Satellite receiver connection

A satellite receiver (such as RSAT2 or REX3) can be connected to the E1 or E2 port on the REX A receiver. In this case, REX A acts as the main receiver with activated flight stabilization and RSAT2 is used as a backup in case signal loss occurs. You can additionally use the Double Path mode in your transmitter.

Central Box connection

The REX A receivers are able to generate the EX Bus serial output with up to 16 stabilized servo channels. This stabilized output can be used for airplane models equipped with a Central Box.

*) The RSat 900 (or anything connected to the Rx2 port of Central Box) is only a supplementary device. The Central Box should never switch to this backup receiver while the REX A is functioning correctly. REX A stabilizes the EX Bus output always, even if it does not have signal from the transmitter.
