Info in FAA FA-10046 Time Code Display and IRIG....

[Nick]

Just found one of these in my store, NIB...

Two things... it's 110V only and needs 60Hz for its fallback mode (when the IRIG feed is not available)..

I'm in the UK where we have a more sensible 230VAC @ 50Hz (joking). So, I can power this lovely (small) beast with a standard step-down xfrmr but I'm going to need to get an IRIG feed.

I'm starting on an NMEA->IRIG converter, but due to the timing sensitivity of IRIG, it may have to be on an FPGA. Not sure yet.

Has anyone done this (or attempted it) already? I don't want to re-invent the wheel, so if anyone has sensible code to generate IRIG-x that they're willing to share, I can do the rest...

I'm also after TECHNICAL information on the FA-10046, specifically signal levels and pin-outs for the IRIG feed and a service manual or schematics would be just fab! Not found a user manual yet either, even though this seems to have been designed and built on an FAA contract (DTFA01-84-C-00036).

Thanks

Nick (the real one!)
