Don, Not a problem.
8 channel VP's are capable of sending out 6 channel messages just fine. Go to Rick Hambly's site: http://www.cnssys.com/Tac32/ and download the eval copy of SynTaC. Actually, lots of the guys on this group probably have a copy already. Hook up your receiver and start TaC32. If the serial port is Com 1 the TaC32 program should start displaying data as soon as the eval splash screen is gone. If not, go into the <Edit> menu and set up the GPS interface for the right Com Port request the "Mot Bin" protocol, and then press <OK>. Tac32 should automatically poll the VP until it figures out what mode it is in (in your case NMEA) and then flip it to binary. If you have an antenna plugged in you should see satellite tracking, GPS fixes, etc. If you look in the lower right hand corner of the main window you should see something like: Motorola VP, 8 Ch, has DGPS..... I can't remember the actual wording. By default TaC32 enables the 8 channel @@Ea and @@En messages along with the @@Bb messages. To switch to 6 channel mode, click on <Data>, <Set Receiver Parameters>, and under "Special Purpose Modes" select "6-Channel Mode". When you click on <OK> Tac32 will turn off @@Ea and @@En and turn on @@Ba and @@Bn. @@Bb will stay the way it is. The lower right hand corner of the main window should now indicate that you are in 6 channel mode. The Z3801 should now work fine. About the battery: Just dragging down the battery will not clear the message formats on a VP. On the VP's all of the set-up info was stored in EEPROM. The only way to change things was to overwrite (as we just did here) or default the receiver with the @@Cf message. Let me know if you have any problems.

It was tested by the seller by placing in the NMEA mode and left it in NMEA mode. Now the board he used to talk to it has failed so he cannot change it back. After I could not get it to work I tried draining the battery down to .07 volts. I still could not get it to work in the Z3801 Put the old 6 channel back in and it works again http://gps.garlickfamily.org Can anyone tell me how to get it out of NMEA and back to binary?
