Hi, The MPG jog wheels I sell have differential outputs.
http://homanndesigns.com/store/index.php?main_page=index&cPath=15 That is A+, A-,B+,B-. The - outputs have the complement of the + signal on them. You can use them as single ended inputs by ignoring the A-, B- outputs and just use the A+, B+ outputs. Cheers, Peter.
