Setting the Front Panel Switches
Set the unit number of the Serial Communications Unit with the rotary switches on the front
of the Unit. Use a flat-blade screwdriver to set the numerals and symbols of the switch's set-
ting display window, as follows:
Unit number setting
Set a value between 0 and F that is different from
that of any other Units in the system.
Connecting to CJ-series Serial Communications Units
CJ-series Units:
CJ1W-SCU41 (Port 1 is an RS-422A port and Port 2 is an RS-232C port.)
CJ1W-SCU31 (Both ports 1 and 2 are RS-422A ports.)
CPU Unit DM Area Settings
Write the settings directly from the Programming Device (Programming Console or CX-
Programmer) to the DM Area (Parameter Area) in the CPU Unit. After writing the settings,
enable the settings by turning ON the power again, restarting the Unit, restarting the com-
munications port, or executing the CHANGE SERIAL PORT SETUP (STUP) instruction.
The following table shows the allocated DM Area words and settings.
The allocations and settings are the same for RS-232C and RS-422A.
