 2350A Modem Installation
2.15.2 2350A Modem Installation
To install the Internal Modem for the 2350A 
GC Controller, follow these steps:
1. To add a modem, at the GC Controller site, 
remove the Controller enclosure's front 
panel. 
(a) For the explosion-proof Controller, the 
front panel is secured by 16 screws. 
Remove those screws first. 
(b) Then carefully lower the front panel on 
its bottom hinges. The front panel is 
heavy, so make sure it does not drop and 
cause damage. 
(c) For the rack mount Controller, the rear 
of the enclosure is open; it allows access 
for most field wiring procedures without 
removing the enclosure. 
2. Locate the GC Controller's Terminal Board 
for Field Wiring (TB). The TB is attached to 
the GC Controller's Card Cage Assembly, 
facing the enclosure's front panel. (In the 
rack mount Controller, the TB faces 
outward toward the rear of the enclosure.)
3. Loosen the six screws that secure the TB. 
Then unplug the TB from its connections at 
the back, top of the board.
4. Lower the TB down and out of the way, held 
in place by its ground straps at the bottom 
of the board. This exposes the Card Cage 
Assembly.
Refer to P/N 3-9000-537  2350A GC Hardware manual 
for COM settings and pinouts.
