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.
