Serial Port Configuration
To set up any of the five serial ports, click on one of the Configure Port X (where X is 0,1,2,3, or 4)
buttons on the main menu. The port configuration menu for port X is seen below (all 5 ports similar).
Choose the desired serial protocol, either Modbus/RTU or CD600. Select the serial baud rate and
character format (parity, stop bits). Parity can be even, odd, or none. You may choose 1 or 2 stop
bits. Set up the serial device address ranges by entering the range low address into the First
Address box and the range high address into the Second Address box. Enter desired device
response timeout into the timeout box. Finally, click on the Submit button to save the new
information.
Notes:
•
For a particular serial port, any and all slave devices connected to it must all be set to the
same parameters that were selected for the serial port.
•
When selecting 2 stop bits for a port, the ENET-710 will ignore the parity setting in the
menu and use no parity.
•
When selecting the CD600 protocol, the parity and number of stop bits settings are ignored
by the ENET-710.
•
The same address range must not be repeated when setting the ENET-710 ports. For
example, there are 20 devices in the configuration. So, the address range for the
Port 0 is from 1 to 20, and for the Port 1 is from 11 to 20.
IMPORTANT
Ports using the same protocol cannot have any repeated addresses.

RS-485 Port Operating Modes
To set up the RS-485 port operating modes, select the Set Channel Operating Modes button on the
main configuration menu. Here a redundant mode configuration for the RS-485 ports can be
enabled. The serial port pairs 1-2 and 3-4 can provide redundant operation in case the connection of
one member of the pair fails. The modes include Independent (no redundancy), Parallel, and Ring.
The menu is shown.
