I have attached a couple of docs I wrote some time ago concerning the differences. This should be helpful. There were no production releases between 2.2 and 3.0. 3.0 was so different from 2.2 that Motorola decided to indicate a major rev. by going to v3.x. Hardware did not change at all. It's easy to reflash these units, but it can only be done here at Synergy. The code is encrypted and needs a hardware dongle and a custom program to do the reflash. This is a $25 process. If anyone wants to discuss re-flashing please contact me offline so we don't start taking too much bandwidth from the list. The 100PPS works fine in both 2.2 and 3.2. It actually worked well in v3.0 but 3.0 had other problems. When Motorola recompiled for 3.1 to fix the problems in 3.0 the 100PPS bug snuck in. v3.2 fixed that and was the production firmware until the UT+ was discontinued.

F.O.Q. (Full of questions!!!) First, is the Oncore UT+ the same unit as the M12+? And if not, are there significant differences between both units? Briefly, would you suggest me to spend more on a M12+ than a UT+ ?? (or let me wait until july for the allnew M12M...) Also, Randy Warner suggests only versions 2.2 or 3.2. What happened between versions 2.2 and 3.0 ? (it looks like that there have been major hardware changes...) And... Is it easy to reflash one of those units? (do we need special hardware, and are reflashing software / firmware easily available on the Net?) Finally....On R5122U1112 (version 2.2), how is the 100 PPS behavior? (if i refer to the PDF file uploaded by Randy, a significant correction has been brought to the 100 PPS only on the version 3.2 firmware...) Thanks and 73 de Normand VE2UM. P.S.: Are transactions accepted on this forum? (for example, asking anyone if they have GPS boards for sale..) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
