Serial Numbers Higher than 380

Interfacing PI-963 & HU-961
(Serial Number higher than 380)

When interfacing the PI-963 with the HU-961 with a serial number higher than 380, there is a jumper inside the HU-961 that needs to be changed. You will need to remove the top of the HU-961 and as you are facing the unit, this small black computer jumper strap is in the right rear corner on the right hand side of the I/O Connector and in front of a small blue capacitor. The jumper will be on the two left pins or two inner pins. It needs to be moved to the two right pins or two outside pins.
