Note that on GLM Opto boards the opto transmitter and receiver pair need to be correctly matched. In a normal Williams opto board the transmitters are all just 12V and ground and it doesn't matter which receiver each one is paired with. On the GLM boards in order for the diagnostics to work right (and the board itself to work right) each pair needs to be mated with the correct one. I don't know if this applies to the TZ board but I do know for certain that some (all?) BSD castle optos don't have the transmitter and receivers correctly paired with from the factory.
