Connecting and Setting Up On/Off Sensors or Relay Controls (VR-4900 and KRF-V9993D), continued
The VR-4900 and KRF-V9993D supports 2 types of addi-
tional external controls:
• A relay control that enables you to operate external re-
lay-control devices (such as the Xantech 590-0 program-
mable controller, via Xantech’s 599-00 pulse switching
module).
• A TV ON/OFF sensor that enables you to use the Perfect
Macro feature (described further in the U
sers’ Guide ) to
accurately sense whether the TV is already on or off and
adjust accordingly.
To Connect Relay Controls:
1. Consult the relay control’s manual for compatibility in-
formation and installation instructions before connect-
ing it to your new receiver. If you install the control in-
correctly or connect an incompatible control to the re-
ceiver, you may damage the control
and your new re-
ceiver.
2. Connect the control cable to the receiver’s RELAY CON-
TROL jack. This jack supports a 12V, 20mA signal.
Do not connect multiple 599-00 switching modules to each
other or to the receiver, as this can exceed the maximum
current capacity of the jack and damage your receiver.
To Connect TV ON/OFF Sensors:
1. Connect the sensor to the TV as described in the sensor’s
manual.
2. Connect the sensor cable to the receiver’s TV ON/ OFF
SENSOR jack. This jack supports a 5V, 10mA signal.
JDS:PSS-TV or NILES:LS-1, APC-2 sensors are compatible
with your new receiver.
