ROC800-Series Instruction Manual
5-4 Communications Revised July-2017
Note
:
With the exception of the HART module, you can install
communication modules
only in slots 1, 2, or 3 of the ROC800.
Refer to Figure 5-1 and Table 5-1 .
1. Remove the wire channel cover.
Note
:
Leaving the wire channel cover in place can prevent the
module from correctly connecting to the socket on the
backplane.
2.
Perform one of the following:

If there is a module currently in the slot, unscrew the captive
screws and remove that module (refer to
Removing a
Communication Module ).

If the slot is currently empty, remove the module cover.
3. Insert the new module through the module slot on the front of the
ROC800 or EXP housing. Make sure the label on the front of the
module is facing right side up. Gently slide the module in place until
it contacts properly with the connectors on the backplane.
Note
:
If the module stops and will not go any further, do not force
the module. Remove the module and see if the pins are bent.
If so, gently straighten the pins and re-insert the module. The
back of the module
must connect fully with the connectors
on the backplane.
4.
Gently press the module into its mating connectors on the backplane
until the connectors firmly seat.
5. Tighten the retaining captive screws on the front of the module.
6.
Wire the module (refer to Wiring Communication Modules ).
Note
:
All modules have removable terminal blocks for convenient
wiring and servicing. Twisted-pair cable is recommended for
I/O signal wiring. The removable terminal blocks accept 12
to 22 AWG wire.
7.
For dial-up modem communication, connect the cable to the RJ-11
connector on the communication module.
Note
:
If you are installing a modem module, it is recommended
that you install a surge protector between the RJ-11 jack and
the outside line.
8. Replace the wire channel cover.
