted separately and
must be equal to the programmed baud rate of the MCU! The settings of the XPort- Ethernet con-
verter have to be made by a web browser.
The factory setting of the network connection is TCP/IP, IP = 192.168.1.151 and local port 10001.
The baud rate is preset to 4800 8 N 1 for RS-422 and the converter.
The Telegram output can be adjusted by using parameters. The parameters can be stored and re-
loaded with help of the terminal program OC-Console.

The connection between RS 422 and RS232 is non standard and may cause failures! It is recom-
mended to use a suitable converter for the PC- port. Alternatively, the parameter input can also be
done via the network.

5.1.2 First start up

 Connect X1 with a PC (COM - port) according Table 23: Serial connection DCU5- PC
 Start a terminal program like “OC Console” etc.
 Configure “OC Console“ as shown in Figure 13: Terminal setup .
Switch Power on or short “RES” for app. 1 second if the power is already on.
At first the actual software version is print out. The modules check follows and gives the actual con-
figuration of the DCU- IO system.
The splash screen is always transmitted with 4800 8 N1 up to the printout “Serial line runs...”. Thus,
regardless of the set baud rate, the parameters can be determined and, if applicable, the baud rate of
the terminal program may be adjusted.
The actual setup- parameters are shown until the printout “---------- Running-----------“.
The output of NMEA – telegrams is controlled by parameter and the hardware configuration.
So the repeat time for the telegram type must not be set zero and the input module (DIM8,AIM12_2...)
should be listed in the start up screen.

5.2.3 I/O configuration

The configuration of the analogue channels is necessary for the generation of standard NMEA- tele-
grams.
In general it is an assignment of physical values to the measured digits.
The software calculates with help of a calibration list.
This list contains 11 pairs of digital values and the assigned set point like rudder angel, rpm and so
on.
Before starting the calibration it is necessary to set the range of the analogue input. See also Figure 6

38
Installation and set to work

Figure 18: I/O- configuration

The decimal places in the print out is selected by a code 0..6. For NMEA sentences mostly one deci-
mal place is needed. Therefore code 1 should be selected.
Figure 18 shows the calibration table with the default settings. It consists only of 2 set points and
would result a print out of 10.0 at a measurement of 4095 digits. But the AIM12_2 delivers 4095 at
app. 10.2 V! Therefore a further calibration is recommended to get the correct result.
The next steps give an example to generate an print out range -35 ...35 at a voltage range from -10 V
to 10 V.
It can be used to prepare this analogue channel 0 to use it for RSA – NMEA

The result of the new minimum and maximum is permanently displayed in the bottom line of Figure
19.If the value of s differs from 0 the measurement is invalid. Two additional set points are required
for valid measurements.
The best result will achieve if the real voltage (±10 V) or the real rudder angel (± 35) are applied to the
input.
Then press ‘s’ if exactly 10V or 35° are present on the terminals of the channel and type this set point
in. Figure 20 shows the procedure. It should be done also for -10V or -35° in the same way. The
manually input is also possible if a suitable calibration list exists.
The item ‘l’ displays the actual calibration list. It is useful to give a overview and for documentation
purpose. In Figure 21 is the calibration list for AI0 displayed. The calibration may finished with ESC.

5.2.4 Proprietary NMEA

The structure of the proprietary NMEA telegrams is fixed. The repeat time of the telegrams can be
adjusted within the possible range. If it is set to zero the output is disabled. Unattached of that a AO-
or DO – type will be send if a proprietary setting telegram ( OA,OD- types ) was received before.

5.2.5 Approved NMEA telegrams according to IEC 61162

In this group of NMEA telegrams describes for e.g. by RSA, RPM, XDR or others in which analog or
digital input signals are used. Please see section 4.1.2 for more information

These predefined NMEA messages can be generated with the help of so-called NMEA Format
Strings. These NFS represent the desired NMEA telegram with special fields for the dynamic input
values.
In the variable fields, for example where it appears analog measurements are special scripts to gen-
erate the wording of the present position of the NMEA telegram. The checksum is automatically calcu-
lated and added at the end.
The general structure of a NFS is: <Field0>,<Field1>,<Field 2>….<CR><LF>
The total length of the one NFS is limited to 128 bytes. The resulting NMEA specifications must meet
the IEC 61162 standards. A review of the generated NMEA telegrams through the software will take
place only on according to the length. Over lengths are then cut off easily!
The scripts are connected with the analog or digital inputs, start with a reserved character, the tilde (~
= 0x7E) then follow an input channel number and type with 3 parameters that are defined in Table 3
below. The parameters within this field are separated with a semicolon (;). There the comma is the
separator of the fields and the fields to the next field. If in the script is the last field before the check-
sum then no comma is set accordingly, here before * ' in NMEA, no comma will be set.

The results of testing of the analog measurement are based on the fact that the inputs have an over
ranges. In the calibration of the respective channels of the measuring range is associated with two AD
readings. Table 25 shows the relationships and the impact on the NMEA output, which are generated
with $IIRSA,~A0,~?;A;V,,.

3 38 -35 (Real Minimum) $IIRSA,-35.0,A,,*23
4 0 -35 (Theoretical Minimum) $IIRSA,-35.0,V,,*23 (invalid)

Table 24: Example of the calibrated table

Calibration points for the + 10V,- 10V, 0 mA, 4mA und 20 mA are set from the factory. However, it is
also possible to omit the analog parameters 1-3 (~ A0, ...). Then the output is controlled according to
the stored calibration table. It's always useful when non-linear sensors must be adjusted, or the sen-
sors which possess no standardized interface such as 4 - 20mA.

