Problem on connecting gimbal to the pixhawk by serial/telemetry interface

Hi Everyone…,

I want to update this issue. I’m trying to get the serial interface of 3 axis gimbal controls to pixhawk through the telem2 port.

Connecting the gimbal controller serial pins (tx, rx & gnd) to the pixhawk telem2 pins as a below order. Rx to Rx Tx to Tx & Gnd wire connected to the any one of the ground pin.

The following setup has been carried out through the GCS

MNT_TYPE to 3

MNT_ANGMIN_ROLL to -3000

MNT_ANGMAX_ROLL to 3000

MNT_ANGMIN_TILT to 0

MNT_ANGMAX_TILT to -9000

MNT_ANGMIN_PAN to -18000

MNT_ANGMAX_PAN to 18000

MNT_RC_IN_PAN to RC6

MNT_RC_IN_TILT to RC7

BRD_SER2_RTSCTS to 0

SERIAL_BAUD to 115

SERIAL_PROTOCOL to 7

The following configuration has been done at SimpleBGC GUI

RC_ROLL pin mode – Serial API

MAV connection – RC Serial_115200_none parity

After all these setup I can’t get the controllers talking to each other. What are the things I have to do for get the connection? Is there any other way to connect to each other through serial?
