Wire Your Communication
Ports The locations of the module’s communication ports, PRT1, PRT2, and
DH485, are shown in Figure 3.8.
Figure 3.8 Communication Ports
Wire to Ports PRT1 and
PRT2 Ports PRT1 and PRT2 can communicate to user devices through
RS-232/423, RS-422, and RS-485 communication modes. Set jumpers
JW1 and JW2 to reflect the communication mode you desire.
The table on page 3-10 lists the pin assignments for ports PRT1 and
PRT2.
Refer to the MODE command in the BASIC Language Reference
Manual, publication 1746-RM001, for the default programming port
configuration information.
Use these pin assignments to wire the mating connector of the cable
used to interface a user device to port PRT1. The sockets of this
connector must be wired to correspond to the selected
communication mode.
