RS232 is good for hundreds of feet, easily at 9600 baud. I have run 1000ft cat 5 spools without issues and I've hooked a scope up to look at the data signals, even at 1000ft, there was still 50% margin on the data timing

RS232, might be very, very old, but it still, both in cost and performance is the lowest cost, highest performance interconnection wired technology available.

I get pressured all the time in designs to go USB ... USB is fine, as long as you don't mind being limited to 3 meters, the chips cost about 5x more than RS232 and its VERY expensive to have isolated USB, where in RS232, its about 20 cents in parts.

Needless too say my next design ( in progress ) will still have RS232



Mikes install is in a PACKED to the rafters garage, I'm surprised he even found space to mount the GT, on the west wall, which itself get heated by the sun. Even in these conditions, the GT3.8, didn't derate. mikes fan does help but isn't required.

The Derating chart is very conservative ... the ONLY way I have be able to get a unit to derate was to cover it in towels, at full power, it final said uncle after 2 hours .. this was for testing of course. Hands down, bar none, its the best inverter thermally on the market.



It's a tab delimted file and GT-View intentional uses the .xls extention so double clicking the log file will open excel in a windows pc with excel installed. Excel by default will automatically use the tabs and columize the data, no manual importing is necessary. One can always right mouse click and use open-with and use your favorite tex editor, like word pad for viewing

What a tease. Can us give any more hints, or are you going to let us hang?

???? Only for some folks. I have to re-name my files to .CSV, which then forces excel to IMPORT them as the text files they are.


I am using Excel 2002; I would hazard a guess you are using an older version of Excel - which is not letting you bring the file in "automatically". What happens when you click on the "ASCII".xls file?

Another ( and maybe confuseing) cable "standard"
is here

But this is more specificly for interchangeable cables for computers & modems. The GT uses a very simple cable, and works well with it.
