7-6 Computer link using communication port
The PG/COMM1 and PG/COMM2 ports are built into the JW-3**CU control module as communication
ports for the JW300 series. The EA-PG port is available on the JW-32EA I/O bus expansion adapter. You
use communication ports to communicate with host computers (personal computers, LCD control terminals,
etc.) through the RS-232C/422A I/O ports.
- They can communicate using the same method as the SHARP computer link.
- For wiring details, see section 6-2, "Wiring the communication ports", in this manual.
