Power & Data
Power is supplied to the unit via the male XLR4 socket on the underside. 12 - 16 volts
DC. The unit generates RS485 data which is output on the XLR3 socket. The cable
length for the RS485 output can be up to 1km using good quality balanced cable for
the data pair.
Tally Inputs
Tally inputs are provided which can be triggered by contact closure (switch or relay)
or by connecting the appropriate pin to GND (pin 9) with an 'open collector' circuit.
The 9pin Dsub connects both the tally inputs and also the 'touch down' outputs.
Holding the appropriate tally pin to GND will generate a 'Tally On' command to the
camera. Removing the GND generates a 'Tally Off' command to the camera. A 'tell-
tale' red indicator will illuminate on the panel.
Monitor Switching
Also on this 9pin Dsub are open collector to GND outputs for monitor switching.
Operating the Touch Down switch will ground the pin associated with the selected
camera. Use pin 9 for GND connection.
A green indicator will illuminate on the panel when the touch-down is held.
Multiple Panels
Multiple panels can be cascaded using the Hirose 4pin connector. Both power and
data are distributed via this connector. Connect power to panel 1, then using a Hirose
to XLR cable connect to panels 2, 3, 4 etc. All the data finally appears on the output
of the last panel in the cascade.
