WVRC-4 Plus Installation and Operation Manual
INSTALLATION
Connecting your WVRC-4 Plus to external equipment.
Chassis Ground screw (Chs Gnd)
This 6-32 screw MUST be connected via a to the station/site ground system for the
proper operation of this equipment.
Power Failure Input
Connect a user supplied 6 to 12 volt DC only power source (center positive) to the
power failure input labeled PF. The barrel connector size is 2.1mm ID x 5.5mm OD.
A 6 to 12 volts DC wall transformer of any current of 10 ma or more will power this
input.
NOTE:
The primary (120vac) of the power failure wall transformer should be con-
nected to the utility company side of your service. An UPS is suggested to power
the WVRC-4 Plus during power outages.
NETWORK connector
Connect one end of the supplied CAT5 (straight or x-over) cable to the desired ETH-
ERNET (WAN/LAN) port.
Silence Sensor Inputs
Connect your unbalanced monaural or stereo audio source to the terminals labeled
SS LT, SS GD and SS RT. The nominal input level is between be between -10 and
+24 dBu. The input impedance is approximately 22K ohms. When the SS LT and/or
SS RT input has audio applied and the silence sensor function is activated the front
panel SS LED will illuminate. If the SS LED is out, the audio level is not present
or too low and if it’s flashing, it is in an alarm condition (if enabled).
Metering (analog) inputs
CAUTION!
Metering (analog) input samples may be elevated several hundred
volts above ground on some external equipment. Permanent damage may occur to
the WVRC-4 Plus and/or external equipment if a high voltage source is connected
to the WVRC-4 Plus! Failure to observe this warning may also cause injury to the
installer or other personnel.
CAUTION! DO NOT CONNECT SAMPLE VOLT-
AGES IN EXCESS OF POSITIVE 10 Volts DC OR DAMAGE MAY OCCUR
TO YOUR WVRC-4 Plus.
