Becky, I have a Raven 660 and run it with a Ipaq hooked up to a trimble reciever. Farmworks controls it without changing anything except in the raven. Trig=1, dlog=off, baud=1200 and unit=sec. Everything else remains the same. Dlog could be on if you wish to record the amounts you are applying and units could be set to feet. Which ever you prefer. I have the stop bit set at 1 for the GPS reciever. I run on rev j in granular mode on farmworks but I had to have FWVRA 7.1 to make my 660 compatable. version 6.8 wouldn't run. I check my maps that I make in the spreader just setting out front of our office. I just set the default to different amounts and tap go and as long as it changes for each map then I know it is a good map. Just don't forget to chage the default setting back to where it should be.
