VTX is not there to select for serial config to update TRAMP HV with channels

[BoLtWD]

I don't know if this is the correct place to post this sorry if not,
Using KISS FC firmware v1.3RC30 & GUIs v1.16.15,

I have set up Lua Script and the Kiss FC is talking to the radio displaying pids and channels on two of my kiss Quads but if I change the VTX channel the KISS FC Changes but not the TRAMP HV.

From the TRAMP HV I have the T output to the Kiss TX pin.

The main reason I am posting in the GUI section is in the GUI I have the VTX Type as TRAMP HV but I only have in serial config OSD not VTX setting. Due to this I don't know if this is why the TRAMP HV is not being updated by the kiss as VTX is not there to select.

Have you any advise to help me and where to post if I need to take it to others to help?

Thank you for any help you can provide.

Just put a scope on the TX pad of the kiss FC, All I am getting is a constant voltage no signal or wave of any kind when I update the Kiss with the radio to change the channel. The channel is changing in the Kiss FC just that the Kiss is not sending anything out of the board TX to the TAMP. Like above I only have OSD for the drop down serial config NO VTX as tutorials say. This is the same problem on my other Quad with a Kiss FC so so this must be related to a setting as far as I can see.

Can you advise?

Thank you,

This was confusing as I could not see anything regarding connecting the TRUMP to the Kiss FC except for TX2 to T on TAMP.

I have connected the TRUMP T to port 1 pin 5 (TLM) TX3 and have a digital signal cumming out shown on my scope that seams to drop out possibly updating when I press save on my radio LUA script. Unfortunately the trump is still not changing channels yet all connections checked out ok. The Kiss FC is changing channels just the TRAMP HV dose nothing.
I disconnected the wand RACE PROGRAMMER in case this was interfering but this did not help.

Connection the TRAMP HV to TX2 would not have damaged anything (I cant see how)?
I will have to try this on my second Quad and get back to you.

Just a thought could this be something to do with the vision of TRAMP HV I have?

If the VTX information is not appearing in "advanced" page then it might be the wrong pin is connected to VTX. In some documentation it says use RX3 but thats not correct for my "KISS FC V2" it should be a TX port in my case it's TX5. The FC can't read (RX) changes to the VTX it needs to write them (TX)

There are multiple versions of the LUA scripts, the newer ones are separated into modules and require both the LUA file and the "KISS" directory to be copied into the "SCRIPTS/TELEMETRY" directory in Taranis SD card. Check the release page for your FW version, this is the one for mine. https://github.com/fedorcomander/kissfc-tx-lua-scripts/releases/tag/0.9

From my experience in short:

No VTX info in "Advanced" page of KISS GUI = FC to VTX connection is not working (TX pin not RX)
VTX info is showing in KISS GUI = LUA script issue, match script with your FC version and make sure the telemetry is working correctly..

u need to use. gui 2.0.0, lua 0.9... vtx connection is no more attached to serial, thats why there is no vtx in serial config. T/SA must be on RX3 on v1 and TX5 on v2. Its be-directional - so dont mind RX3 on V1. Port is configured to be as "2" ports anyways ;) Latest GUI will show VTX config no matter what you choose in serial.
