232 pin/signal definition for a V74 or V75 port to have pin 2 configured
for DCD "OUT" you must change the location of JP5 for port 4, JP7 for
port 3, JP9 for port 2, or JP11 for port 1.
1. V75 (See Figure 29)---Install the two position jumper so
that it connects the center pin and the pin farthest away from the
RJ-45 port. Do not move the other jumpers.
2. V74 (See Figure 30)---Install the two position jumper so
that it connects the center pin and the center pin and the pin located
on the left of the common pin with the RJ-45 connectors facing you.
Do not move the other jumpers. In this application use BayTech
adapter, part number 25FRJ45PC-3 or 9FRJ45PC-3.
IMPORTANT: If the module is installed in the base unit chassis,
remove power from the unit by positioning the On/Off switch to "0"
(off) and unplugging the power cord from the AC outlet. Remove the
module by unscrewing the two screws securing it to the back panel
and pulling the module out.
