I have a hagie with a raven 4600 with serial port and about version 11.34 loaded onto a fujitsu tablet computer, that I use to paint the field as I spray, have used this sytem in a coupe and other tractors for several years with an IFB switch. In the coupe I could only do the whole boom or nothing, I have the hagie set up this way now as well. I have been told that I can paint boom section at a time if I have the serial port in the raven which it does. So I am wondering if I need a newer version of software to do this, I also purchased a 20/20 monitor this spring which seems to have included some farmworks software as well, which I wonder if I could use for this application if needed. Also what is the specific cabling needed to do this, the fujitsu has a 9 pin connection as well as pcma card port with adapter to 9 pin as well. Then if I get that far, where do you go to set up the boom sections in the software on the fujitsu???
