4 .2 .4 Connection of single line receiver with additinal servos connectors (e .g . S-bus, SRXL)

Connect the receiver to the MICROBEAST with one of the supplied regular 3-wire cables. Plug the cable into 

the MICROBEAST input [DI1] and the other to the receiver to the output [S. BUS] or [B | D] ® for Multiplex.

Please make sure that the connectors are plugged in with the correct polarity. Be careful, since the supplied 

cable is designed to be used universally, and the Futaba® polarity protection tab missing. On the MICROBEAST, 

the orange signal wire must be close to the top cover. 

This description also applies to other single line receiver with additinal servos connectors (e .g . SRXL 

receivers (Multiplex or beASTRX)):

We recommend to directly connect speed controller and additional functions to the receiver to use the Failsafe / 

Hold functions of the remote control system (see 4.2.1). But you can also CH5 and CH6 on the MICROBEAST for 

these functions!
