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 ports receive audio out the ports 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 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 064 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 ports receiver without keying the ports transmitter. Because the

controllers full duplex ports, the controller can be monitoring another ports 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
