This section demonstrates the programming of a GINA connected to a Model 170 controller
operating at 1200 Kbps. This depicts a Host/Master to Remote operation utilizing the use of a
repeater.
4.
The following section deals with software settings.
a.
If “Traffic View” from Wapiti Micro Systems Corp. is utilized, set “Delay Factor” under
TV Configuration menu to at least 5. Any setting below 5 will result in communication
failures.
b.
If “TransLink” from Integrated Software Solutions, Inc. is utilized set, “Message Delay in
Milliseconds” under System Timings of the Communications Setup screen to 200. This
setting has been tested with up to three repeaters in the path.

NOTE:
TRANSMITTER ID AND TRANSMITTER PATH ID numbers are user selectable
however Host/Master should be different than the Remotes.
Above example is for a one repeater system. If more repeaters are required in the system,
add repeater numbers to the Transmit Path (TXP) statement in the order they will be
accessed.
Example:
Host has to contact Remote via three repeaters numbered 10 (closest to host), 20
(midway between units), 30 (closest to Remote); the Host TXP statement would appear as
TXP=10,20,30. The Remote TXP would appear as TXP=30,20,10.
