Hi Graham,

Hi,

Would someone please be so kind as to explain the precise difference between the two protocols GS232A and GS232B?

I am missing something obvious I expect but..

If you get an answer direct, would you please send it me also?

thanks

Hey Graham--

Here are the manuals:

http://polysat.calpoly.edu/earthstation/documents/gs-232a.pdf http://polysat.calpoly.edu/earthstation/documents/gs-232b.pdf

The A version has trim pots for calibration, and the B version has a PIC18 inside with a digipot for calibration. -- Bryan Klofas, KF6ZEO
