Britt,

How did you do this?

I have a 2100-I, too, and I'd like to install a GPS receiver in it to enable
the GPS sync/synt features.

(I could generate IRIG from a GPS receiver using a microcontroller and feed
that in, but that seems like too much of a hack.)

Anyone have a TS2100 with GPS?  The make/model of the GPS receiver used
would be a big help.    Ideally I'd love to see a few high-res pictures.

Christopher,

I called Symmetricom about this too, and got a little further- the tech
support guy told me he thought it was a Trimble ACE module.

I found an ACE-ii module in a surplus cellular survey receiver. When I
first put the module in and started up the 2100, I'd navigate down the
menu to GPS Health and it would always report 'GPS Engine Busy'. I knew
the module was fine, because the survey receiver worked; it had a serial
output that kicked NMEA strings out. I found a ACE-iii technical manual
on Trimble's website and it of course described the 3 different
protocol's that the ACE could be configured for (NMEA, TSIP and TAIP). I
figured it was a protocol issue and I chose TSIP to try because it had a
command to set the clock to over-determined mode(OD). This has been some
time ago (over a year I think), but I'm pretty sure that's the protocol
that worked for me. I simply built a 232 driver and used the Trimble
utility to change my module from NMEA to TSIP (or maybe HyperTerm, don't
quite recall, as I used all the utilities from Trimble and HyperTerm to
flip modes). Anyway, go find a ACE module and set it to TSIP and I bet
you'll be fine. My '2100-I' model has been up and working fine for the
last year.

Don't forget you need a pigtail for the antenna- The provided hole on
the back panel is for a SMA connector.

I have recently bought a 2100-GPS model that doesn't work, but it did in
fact have a ACE-ii in it. Also a StarTime display I bought had one in it
too. I can take pictures of both this weekend if you like. I'll be
dis-assembling the defective 2100-GPS unit to determine more about the
unit relative to adding the Rb oscillator.

Anyone like to host the images for me?

Regards,
Britt

they got bought by Symmetricom, the GPS were always Trimble, and used the
TSIP protocol. Never sold one with a Rb though, although we did get one
upgraded. I'm pretty that it was more than just adding the Rb and a PSU.
