1.2 Features

* Quick response to weight changes.

* Resolution : Display Resolution: variable
: Internal Resolution : 1/150,000.
* Low power consumption : Rechargeable Battery backup for 60 hours (Backlight Off) 7
hours (Backlight On) of continuous usage .
* Intelligent power control
A. When AC power is available, scale will use AC power only whatever
rechargeable battery is installed or not. When AC power is shut off, scale will use battery
automatically.
B. When scale works on rechargeable battery, if the battery is weak, the battery
indictor will light up. When the power from battery becomes low such that the scale cannot
compute accurately, all Displays will shut off except the Battery indicator. The power is
then shut off completely after 1 minute.
C. Scale detects rechargeable battery voltage and control battery charge process
automatically. The battery charge indicator lights up when rechargeable battery is being
charged.
* Calibration by software.
* 6 digits with 8 segments large size LCD Operator displays with backlight. (figure size:
23×10.9 mm).
* 5 operational keys :UP, LEFT, TARE, ZERO, ON/OFF;
* Waterproof keyboard and splash proof housing.
* Plastic housing.
* One scale channels for remote weighing platforms connection .(14 pin Am phenol)
* Support 4x load cells 350 Ohm.
* Two set point(Hi/OK/Low)
* RS-232C interface for data communication .
* External Remote Display.

*Note: If the additional parity is 0x0d, 0x0a or 0x00, it will be changed to 0x1d, 0x1a or 0x10 respectively.
If it’s in the type A with high speed, the data should be less than 30 bytes.

Status Flag:
Not Fixed Not used Price Price Total Price Net Additional
Used to 1 Base Base Overflow Parity
Bit 7 : Not used. Always 0;.
Bit 6 : Fixed to 1.
Bit 5 : Not used.
Bit 4 and Bit 3 : Price Base. 00 - $/kg, 01 - $/100g, 10 - $/1b, 11 - $/1/41b.
Bit 2 : Total Price Overflow. Set to 1 when total price overflow, 0 when not.
Bit 1 : Net. Set to 1 When tare subtraction is performed, 0 when not.
Bit 0 : Additional parity flag. Set to 1 when additional parity code is added in text, 0 when not.

Weight Condition Flag:

Not Fixed Not Weight Weight Negative Weight Zero
used to 1 used UF OF Net Weight Stable Sign
Bit 7 : Not used. Always set 0.
Bit 6 : Fixed to 1.
Bit 5 : Not used.
Bit 4 : Weight UF. Set to 1 when weight underflow, 0 when not.
Bit 3 : Weight OF. Set to 1 when weight overflow, 0 when not.

21
 Bit 2 : Negative Net Weight. Set to 1 when net weight is negative, 0 when not.
Bit 1 : Weight Stable. Set to 1 when weight is stable. 0 when not.
Bit 0 : Zero Sign. Set to 1 when weight zero sign is set. 0 when not.

Example1: Transmit all data.( Without additional parity)

Net weight = 3.456 Tare weight = 1.200 Weight status : stable
Scale No. = 100 Weight Unit = kg
Status Flag: 0x42

Weight Condition Flag: 0x42

By ASCII Code:
0x42 0x42 0x42 0x0d 0x56 0x31 0x30 0x30 0x0d

0x30 0x30 0x30 0x33 0x2e 0x34 0x35 0x36 0x6b

0x67 0x0d 0x34 0x30 0x30 0x31 0x2e 0x32 0x30

0x30 0x6b 0x67 0x0d 0x0a

Example2: Only transmit Net weight.(without Header Code)

Net weight = 3.456
0x30 0x30 0x33 0x2e 0x34 0x35 0x36 0x0d 0x0a

Note: You had to set some SPECs to satisfy this condition.

Example3: When net weight is overflow, the data of weight will become as follows.
Net weight : OF
0x20 0x20 0x20 0x20 0x20 0x4f 0x46

6.5 Communication Method

Note: Communication depends on SPEC5

The data communication method can be selected from Stream (continuous), Manual,
Command and etc. by specification settings.

When the version=1.13, choose the spec5=0001 (Continuous

output), and set the spec1-bit0=0, you also need set the

spec6-bit1=0, or it will has the problem.

23
6.5.1 Type A (Standard Stream)

Data is transmitted to PC side continuously.

PC SIDE DI-166

Note: Weight stable check depends on SPEC setting.

24
6.5.2 Type W (Standard Manual)

Data is output by pressing Manual key(+ key). User may select to transmit the data right away or
hold the command until weight become stable by specification setting.
PC SIDE DI-166

Note: Weight stable check depends on SPEC setting.

25
 6.5.3 Type B (Standard Command)

The data transmission starts by receiving the command from external (Ex. PC side).

PC SIDE DI-166

Note: Weight stable check depends on SPEC setting.
