Team Black Sheep Crossfire RC System - Manual

N.i. SBUS
Not inverted SBUS is the same as SBUS except that the signal is not inverted. This can be used for FCs that
have no signal inverter built-in and require SBus as input signal.
MAVLink
MAVLink is a very lightweight, header-only message marshaling library for air vehicles. Most of the
common flight controllers support the MAVLink message format. For specific message documentation
please refer here: MAVLink Messages
If you select “MAVLink TX” on one of the available outputs the corresponding output will be set to “MAVLink
RX”. There is no hardware flow control required as we support software flow control (RADIO_STATUS
message) on both ends. You can connect it to any telemetry port of a MAVLink compatible FC. The MAVLink
baud rate is set to 115200 baud (since FW 6.xx, 57600 baud before 6.xx). The MAVLink TX pin needs to be
connected to the FC telemetry RX pin and the MAVLink RX pin needs to be connected to the FC telemetry
TX pin. The CROSSFIRE supports MAVLink V1 and V2, which will be selected automatically by the incoming
messages.
You use the MAVLink connection to send your RC data as well. If your FC supports MAVLink V2, this
includes up to 12 channels, with V1 up to 8 channels.
PWM (Ch X)
If you select CH X, the CROSSFIRE will output a standard 50Hz PWM signal, that can be used for all servos
and FC’s without digital RC input.
PPM
Sends up to 12 channels by PPM. Only use it on old-style flight controllers with no serial RC input.
DSMX
DSMX is designed to use the CROSSFIRE as a backup system for Spektrum receivers.
RSSI
Translates the RSSI from 0 - -130dBm to PWM signal from 2000µs to 1000µs. This can be used for old-style
OSD’s with only analog RSSI input
