Dear sir 
we don’t have a data bus reader but I saw in your video that you taking ARINC live data 
Using  RTX Software can you tell me how to connect laptop to LRU Rack if I got RTX software 

I have checked the wiring everything is ok and voltage is also coming on the antenna connector
there is nothing in the display Which tells us that data is coming we are not able to select stormscope on display 

PN342 is IAPS( integrated avionics processing system) I think it’s taking some data from there ( heading ) 

We also checked for bad receivers. Like disconnect two and connect only one displays at a time and check for all one by one
Now we have doubt on antenna

During troubleshooting I check wire for 5 parameters

1. E- End to End
2. G- Ground
3. O - other ( connect for nearby wire )
4. S- shielding 
5. I - Insulation
if anything other Then this pleases add
