Plus and Minus Reversed

Hi Guys, could you please help me with this problem. I have a Mach 3 Mill with a Mpg Pendant that I hooked up. When I use the Mpg pendant and move in minus the machine moves in plus, this happens in all axises. I am sure it is some setting in Mach 3, but am just not sure where to find it. The pendant is a usb standard they sell on ebay for $160. Arturo Duncan sells them. Thanks alot, Pat

If you jog with the keyboard, does it move in the correct direction, or the same as the mpg?

Thanks Gerry for your input. Arturo got back with me, and his solution worked.
In the Mach3 config pins and ports the #1mpg a pin and a port was 2 and 2. Pin b was 2 and b port was 3. Arturo said to reverse them. And it worked. Thanks, Pat
