Thank you sir .That's what I thought. If I may ask you a question . I have a cnc4pc C-22 pendant board plunged into port 2 . It only shows A & B phase connected to it . My mpg is a 6 pins A/A-B/B- 0V AND 5 V Im guessing I cant use this . And I need a Fanuc style thats A,B, 0V 5V..I noticed they say it only works with his MGP 2 ,3,4 I assume that means a 2,3 or 4, pin output of the manual pulse generator ? Thank you sir for providing all of us here your support . Thanks.
