Second High Limit This is the highest tolerance limit the metering channel will monitor. See also
Tolerance Limits.
Second Low Limit This is the lowest tolerance limit the metering channel will monitor. See also
Tolerance Limits.
Security Levels The VRC2000 provides three security levels: operator, user and system. Operator
access allows metering and status-channel readings to be taken. User access allows
metering and status-channel readings to be taken; commands can be issued, and
alarms can be cleared. System access allows setup of any metering/status/command
channel, changing of VRC2000 programming and access codes; commands cannot
be issued, and readings from status and metering-channel inputs cannot be taken.
Sequence-Output ProgramsThe VRC2000 allows up to four separate sequences of up to 32 keystrokes (DTMF
commands) to be programmed. These mini programs are stored in the unit and can
be triggered with DTMF commands.
Setup VRC2000 Software This software is an easy-to-use DOS software package. See Appendix C:
Accessories (Page 100).
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 telephone line.
The Silence Sensor provides absolute carrier control. See Appendix C: Accessories
(Page 100).
Single-Response Reports A single-response report is where the VRC2000 sends only a single response to
report the readings coming from a status or metering channel. See also Multiple-
Response Reports.
Sound Sensor The VRC2000 comes with a built-in condenser microphone built into its front
panel. This microphone can be activated at any time to listen to sounds being
generated in the vicinity of the VRC2000.
Status Channels The VRC2000 has 16 status-channel inputs, each of which can be high (open) or
low (closed). The VRC2000 can be programmed with desired words to describe the
information gathered from a status channel.
System Access Code The system access code allows setup of any metering/status/command channel,
changing of VRC2000 programming and access codes; commands cannot be issued,
and readings from status and metering-channel inputs cannot be taken.
System Identifier The 20-word statement a VRC2000 makes when a user signs onto the system can be
customized to suit application needs.
Telephone Interface Several options are available to make the VRC2000 function with your particular
telephone system. Options include selection of pulse/DTMF dialing, ring count,
inactivity timer and dial-tone wait. See also Ring Count, Inactivity Timer, Dial-
Tone Wait.
Telephone Surge Protector This accessory comes as part of the VRC2000 system, although additional are
suggested for replacement of others damaged by lightning strikes, etc. See
Appendix C: Accessories (Page 100).
Temperature Probe Up to four temperature probes can be connected to the Temperature Sensor
accessory. See Appendix C: Accessories (Page 100).
Temperature Sensor Unit See Temperature Probe.
