Description of operation
Configuration of EY3600 and EY-modulo 2 stations via RS-232 interface. Access unit for SAUT-
ER novaPro visualisation and novaNet OPC-Server management level software.
The novaNet EYZ291F001 router is used to connect the EY3600 novaNet to a (notebook) PC via the
COM interface. The connection is either directly to the PC COM interface or via a dial-up modem as

regards every other switched or unswitched RS232-compatible device pair (ISDN adaptor, line driver,
converter for optical fibres, dedicated line modem, wireless modem etc.). The novaNet router has 1
MB buffer memory for de-coupling the time characteristic of the novaNet and the RS232 interface.
The functionality in the dial-up mode comprises the selection from above (remote access/router
mode) and the selection from below (remote monitoring/routel mode, i.e. automatic reporting of rele-
vant events).

Intended use
This product is only suitable for the purpose intended by the manufacturer, as described in the “De-
scription of operation” section.
All related product documents must also be adhered to. Changing or converting the product is not ad-
missible.

Engineering notes
• The EYZ291F001 novaNet router is designed for mounting on a DIN EN 50022 top-hat rail, as well
as for portable use or as a tabletop device.
• The EYZ291F001 version is powered with 230 V~ and the EYZ291F005 version with 115 V~.
• On the back there are a socket for the mains power supply (3-pin P+N+E lead required) and power
switch, a DB9 plug for the RS-232 connection, 1 DIL switch for selecting router or routel mode, 3
DIL switches for selecting the baud rate (19200, 38400, 57600) as well as an RJ-11 socket and a
plug-in screw terminal for connecting to the novaNet.

Switch 1 = On (switch down) switches the novaNet291 to routel mode.

The baud rate of the COM interface is selected by setting the corresponding DIL switches (38400
baud recommended). If no baud rate switch is set, a speed of 9600 baud is selected.

Disposal
When disposing of the product, observe the currently applicable local laws.

Wiring
Note:
The pin assignment of the RS-232 plug is defined according to DTE (data terminal equipment), which
means crossover cables must be used for connection to a PC (=DTE).
• The crossover should be as shown below.
• Not all null modem cables are suitable.
• A non-crossover cable (supplied with the modem) is used for connection with the modem.

Application
• Clip-on PC: Access to AS network with computers without an ISA slot (notebooks).
• Remote access (router mode): Access from PC to the novaNet via all types of connected or non-
connected networks, by intermediary connection of two DCEs (e.g. modem access via telephone
network or access via ISDN TA, fibreoptic converter, COM server, CATV modem, wireless modem
etc.).
• Remote monitoring (routel mode): Remote units report significant events (configured using no-
vaPro32) via a connected network to a central operating station.
