GCU Wiring

For WKM, connect to any spare CAN-Bus port of the flight control system via a CAN-Bus cable.
For A2, connect to the port labeled CAN1, located on the A2 Controller unit or the CAN port located
on any modules which are already connected to the CAN1 port via a CAN-Bus cable.

Turn to next page to obtain the
correspondence between the GCU
channels and S-Bus/PPM channels.

Battery

Connect the XT60 to the GIMBAL on center frame if S800 EVO used.
Attention that S800 EVO power supply voltage should be within the defined limits (6S), when
using one battery for both S800 EVO and Gimbal power supply.
Refer to S800 EVO User Manual for details.

Gimbal Control Unit (GCU)

Make sure the ports are accessible when installing the GCU so as to facilitate wiring and software configuration.

In 3-pin ports, pins near the nicks are signal pins.

6-pin cable for G6, 9-pin cable for G9.

DO NOT cover the heat sinks, keep them unobstructed.

The GCU module is NOT water-proof or oil-proof.

RC Receiver

These are example connections. The signal of The aircraft will transmit through the DJI Lightbridge ground system. After

connecting to the DJI Lightbridge, then it is not necessary to connect with the RC receiver.

Prepare 2 TXs, one for gimbal control, the other for aircraft control, refer to the 2-Pilots Solution in the Appendix .

If one receiver is used for aircraft and gimbal control at the same time, please refer to the 1-Pilot Solution section of the

Appendix for more details.

Set Aileron, Elevator, Rudder channels on gimbal control TX. Command stick stands for gimbal rotation velocity, center

position is 0, endpoint for maximum velocity (both clockwise and counter clockwise ) is 100%.

Choose one 3-position switch/channel as Z15-BMPCC working modes switch (MODE).

Choose one 2-position switch/channel as the camera record control switch (AUX3) as a camera lens orientation switch in

Reset Mode (AUX2), and one 3-position switch/channel as a camera aperture switch (AUX1).

Please refer to A2/WKM User Manual for aircraft settings. Connect the receiver to GCU correctly.
