Usage of the RS-485 port and the RS-232C port can differ according to the ON/OFF condition at the dip switch 4 set-

ON setting: Using port changeover takes place according to the CD signal of the RS-232C.
• Usage enabled on the RS-485 port when CD=OFF (including no connection).
• Usage enabled on the RS-232C port when CD=ON.
OFF setting: RS-232C only can be used (fixed).
Note
The data port wiring can be changed over between “straight” and
“crossover” by making ON/OFF switching at the No.3 dip switch set-
ting.
