Hi, Nigel
To select GPS as the default input port, it was required to tie PIN 39 (of
50-pin FPC connector) to GND.

Many thanks for the information, I was just coming to announce the same but you
beat me to it, sure makes quite a difference knowing that:-)
I don't

All the UCCM receivers have a EXT option... but most refer to it as LINK.
Heather sets it to GPS on startup. I believe LINK/EXT selects an external
PPS/PP2S provided by the base station. I think they normally operate it in
GPS mode and switch to EXT if the GPS goes down.
I had to make several changes to Lady Heather to work with these... you may
have an earlier version.
How are you connecting the serial port? In the photo, I did not see the row
of four holes that is on the Trimble / Symmetricom versions.

These are Samsung's version of the "UCCM" series of GPSDOs. Lady Heather now
works with them. I had to tweak the code to handle their funky/erratic
end-of-line sequences... various versions of CR/LF, LF, LF/CR. Their STATUS
screen and some message responses are also a bit different.
