8 Digital Inputs
8.1 S.BUS Input
The S.BUS input port can be used. It is a standard used for Futaba RC controllers. Only the rst version of S.BUS
is supported.
Mechanically, a common servo‐wire like 3 pin jumper cable connector is used for S.BUS.

Pin Descripon
1 GND
2 VCC 5V out
3 S.BUS in
Warning: The +5V wire on the S.BUS input is intended for powering otherwise unpowered transceivers
and converters from WIRIS Pro. If your transceiver or convertor is powered otherwise, do NOT connect
the +5V wires and leave them unconnected instead, only connecng the GND and S.BUS pins. If the +5V
wires are connected, damage of either device might occur.
S.BUS allows transmission of many servo‐like channel PWM signals through a simple three pin connecon. The
device is compable with S.BUS enabled receivers and converters such as the Futaba SBE‐1 PWM‐S.BUS con‐
verter.
