Comparing the output to a gps 10Mhz, the original was jittering all over the place and not very nice on an sa either. Didn't have the exact fit, but did have a small ovenised vcxo which had the right vcc and control range. Epoxied that the the board, but had to add a squarer (a single transistor) as it had a sine wave op. So, it's been hacked around a bit already. One thing I did notice in the eeprom, 4th line down, first six bytes, is the ether mac address, but haven't edited any parameters as yet. Right now, it's running on a ups, along with a couple of other what I call, "essential loads" :-). As for user setups, from memory, there are two eeproms on the board, so may swap the other item to see if it fixes the fault...

[time-nuts] Symmetricom TS2100 Faults and Forgetfulness
Hi, Thanks for all the replies. Looked into the Heol replacement gps module, bit bullet and ordered one. Arrived today and on re power up, the system was tracking 8 satellites 3D in 3 or 4 minutes. Quite impressive really and a great improvement on the original module, even without the firmware issues. Still have the power down / losing setup fault. If it's powered down, the next power up shows cleared network info, ip, mask and route etc, together with rubbish on the display.May be other parameters as well, but my guess is that it's reverting to defaults, perhaps because of a checksum fault in the firmware or eeprom. Will try re installing the firmware, which I updated to the final version sometime ago, but apart from that, no idea what the fault might be. Eeprom dump included. If another member has one of these, do these values look sane ?. No idea of function though...

Chris - Did you update this TS-2100 with HEOL Design’s replacement GPS receiver? Several time-nuts participants (and some scientific organizations) performed this update/upgrade (including me), replacing the obsolete TrimbleACE III GPS receiver. http://www.heoldesign.com/N024-GPS-receiver-board-for-Tymserve-2100 — On January 2015, TymServe 2100 servers started failing in the time displayed, and there was 1 second offset. On May 3, 2015, the TS2100 showed another bug, by displaying an incorrect date : September 17, 1995 (1024 weeks earlier, GPS Week Number Roll-over). Symmetricom (Microsemi) published a note about this WNRO bug, explaining that no fix was available (from Microsemi). HEOL Design (France) developed a solution for these TS2100 issues. http://www.heoldesign.com/IMG/pdf/heol-tech_note_119_en_r02.pdf HEOL DESIGN Pôle Phoenix Route du radome 22560 PLEUMEUR BODOU France T: (+33)296 48 46 05 M:(+33)603 55 19 45 E: cont...@heoldesign.com — greg, w9gb Subject: Symmetricom TS2100 Faults and Forgetfulness Date: Mon, 26 Nov 2018 18:31:30 + From: Chris Quayle To: time-nuts-requ...@lists.febo.com Hi, Question for the group. I have a Symmetricon TS2100 which has faults. It's been some time since it was last used, but powered it up recently to find that it had lost it's setup data, display showed rubbish and the year is stuck at 1997, though the time of day is accurate once it has achieved 1pps lock. Apart from that, everything else looks ok. The display can be reset with the "root util display 0x97900" command and the firmware was upgraded about a year ago to the latest revision from the symmetricom site. Just wondering if it could be a faulty eeprom, but not managed to find a schematic or service data for it, so difficult to debug at a hardware level. Any suggestions would be welcome...
