PMAC Common
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.
