COR Polarity:
This sets the polarity the BTD-2 looks for to see COR as active, GND (Ground) or V+ (+5 V). The
BTD-2 looks for an active COR to validate a tone, so as not to false. The unit also resets the latched outputs by
seeing COR go inactive.
Squelch Polarity:
This sets the polarity of the output of the Monitor/Squelch Output, GND (Ground) or V+ (+5 V).
Monitor Input Polarity:
This sets the polarity the BTD-2 looks for to open the squelch of the radio to look for
activity, GND (Ground) or V+ (+5 V). When this input goes active the BTD-2 activates the Monitor/Squelch
Output.
