BIT cable configuration - disconnect not active slice

After radio repair, I am still trying to find a solution to disconnect other slice when TX on the active one. Basically protect 2nd slice from overload and paying another huge bill. One avenue I am exploring is a BIT cable. I purchased one and trying to figure out if it possible.

Problem statement - Flex tell me that I should see and overload message and protection system should be preventing the damage. On my 2 events, my 2nd slice dying, I never see that messages and there is no any explanation why it is happening. I tried to have conversation with Flex, but seem like no one had a good model.

Task - Need 2 active outputs - One output 0V while another 3.3V and opposite, the idea to install 2 rellay's and disconnect slice that not in TX state.

This is for 2 antenna usage on different bands and disconnect antenna that no in TX. I cannot find a working solution in BIT cable yet. I was hoping to do it with One bit set for TX Antenna/ANT1 and set another bit for TX Antenna/ANT2, but any time I switch to Slice 2 activate TX and ANT2 with below settings , nothing changes.

Also tried to see if i can make it configured by TX slice, but switching between slices i do not see a voltage change.

I am plying with it over few hours, thought it should be simple, but cannot yet figure it out.

Would appreciate some assistance.

Thanks,

Sergey
