(7) Point-to- MultiPoint Repeater
Sets the radio as a Repeater in MultiPoint mode. The unit will receive and re-transmit packets to signicantly extend the
operating range and network reliability where needed.
The unit can be used as a remote and a repeater if the Slave/Repeater mode is set. When Slave/Repeater is set, packets
are sent across the network as well as the local RS232 port. Reducing the need for a separate repeater and a remote.
Note: To operate a radio as a MultiPoint Repeater and remote, Slave/Repeater must be set to 1 in the MultiPoint
Parameters menu.
Note: Options in Blue are SRM models only
