WinOncore12 was Motorola's first Windows application coded for the original M12 and, in 2001, the new M12+ timing receiver. WinOncore12, and the later SiRF Oncore application, only recognize 6 and 8 channel VP Oncore commands to the extent that they are common with the M12x receivers (not that many).
Motorola only offered the DOS based "GPS Controller" software back in 1997 so Synergy commissioned Rick Hambly at CNS Systems to produce a sub-set of his TAC/32 Windows controller application for us - it's named SynTAC. SynTAC (like TAC/32 and TAC32Plus) automatically recognizes and initializes every 6, 8 and 12 channel receiver produced by Motorola from 1992 to 2005 and ilotus M12M receivers from 2006 to present. This includes the original 6 channel PVT-6, 6&8 channel Basic Oncore, 6&8 channel VP Oncore, etc., etc. Since 1997 Hundreds of Hams, experimenters and educational institutions have downloaded the fully functioning 30 day evaluation version of the SynTAC application (without purchasing the product) to automatically setup and test Oncore receivers that didn't seem to work properly or were behaving oddly due to conflicting setup commands.

This can be done with a MAX232 chip (or equivalent). Then the pinout (refer to the engineering notes previously mentioned, page 9): pin 2 and pin 3 are the main power supply (2: +5B and 3 GND) and the serial port pins are pin 8 TX and pin 9 RX. The TX pin must be routed to the TTL to RS232 translator and then to the RX of the PC (pin 2 if a DB9 is used or pin 3 if a DB25 is used). Pin 9 comes from the translator and from the PC TX pin (pin 3 DB9 or pin 2 DB25). The WinOncore software can be used to test the receiver. Don't forget to connect an external (that is on the roof) GPS antenna and prepare your 'scope for the PPS on pin 6. The PPS should be pretty visible as it is 200mS long (see page 7).
