What does these series diodes do to protect the patch bay on the test fixture?
Each jack has a series diode to protect the test fixture, but how does it work

What is the jack size and plug size for these patch bays?

The Test Fixture has different outputs signals and waveforms or voltage of either AC or DC voltages. If a Tech connects the wrong jacks together the series diode protect the test fixture how so?

 

patch diodes or cables are used to switch inputs and outputs internally. they dont have signal going through them, but energize relays to switch the inputs.

The Diodes energize the relays how so? the diodes are in series or in parallel with the relay to energize it?
