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: [email protected] — greg, w9gb ==== Subject: Symmetricom TS2100 Faults and Forgetfulness Date: Mon, 26 Nov 2018 18:31:30 +0000 From: Chris Quayle To: [email protected] 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...
