Larry - Interface Boards for Motorola (and Garmin) receivers have been discussed (and sold) by TAPR since late 1990s. TAPR archives all of this documentation, for discontinued GPS kits, can be seen on the left margin. https://www.tapr.org/gps_exp-kit.html Tom Clark, W3IWI Total Accurate Clock (TAC) project (1996) covers the entire topic. https://www.tapr.org/kits_tac2.html Simple interface board schematics (Serial Level converters, and voltage adjustments for external antennas/ 3.3 or 5 V) can be found throughout the Internet since mid-1990s. Numerous radio amateurs DIY their own (breadboard) or sold small interfaces at hamfests (1996-2006), until newer GPS solutions became surplus (and smartphones with built-in GPS appeared after 2007). Doug McKinney, KC3RL (SK, December 2006) offered interface boards for the Garmin (GPS-25) and Motorola receivers until about 2005. I have one of Doug's boards in my GPS parts box.

I would like to add mention of the M12+ interface board that Tom Wimmenhove offered on this list. I am using them to lock PRS10s. Very happy with it.

Hi At least from a quick read of the TAPR page it’s not real clear if the GPS modules are M12+T or just M12+ boards. I believe that if they don’t have the T on the end, they don’t have sawtooth / PPS (?).

Bob, Couldn't find a part number on the .jpg of the gps rx to to cross reference. Have a few +T's. Don't need another timing rx. Would take a few positioning rx's as the M12+ units are good for balloon launches. Reads out >65535ft. See top comment.

Norm and Bob, The M12+ GPS receivers mounted on the motherboard are indeed the timing units. Chapter 5 of the Motorola M12+ User's Guide is here: http://www.synergy-gps.com/images/stories/guides/m12+userguide.pdf The binary commands and output messages, including timing related commands, are in Chapter 5 starting on page 59. The M12+ timing receiver can also be used for navigation applications - simply don't use the Position Hold mode. The main difference between the M12+ navigation receivers and the M12+ timing versions is that the navigation boards have a faster TTFF. Motorola didn't refer to the M12+ timing version as "M12+T" That designation was used by Synergy, and others, to clearly differentiate the timing version from its navigation counterpart. We recently forwarded information to TAPR on where to purchase front and rear end plates for the housing and also dimensional information on the hole sizes and locations. Until that info is available from the TAPR.ORG web site, we'll be happy to forward that information to anyone interested off list.

Worth looking closely at these if you've bought one. On mine, apart from the connector to the DB9 being pulled off and some pins bent, which I could fix, there are two tiny SM ceramic caps that have been knocked off the M12 GPS board, both hanging by one of the detached PC traces. This I may be able to fix, but I'm not certain obviously :^) Dan - ac6ao

hi after carefully crafting the suggested db9mf cable (with 16vdc on 7 & 8+) i powered up, but no green led... the db9 to chassis seems ok. but am still engaged. there is no voltage across the backup battery (the holder seems slightly bent). the lack of a schematic for the mobo is a big problem. any documentation on the 10-pin interconnect to the m12 would be nice. i guess this is what you call a slow start... 73 dave - k5en On Thu, Apr 6, 2017 at 11:49 AM, Dan Rae <danrae@verizon.net> wrote: > Worth looking closely at these if you've bought one.

Folks, The TAPR GPS Kit documentation has been updated and revised for clarity (I hope). it includes details for purchasing end plates and also dimensions required to fabricate end plates. The TAPR GPS Kit document, and a motherboard schematic for reference, is now available on Synergy's "GPS for Scholars" page: http://www.synergy-gps.com/index.php?option=com_content&task=view&id=54&Itemid=73 Art -----Original Message----- From: time-nuts [mailto:time-nuts-bounces@febo.com] On Behalf Of Gregory Beat Sent: Tuesday, March 28, 2017 11:48 AM To: Larry McDavid <lmcdavid@lmceng.com>; time-nuts@febo.com Subject: Re: [time-nuts] TAPR Oncore M12+ kit Larry - Interface Boards for Motorola (and Garmin) receivers have been discussed (and sold) by TAPR since late 1990s.
