VCU to CAN switchboard output

I have a CAN switch board V3 connected to a VCU 7 via CAN 2. Everything is working great, switches, analogue inputs, everything is good.

What I am trying to configure in the ADU software is to activate the output channels on the CAN SB.

What I am trying to do is create a custom function to use CAN channel c_csb_switch3 to activate a LED light on c_csb_output2, using a flashing function.
I’m not sure if there is another additional step required to output the correct CAN signal to the switchboard (state 0 to 1)? So far I haven’t been able to find a help file that explains how this might work.

Import canx for csb all statuses are there

I have imported the CAN dbc file, there is no communication issues.
I’m just trying to work out how to get the ADU to switch output c_csb_output2 on the switchboard using the function feature.

here you have (in manual you can fid it also)
you need to send frame like below