5.2.6 Summary

It is important that the setting of the measuring ranges fits together on the board with the calibration.
If the measuring ranges of jumper changed, the change in the calibration is also required. This must
be done through the new NFS!

5.2.7 Output Control String

Please see section 4.2 Control of output channels for more information
DCU 5 outputs can be controlled by special NMEA sentences.
Up to 10 Output Control String (OCS) can be defined.
Figure 23: Configure Output Control String shows the way to generate a wind speed alarm which
becomes active above 10 m/s and switches off if the wind speed falls below 6 m/s.

5.2.8 Save parameter

It is possible to store all parameter in a file with help of the terminal program.
For OC-Console the procedure is as follow:
1. Open a “Logfile”:

3. Close the Logfile

Figure 26: Open the file with "YES"

4. Open the Logfile and remove all recordings ahead and towards of the parameter data. The pa-
rameter data starts with “;B,(Baud rate.... and ends with “#<CR><LF>!

Figure 28: Remove the marked parts from the file

The parameter ends in the line below the’#’!!

The download function of OC Console contretemps insert spaces (0x20) to fill the line and then it
ends with <CR><LF>.
These “spaces” must remove from the parameter file! Other terminal programs like “Hyperterminal” do
not so and may be better for parameter download. But Hyperterminal must have a delay of 200 ms
after sending a line because there is no handshake character ‘*’ possible. Anyway it is easy to remove
spaces with the text editor by replace each space with nothing.

Figure 29: Replace of all spaces with nothing

Then the corrected file can be saved for later download to the DCU5.

5.2.9 Load parameter

With this function it is possible to setup the complete parameter within some seconds.
It can be used to have identical settings in a series of units. Also it is possible to edit the file before
download. You can change the parameter offline in the office and save time while installation.
Please keep in mind that the analogue parameter of the AIM- modules may depend from the sensors
on board and must be finally checked!
Attention!!
There is no check of the received data while the download is running. If the content or the syntax is
wrong it will be saved as received!!
Be sure that the download settings are made according Figure 13: Terminal setup.

Start the Download of parameter with key ‘L’!

After each received record the setup sends a handshake character ‘*’ = 0x42 to the terminal.
There is an internal timeout in the OC-Console download which breaks the download if the hand-
shake is missing for a certain time.

5.2.10 Reset all Parameter to default settings

Press ‘R’ to init all parameter to default. The system restarts automatically.

5.2.11 Set Date and Time

The MCU5 contains a RTC-unit for generating date and time stamps in NMEA like ZDA or ALR.
Be sure that the 3V battery at the bottom side of the MCU5 is OK ! If this battery is missing or low the
sage “$UPALR,,4,A,V,Init RTC” appears every time when power is switches on.

Figure 34: Setting Date and Time

5.3 Network Setup

The network connection is optional and takes place via the RJ 45 connector X4 of the "XPORT". This
is a "Serial to Ethernet Converter" by Lantronix. This is a standalone component assembly variant. All
serial frames are tunnelled over TCP or UDP, for example, can be sent or received by HyperTerminal
from Windows XP. Technical details are shown below www.lantronix.com. There are all parameters,
IP addresses and protocols through a web interface (browser) adjustable. It is important that the
baud rate matches the serial side of the XPORT with a baud rate of the RS 422 interface. All the
transmitted signals are simultaneously output from the MCU XPORT and the RS 422. For instance,
one of the channels can serve as a monitor on the fly.

54
Installation and set to work

The configuration can be done by Internet Explorer with IP: 192.168.1.151. In the factory default set-
ting is no password assigned, and the screen shown in Figure 35 can confirmed with OK. About Fig-
ure 36 it then passes to the other settings.

6 Service and trouble shooting

6.1 Power LED Z8 is off

The power supply connection should be checked with respect of the MCU version. Please see Table
2: MCU5.6.3 X1 –pin out.
This LED indicates the 5V voltage. The internal 5V regulator has an overload protection.
Disconnect all modules to exclude external short circuits on the 5V line.

6.2 System OK LED Z11 is off.

The internal System check has failed.
If the LED Z2 gives a signal have a look to the serial alarm output with the terminal program. The EOL
jumper must set on the last module on the bus line. It is the last module opposite to the MCU5.
No other EOL-jumper should set on the DCU5 because the software checks for modules until the first
EOL-jumper was found.

Service and trouble shooting

Figure 38: RTC error screen

If the 3V battery of the MCU5 is empty a print out $UPALR,,4,A,V,Init RTC happens every time when
the power turns on. If other error codes as ‘4’ are sent out the MCU5 needs to exchange and repair by
the manufacturer.

6.3 RX- LED Z1 is permanent on

Check cabling according Table 23: Serial connection DCU5- PC

6.4 Unreadable serial output

If the TX-LED Z2 flickers the DCU5 sends data at least while the software starts up.
- Check cabling according Table 23: Serial connection DCU5- PC.
- Check baud rate of the terminal program. It should be 4800 8 N 1 while the DCU5 starts up.

6.5 Wrong or missing NMEA Outputs

See section 4.1 NMEA- telegram generation with the DCU5 and the setup.
