Hardware
AC Current Sensor
This accessory allows you to accurately measure current samples from AC
power lines. Use the AC Current Sensor to check the status of tower lights,
incoming AC power or the power output of your standby power generator.
The AC Current Sensor provides an analog output which you can connect to
a VRC2000 metering-channel input. Gentner Part Number: 910-093-001
Command Relay Unit
The standard VRC2000 remote control unit provides open collectors for all
command channel outputs. This accessory converts the open collectors to
relay contact closures with Phoenix® connectors. Each relay is rated at 5A,
up to 240V, noninductive. One Command Relay Unit will interface with
eight VRC2000 command channels. Gentner Part Number: 910-085-120
Data Interface
The Data Interface includes a 2,400 bits per second (bps) internal modem
plus a 2,400 bps RS232 serial communications port. This accessory allows
you to communicate directly with the VRC2000 through a PC running Setup
VRC2000 software (in the terminal mode) or VRC-Win software. You can
make this connection directly using the RS232 port or over standard
telephone lines through a modem. Gentner Part Number: 910-076-201
Silence Sensor
Absolute carrier control is required by the FCC when the VRC2000 is used
as the primary remote control system for a transmitter and is accessed via the
telephone network. The Silence Sensor gives you absolute carrier control by
monitoring the program audio feed to the transmitter.
Gentner Part Number: 910-074-001
Telephone Surge Protector
The VRC2000 comes equipped with the VRC2000 Telephone Surge
Protector. You may want to order a spare Telephone Surge Protector in case
the original unit is damaged by a lightning strike or other voltage surges.
Gentner Part Number: 910-072-050; 900-072-050 (Parts Kit)
Temperature Sensor
The Temperature Sensor can be directly interfaced with the VRC2000 to
allow you to monitor the internal environment of your transmitter building,
the outside temperature, the temperature inside your equipment rack, or even
the temperature at the top of the tower. Use it to automatically turn on
de-icing equipment or sound an alarm due to overheating. The Temperature
Sensor accurately measures up to four temperatures simultaneously over a
range of -50–250° F. The unit is available in either Fahrenheit or Celsius
versions. The Temperature Sensor Unit comes equipped with Temperature
Probe with a 12-foot cable. Gentner Part Number: 910-091-001
(Temperature Sensor plus one Fahrenheit probe); 910-091-003 (Temperature
Sensor plus one Celsius probe)
Temperature Probe
You can connect up to four Temperature Probes to the Temperature Sensor
Unit. Each Temperature Sensor Unit comes equipped with one Temperature
Probe. Gentner Part Number: 910-091-001 (Fahrenheit probe);
910-093-001 (Celsius probe)
