Since the TADD enclosure has two DB-9 cutouts, one nice option (which
I haven't tried yet) would be to wire the LED, the 5/10 MHz jumper,
and the ARM switch connections to a DB-9 and mount that in the
enclosure, then mount the LEDs and jumpers to a mating connector.
I was actually contemplating the same. I think that would be a good
solution. It would also allow for remote control and monitoring. Tossing
in a PPS in there should not be hard and would make sense.
There's a "secret" extra PPS output available that could be used on the
DB-9. Look behind the ARM connector and you'll see a pair of pads
labeled "AUX PPS". Those are a simple PPS signal buffered by a leftover
gate on the 74AC14. Not a nice low Z output like the primary ones, but
potentially useful...
