Remote Data Link
A remote data link using data modems will be required
if the GTI database must be configured from a location over
50 feet from the GTI units. The amount of additional
equipment required will depend upon which one of the
following two methods is used:
1. Internal GTI Modem - Use the internal 1200-baud
modem built into each GTI unit and the telephone line
connected to a GTI unit. This method requires the
following additional equipment:
•
1200-baud modem at GTI Configurator location
(internal or external - cable required if external)
•
Available telephone line at GTI Configurator
location and a cable to connect from the telephone
line to the modem
2. External Modem - Use an external modem at the GTI
unit location connected to the RS-232 port on the back
of a GTI unit. This method requires the following
additional equipment:
•
External modem at the GTI unit location and a
cable to connect it to the RS-232 port on the back
of a GTI unit
•
Matching modem at the GTI Configurator location
(internal or external - cable required if external)
•
Available telephone line or other communication
circuit and a cable to connect from it to the modem
(at both locations)
For additional information about using a remote data
link, see the Data Link To GTI Units section in the GTI
Configurator software user’s guide.
