[time-nuts] Looking For Info On A Kode/Odetics 375-642 TimeDisplayUnit

Most of these type of display rely on an input code, as they don't have an
internal oscillator. As I mentioned in my previous post to Jason, they are
probably code selection switches for IRIG A, B, NASA (36?). Alternatively
they may give the unit the ability to read modulated or un-modulated Time
Code inputs. I worked for Odetics/Zyfer, but the display products were being
obsoleted at about the time I joined. I may have an Odetics catalogue
lurking around in a box somewhere which may shed some light, but I don't
have any manuals for this product line.

Now you know why I was wanting a poor man's IRIG-B generator, which I'm
having issues getting the audio drivers to compile on my Geode box, so until
I fix that I can't use the other file from the NTP distro.

Anyhow, I got a Kode/Odetics 375-642 Time Display Unit. Basically it just
displays the time via an IRIG-B input on a nice bright LED display. It works
great, I have no complaints, but I'm just curious about 3 little dip
switches on the board (4th picture in URL below).

Does anyone have one of these or have a manual? I'm curious what those
switches do. I'm hoping maybe one will allow the clock to free-run when the
IRIG input is disconnected, right now it freezes if you unplug it. Also
maybe a 12/24hr conversion? I dunno...
