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.

REX A settings:

Fail-Safe Fail-Safe type Output period E1 E2 Stabilize EX Bus
Enabled Intelligent 7-20ms PPM Input E.g.  Sensor NO

 

RSat2 settings:

Fail-Safe Output period Output type Receiver mode PPM mode
Disabled Auto PPM positive Normal Direct

 

 

 

 

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.

REX A settings:

Fail-Safe Fail-Safe type Output period E1 E2 Stabilize EX Bus
Enabled Intelligent or Off *) Auto or 7-20ms PPM Input EX Bus YES

 


  

RSat2 or RSat 900 settings:

Fail-Safe Output period Output type Receiver mode PPM mode
Disabled Auto See the picture Normal Direct

 

 

*) In the Intelligent mode, the REX A stabilizes always the EX Bus output and the Central Box should never switch to the 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.

On the other hand, if the Fail-Safe type is set to Off - Assist disabled (min. REX A version must be 1.10), the receiver will disable its EX Bus output when it loses signal from both wireless and PPM links. This will allow Central Box to switch over to the secondary (backup) serial input.
