Checking from Epson RC+ (RS-232C)

When an RS-232C board is installed in the Controller's option unit, the Controller software automatically recognizes the RS-232C board. Therefore, no software configuration is required.

You can confirm on the Epson RC+ screen that the board was correctly recognized.

1. In the Epson RC+ menu, select [Setup] - [System Configuration] to display the [System Configuration] dialog box.
   
   

2. Select [RS232] - [CU].
