The JPAN connector can be used to connect the Accessory 16 (Control Panel), or customer-provided I/O, to the 
PMAC, providing manual control of PMAC functions via simple toggle switches. If the automatic control panel 
input functions are disabled (I2=1), the inputs become general-purpose TTL inputs, and the coordinate system 
(C.S.) specific outputs pertain to the host-addressed coordinate system.
