Example 1-1: Configuring a Port as a Repeater or Link
Repeaters and links indicate how a port is configured.
Repeater
A repeater is defined as a port that loops the port’s receive audio out the port’s transmitter.
When the receiver becomes active, the transmitter of the same port should go active. When the
receiver goes from active to inactive, a courtesy beep and hang time will be generated. It is
required that the radios on a repeater port be only full duplex.
To convert a port into a repeater port the following command is used
000 X X
Where X and X are the same number indicating what port the repeater is on
When the port is looped back the courtesy beep is on port 'X', ID's are started and routed to port
'X'. Time-out timers, if enabled, are running when port 'X's receiver is active.
Link
A link is defined as a port that does not loop the ports receive audio out the ports
transmitter. When the receiver becomes active, the transmitters of all connected ports should go
active except its own port. A link can be either half or full duplex. Full duplex links allow the
ports transmitter to operate without effecting the receivers function. Half duplex links are similar
to full duplex with the exception that the transmitters operation causes the receiver to be shut-off.
To convert a port into a link port if it is already a repeater port the following command is used.
002 X X Where X and X are the same number indicating what port the link is on
When the port is a link the courtesy beep is on port 'X' is only routed to port 'X' if the audio routing
variable is not 00 (Refer to Command 037-039 for audio routing variables). ID's are enabled but
only controlled by the other connected ports. Time-out timers, if enabled, are running when port
'X's receiver is active.
Monitoring a port
It is handy to monitor a connected port’s receiver without keying the port’s transmitter. Because
the controller has full duplex ports, the controller can be monitoring another port’s receiver while
the monitoring port continues to have a conversation.
To monitor a port from another port the following command is used
001 X Y
Where X is the port doing the monitoring of port Y, Y is the port being monitored
