cause electric shock and may result in
severe personal injury or death.

Mounting

Mounting the RS-232 Card onto the FX
Supervisory Controllers

Mount the RS-232 card in either of the option
card slots on the FX Supervisory Controllers,
as available.

To mount the RS-232 card onto the
FX Supervisory Controllers:

1. If a station is running, stop it using the
platform Application Director view.

2. Remove power from FX Supervisory
Controller.

3. Remove the FX Supervisory Controller

cover. To do this, press in the four tabs on
both ends of the FX Supervisory Controller
and lift off the cover.

Note: If accessory modules are plugged
into the FX Supervisory Controllers, you
may need to slide them away from the unit
to access the cover tabs.

4. If the battery and bracket is installed,

remove it by taking out the four screws
holding the bracket in place. Set the
screws aside for later.

5. Unplug the battery from the connector on

the FX Supervisory Controllers (Figure 2).

AVERTISSEMENT: Risque de décharge
électrique. Débrancher l'alimentation avant

de réaliser tout branchement électrique.
Tout contact avec des composants
conducteurs de tensions dangereuses
risque d'entraîner une décharge électrique
et de provoquer des blessures graves, voire
mortelles.

IMPORTANT: Make sure to plug any option
card into its connector properly (pins
aligned).

IMPORTANT: Avoid hot plug-in or the
removal of any option card from the FX
Supervisory Controllers (or other accessory
module). This means you must first remove
power from the unit.

6. Remove the blanking end plate for the slot

you are installing the option card into.
Retain the blanking end plate in case you
want to remove the option card at a later
date.

7. Carefully insert the pins of the RS-232

card into the socket of the appropriate
option card slot. The mounting holes on
the RS-232 card should line up with the
standoffs on the FX Supervisory

Controllers. If they do not line up, the
connector is not properly aligned.

8. Press until the RS-232 card is completely
seated.

9. Place the custom end plate that came with
the RS-232 card over its connector
(Figure 3).

10. If you are installing or replacing the
battery or bracket, plug the battery cable
into the battery connector on the FX
Supervisory Controller. See Figure 2 for
the location.

11. Set the battery and bracket assembly back
over the option card slots, with the
mounting holes aligned with the standoffs.

12. Place the four screws through the battery
bracket, end plates, and into the standoffs
on the FX Supervisory Controller. Hand
tighten these screws with a screwdriver.

13. Replace the FX Supervisory Controller
cover. If accessory modules were
unplugged, plug them back into the FX
Supervisory Controller as before, and
secure.

14. Restore power to the controller and verify
normal operation.

Wiring

The RS-232 card uses standard DB-9M plug
and pinouts (it is identical to the RS-232 port
on the FX Supervisory Controller base). To
connect the FX Supervisory Controller RS-232
card with a Data Terminal Equipment (DTE)
device, use a null modem cable with DB9
connector.
