Serial Port Programming
Wire Line
This mode is not supported in the Model 6203 for IP FSA systems.
VOX
This communications mode is designed for use with a conventional radio interface where
the Model 6203 uses its own internal circuitry to detect channel availability. If the Model
6203 detects noise above a threshold set by the VOX potentiometer, it thinks the channel
is busy and does not transmit. When this mode is selected the COR input is ignored by the
Model 6203. The Model 6203 attempts to transmit status changes as soon as they happen.
It does not need to receive a poll from the Model 26 in order to transmit (exception
reporting).
COR Communications Modes
There are two different COR (Carrier Operated Relay) communication modes: TX on
COR High and TX on COR Low. For the purposes of IP alerting, the COR TX on COR
Low mode is used and the COR input is always grounded.
Trunking Communications modes
This mode of operation is no longer supported in IP network-based systems.
“Alerts” Menu
This menu selection is accessed from the Main menu. It is used in the configuration of
alert commands and appears as shown in Figure 15 when selected.
