Repeater
Setting the Radio Operation Mode to Repeater allows the transceiver to operate as a repeater. The Repeaters Used checkbox should be selected if there are any repeaters in the network; it should be set the same for all transceivers (see Device Configuration Utility screen showing settings for repeater).
NOTE:
A maximum of four repeaters are allowed in a network. When a repeater is used, the RF throughput is cut in half. Throughput is the rate at which data is sent or received. Reducing throughput means less data can be transmitted in a specified amount of time.
