When using the 9 pin port, select SYSMAC WAY for Network Type. Settings must match. Default settings are 9600, 7, E, 2.

So, let's see if I can help. To communicate with a CJ1M through the rs232 port, 9-pin port, you must configure the type of plc, the type of cpu corresponding to your hardware, then you must choose sysmac-way in the network type tab, in settings, right next to the network tab type, you must choose the port you are using, for example, if you use a usb-rs232 adapter like me you must say what port it is and / or if you use a usb-rs232 cable you should choose usb.
Hope this helps. I could send some printscreen but I don't know why I can't, sorry.

Dear All,

Currently, all DIP switches are OFF. If I turn DIP Switch # 5 ON, should I restart the PLC or not needed?

Some says SYSMAC protocol should be selected and some says Toolbus, I am not sure which one is correct

I don't think so but if you can manage it, please try.

The Peripheral Port is Toolbus. The RS232C Port is Host Link (SYSMAC WAY). These are default settings. Both ports can be configured differently in software but with limitations.

DIP Switch #5 (ON) will force the RS232C Port to be SYSMAC WAY, 9600, 7, E, 2.
