Wire per crosspoint remote control:
This option is made available by way of connections on the rear of the pushbutton control board and is therefore
only available at the switcher if a local control set of buttons is fitted.
It is not necessary for the buttons to be functional.
A connection is made from PL 3 - 16 pin HE14 type connector to pins on the PL 4 connector.

20 x 1 Operation:
Due to the number of connections required, it is not possible to operate the switcher in 20 x 1 wire per crosspoint
mode and retain the standard BCD remote control.
For 20 x 1 operation it is necessary to wire connections from the back of each PL 3 connector, on the rear of the
two halves of the control panel, to the PL 4 connector on the rear of the switcher.
Before doing this, the existing connections to PL 4 should be removed.
PL 3 Wire per crosspoint control input: (On rear of each of two pushbutton panels.)
(Recommended wiring to PL 4 on rear panel.)
