JULY 2010 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.
