Thanks to research made by Haven Cousins now we have pinout chart for CGPro Remote Controller TRRS jack to Expansion Box TRS jack. So you can create DIY cable and use CGPro Remote Controller with this Expansion Box.
UPDATE: It appears that CGPro Remote Controller use LANC interface for Start/Stop, Iris, Focus and Zoom. So some functions will not work without LANC connection. Or as an option you may may build more complex cable - TRRS 3.5mm jack to TRS 3.5mm jack S.Bus and TRS 2.5mm jack LANC.
Also here is another pinout chart made for One Little Remote Lite. It is based on research made earlier by Denny Smith.
I also want to add some notes here again:
- This Expansion designed to fit to SmallRig BMMCC 1773 cage and to dimensions of my other accessories. It also fits to BMMCC WoodenCamera cage.
- This Expansion Box designed as flexible and free adjustable DIY device. It is not made for any specific single controller in mind. Everything is connected with tiny Dupont Jumpers, so you can open the box and easily change cables configuration.
- All pinout specs and connection charts information available in this thread and in item description in marketplace.
- This Expansion Box provides separate S.Bus (or PWM or Genlock or Analogue video out), LANC and DC power connection.
- This Expansion Box uses 3 pole TRS jack sockets.
- Note that CGpro Remote and One Little Remote Light Controllers use 4 pole 3.5mm TRRS jack connection that combines S.Bus and LANC interface in one cable. They will not work "as is" with this Expansion Box. However to use those controllers with this Expansion Box you may create custom made DIY cable (4 pole TRRS jack to 3 pole TRS jack)
- I don't have any planes to use 4 pole 3.5mm TRRS jack socket connection into my Expansion Box because i think that it is bad idea to mix two different interfaces (S.Bus and LANC) in one cable, because it is impossible preserve free adjustable concept if use 4 pole TRRS sockets, and because TRRS socket is too long and won't fit to internal dimensions of this Expansion Box.
