General Information

• The HU-961 comes standard with Pin 3 as a dry contact closure to ground to allow the user to interface his own program interrupt switch.   When using HollyAnne's PI-963, by changing that jumper causes Pin 3 to have 9 volts on it when it goes low.  This is what we use to power up the PI-963. 

NOTE:   Refer to the Installation Instructions or online diagram for the PI-963 Router (Figure 7), for the wiring procedure.
