cable entry point. Then, close and secure the door to the

Connecting through the RS-232 Port
When supporting an RS-232 Modbus connection to customer
equipment, such as an RTU or PLC, create a custom cable or use a
customer-supplied serial cable with a DB-9 connector configured to
an RS-232 straight connection specification. A null-modem is not
necessary.
Connect the cable to the ExPAC in the following way:
1. (applicable only when the ExPAC is housed within an XBUS or
other enclosure) Open the door of the enclosure, and run the
cable through the appropriate entry point into the enclosure.
For an XBUS, this entry point will be the left cable gland at the
bottom of the enclosure. You may need to loosen the plastic
nut on the cable gland on the outside of the XBUS or other
enclosure to feed the cable through. If you are using a pre-
fabricated cable, you may need to remove the DB-9 connector
from the cable so that you can feed the cable through the cable
gland or other entry point.
