I have one of the monitors in my 1998 2366. Got it new to me two years ago.
I learned to download the SRAM card everynight or I'd lose data.
Also learned that the darn think was not Y2K compatible. Kept having problems the first year with no data, incomplete data, etc... Had an "expert-that works with/sells Ag Leader stuff" help me out. Finally punched in a year date of ten (10) earlier and it's worked fine ever since. So for last year's data, my printouts say 1998 instead of 2008. So this year's harvest will be 1999, next will be 1990.
I have two cards.
The expert gave me the software from Ag Leader to put on my computer. You get either 15 or 30 days of free use then it locks you out of doing much with the data--like printing maps.
After the 15 or 30 period, you can still download the data into your computer and see the data points and a really small map of your field in the bottom left corner of the computer screen. But you can't do anything with it unless you pay Ag Leader a bunch of $. I finish harvest and take my data to the coop and they will print it out for a dollar a page.
The coop gave me another software disk last year. So after harvest this year, I will load the software and print the maps right then on my main computer. I will use the previous software on an older computer laptop to save the data each night. I save the data to a thumb drive and transfere it to the main computer.
Oh, make sure your computer will read a SRAM card. Our newer laptop does not and neither does our main computer. But our old sitting on the shelf for a couple of years does. The power supply "broke" for it. Had to buy another off of ebay-it was cheap. Almost purchased another identical laptop.
I set mine to read data either every 2 or 3 seconds. I calibrate at the beginning of harvest. I don't need the exact bushels during harvest since more than half gets measured by the elevator and the rest by measuring the bins when finished.
I start harvest, calibrate and continue. After harvest, I add my scale tickets up and add the bin amounts up, add together then compare that number to the yield monitor.
First of all the acres will be off in some fields, nearly dead on in some others. So I adjust the field by field numbers and adjust the final overall numbers (which the coop did for me last year-I plan to this year).
I figure this gives me a "relative" bu/ac printout. Good enough for me, I farm by my self, I know my fields, landlords do not need the info (for now).
Hope this helps.
