I have a BIG problem and little experience (not enought) with Pixhawk ports.
I need to install MiniOSD, 3DR clone telemetry and Mavlink Led Controller, but they need Telemetry ports, and i have only 2 ports.
I have read about split Y cables of one Telemetry ports, but i dont know settings into FC.
Can i use serial 4/5 for connect one of this instead telemetry?
@lawfx if you need the same telemetry protocol at the same rates then I would recommend to use single port and Y splitter.
It is really nothing to configure.
The splitter itself is nothing special at all. You just connect Rx wire of all your consumers to a single Pixhawk’s port Tx wire. And the same way you must connect ground wires as well.
i have to do some settings once pluged in Mavlink LED ito serial 4/5 port? or it
recognizes it automaticaly and only need to activate in hardware panel?
You have to configure the serial port protocol and baud (SERIAL4_BAUD/SERIAL4_PROTOCOL for example) . Configure these in Mission planner, it’s obvious what settings are required.
Put a Y splitter into either of the telemetry ports. Connect the air radio to one side, and the OSD to the other. The OSD is a “listen only” device, so all the OSD needs is ground, +5 volts, and TX from the port to RX on the OSD.
