Haas jog pendant pinouts

Just refitted a haas cnc with new yaskawa drives and a centroid control panel all good so far managed to tune all drives and calibrate movement. Got a touch screen up and running only to find that the on screen jog panel does not work with this version of software, so l am using a standard keyboard with shortcuts. So thought l would adapt the old haas jog pendant to connect to the centroid mpg socket, got the centroid pinouts but cannot find the haas pendants pinouts anywhere on internet Haas site does not have any, emailed their support but don’t expect an answer. So does anyone know the pinouts or how to test the pendant with a meter to decipher which wire is which.
Many thanks
Carl
