bus expansion adapter has an EA-PG port.
- JW-311CU/312CU do not have PG/COMM 2 port.
- Please note that the EA-PG port (JW-32EA) cannot be used for "RS-232C" communication and does
not offer a data transfer speed of 230,400 bps. => See page 7-30.
- For operational method of communication port, see page 7-29, "Computer link using communication
