● Communications Parameter Setup
Cable Diagram
The E5CN/AN/EN/GN's communications specifications are set in the
communications setting level. These parameters are set on the E5CN/
AN/EN/GN's front panel. The following table shows the communications
parameters and their setting ranges.

Note: The communications data length for Modbus must be 8 bits.
Before you carry out communications with the E5CN/AN/EN/GN, set up
the communications unit number, baud rate, and other parameters by
carrying out the following procedure. For details on operations other
than communications parameter setup, refer to the E5CN/E5AN/E5EN/
E5GN Digital Temperature Controllers User's Manual Basic Type (Cat.
No. H156) for the devices being used.
