Part of the increasing issue in dealing with DJI is finding good information on what their produts include and how to implement them. The Shutter feature in the A3/N3 is a good example. I wanted to find some information on how and/or where I could connect a Sony A6500 to either of these controllers via Lightbridge 2. What is the mapping/channel that is applied to this feature. Compounded my issue here, doing a Google search on the internet directed me to a DJI Wiki site. Well that sight is no longer. Who knows what it was replaced with.

I asked support about this a few days ago. I wanted to trigger the shutter pwm input on the GCU but when its connected to a gimbal through a CAN Bus port it apparently disables all GCU PWN inputs which is a huge integration hassle.

Have you checked page 5 in the Lightbridge 2 manual on this: https://dl.djicdn.com/downloads/ ... _manual_En_v1.4.pdf

Did you ever resolve this issue? Is the firmware up to date?

Being asked if the firmware is up to date gets old fast

I was told my a DJI Tech support rep that the inputs to the Z-15 5D gimbal are disabled when connected to the a3 through the CAN bus, if you can confirm or deny that with a rep who speaks fluent English and knows what I'm specifically asking about that would help.

My goal was to trigger the shutter input with a PWM signal from another transmitter instead of the DJI transmitter through the CAN bus. I tried using the A3 PWM outputs with our transmitter expansion kit but there's no response from the GCU. I looked at the PWM output of the A3 on an oscope and it's working so I know the GCU is getting signal.
