Make the PLC settings.
Use the CX-Programmer to make the communications port settings for the
Serial Communications Unit. The settings can be easily made using IO Ta-
ble and Unit Setup. Be sure to transfer the settings to the PLC.

(2) When using a communications port on the CPU Unit, start the CX-Pro-
grammer and set the Host Link port settings in the PLC Settings as fol-
lows: Mode: NT Link (1: N), Baud rate: 115,200. Be sure to transfer the
settings to the PLC.
(3) The same serial port on the CS/CJ-series Serial Communications Board/
Unit cannot be connected to both the EJ1 and an NS-series Programma-
ble Terminal.
The following settings are also required if the models listed below are used.
Note
The port 2 terminating resistance switch and 2/4-wire switch are on the bot-
tom of the Unit.

Set the EJ1 parameters.
No particular EJ1 parameter settings are required when using SYSMAC
CS/CJ-series PLCs. Leave the parameters set to their default settings.
When using RS-232C communications, turn ON pin 8 of SW2 to select RS-
232C communications.
For the default settings, the EJ1 monitor and set values are allocated in the
DM Area in the PLC as shown in the following table.
