Repeaters

To provide simple network functionality the RFI-9256 provides a several Repeater modes and uses a

number analysis system.

The Back-to-Back Repeater mode configures

the Main serial port and removes its control

from the Serial Configuration Menu. To

connect the modems for repeater operation the

Main ports of each modem must be fully

connected so that all the serial lines are

exchanged.

This mode also has the option of synchronising the Slave and Master for increased performance, to do

this pin 10 of each Radio can be linked to pin 10 of the opposite Radio Modem.

The numbering system requires the following rules:

All Repeater radios must only have a two digit Rx Address (unit id).

All “End Point” radios should use a full four-digit Rx address (unit id) and will require a

mandatory two-digit extension number.

For example a destination “End Point”

radio’s Rx address may be 4022 and required

port may be the MAIN port, which is extension

00, so the End Point number would be 402200

(6 digits in total).

To dial a connection to MAIN port (Ext 00) on radio

4022

would be:

ATDT

402200

To dial a remote menu (Ext 92) connection on radio

4022

would be:

ATDT

402292

To dial through a back-to-back repeater the repeater Rx address will be prefixed to the dial string. In the

example the user is dialing a menu extension (Ext 92) on the remote slave “End point” radio (radio 4022)

using repeater 50.
