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.

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.
