Individual tally outputs:
If a switch panel is not fitted, the 803089 tally decoder may be fitted externally to the switcher. Note that the
803089 tally decoder requires 12 Vdc to be supplied by the switcher. It can therefore only be connected to PL 4 on
the switcher rear panel.
The individual tally output option is made available by way of logic on the pushbutton control board and is
therefore only available at the switcher if a local control set of buttons is fitted.
A connection is made from PL 7 - 16 pin HE14 type connector to pins on the PL 5 connector.
10 x 1 Operation:
PL 7 Individual tally outputs: (On rear of pushbutton panel.)
(Recommended wiring to PL 5 on rear panel.)
PL 7 - HE14
PL 5 - 25 pin 'D'

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 7 connector, on the rear of the
two halves of the control panel, to the PL 5 connector on the rear of the switcher.
Before doing this, the existing connections to PL 5 should be removed.
PL 7 Individual tally outputs: (On rear of each of two pushbutton panels.)
(Recommended wiring to PL 5 on rear panel.)
