2.16 CONNECT VIA GC EXTERNAL MODEM
2.16.1 HARDWARE SETUP
1. Halt any ongoing analysis runs.
Use the Control > Halt menu to access this
function.
2. Disconnect AC power from the GC
Controller.
3. For the explosion-proof Controller, remove
the cover from the GC Controller housing to
expose the GC Controller Terminal Board
for field wiring.
For the rack mount Controller, the rear of
the enclosure is open; it allows access for
most field wiring procedures without
removing the enclosure.
Ensure you have a pre-existing PC connection to the GC
unit before installing the external modem. If the GC unit is
already on location, do this via another remote operator
connection, or, onsite, via use of a portable PC and serial
cable. Ideally, configure the GC unit and install the
external modem prior to placement at the remote location.
Note: You cannot set the Serial Ports parameters from the
GC unit front panel.)
SERIOUS PERSONAL INJURY OR DEATH POSSIBLE
Before removing the unit cover from the GC Controller, make certain the
power supply switch is OFF and the AC power cord is disconnected. Observe
all safety precautions when you are working in a hazardous environment.
Failure to observe all safety precautions could result in serious injury or death.
