5.5.Behavior of Repeater Units

When configured as a repeater, the unit listens for packets that qualify for repeating in addition to its normal functions. A unit qualifies a packet for repeating based upon the TOID or MYID value associated with the packet. The trigger for repeating a packet from a base station to a remote is the value in the packets TOID field. The trigger for repeating a packet from a remote to a base station is the value in the packets MYID field. You can establish up to eight triggers for each repeater unit.
