RF ON/OFF
Switches the transmitter RF output between standby (STBY) and
transmit (XMIT) conditions. In STBY, the RF output is zero.
BRIGHTNESS
Sets the display brightness to high (H), low (L), or automatic
(A; light sensing).

STBY
Indicates the HDX-1100 is in standby mode
(No RF output; unit is powered but not transmitting).
XMIT
Indicates the HDX-1100 is in transmit mode.
DC OK
Indicates DC Power is applied to the Remote Control Panel and
transmitting.
FAULT
Indicates an error condition in the HDX-1100 transmitter.
HI
Indicates the HDX-1100 is in high RF output mode.
LO
Indicates the HDX-1100 is in low RF output mode.
ENCRYPTION
Indicates the HDX-1100 is transmitting an encrypted signal
VIDEO
Indicates the presence of a video signal at the HDX input

Use a 9-pin RS-232 null-modem cable to connect the communication path between the RCU
and the HDX-1100.
A receptacle at the rear of the controller supplies DC power to the RCU. Vislink provides the
2-pin Weidmuller connector (Part # 52104-2) to connect to the power receptacle at the rear of
the controller. The required power range is from +10—+50 Vdc (negative ground only).
NOTE: During initial power up, the RCU will display a C until the HDX-1100 processor
completes a boot up and self check sequence; this is normal. If the C does not disappear
within one to two minutes, the HDX-1100 has lost power or a communications error has
occurred; check the circuit breakers, and power and serial cable connections.
To facilitate updating or servicing an HDX-1100 transmitter, we recommend that the
transmitter and RCU panel are fed from different circuit breakers. In normal operation, power
should be applied to the RCU first, or to both units simultaneously. To use local (front panel)
control of the HDX-1100 transmitter, the RCU should be off (not powered) when the
transmitter is first powered up. The RCU always has priority, and will assume control if power
is applied while the transmitter is on and in local control mode. At the same time, the front
panel will freeze and be non-responsive even though the RCU is functioning perfectly. To
return to local control, turn both units off, and re-boot only the transmitter.
