current date. Refer to Appendix I: Word List (See Page 125.) for the
command numbers for each part of the clock/calendar functions. Write out
the planned numbers to be entered before beginning. Use the worksheets in
Appendix H: Setup Worksheets (See Page 117.) to plan and record
programming to be entered into the VRC2000.
Telephone Interface
Several options make the VRC2000 work correctly with particular telephone
systems: pulse/tone selection, ring count, inactivity timer and precision dial-
tone waiting.
Pulse/Tone Selection
This option allows selection of DTMF or pulse dialing for VRC2000
outbound calling.
Ring Count
This option allows the VRC2000 to be programmed to answer incoming
calls after a certain number of rings. For example, if the ring count is set to
0, the unit is constantly online, allowing use of the VRC2000 with a
dedicated four-wire connection. (Such a dedicated four-wire connection will
provide 24-hour access to the site.) Unless using such a dedicated four-wire
system, program the unit to answer on the first or second ring.
Inactivity Timer
This option allows an inactivity timer to be switched ON or OFF. When the
inactivity timer is ON, the VRC2000 must receive at least one valid DTMF
command every five minutes, or it will automatically exit the setup, user and/
or operator modes. If the inactivity timer is OFF, the unit will exit the setup,
user and/or operator mode after one hour if it has not received any valid
DTMF commands; it will exit the user mode only when the you properly
sign off or hang up the telephone line.
Unless using the VRC2000 on a dedicated telephone line (for constant access
to commands), Gentner Communications recommends leaving the inactivity
timer ON.
Dial-Tone Wait
This allows the VRC2000 to be programmed to wait for a precision dial tone
before beginning to dial an outbound number. Some older telephone
systems, or some systems with poor quality lines, do not have reliable
precision dial tone. In such cases, the VRC2000 can be programmed to wait
six seconds before beginning to dial an outbound number.
Unless you are in an area with a very old telephone system, or an area with
very poor quality lines, Gentner Communications recommends programming
the VRC2000 to wait for a precision dial tone before dialing.
Telephone Interface Setting Exercise
In the following exercise, program the VRC2000 to make outbound calls
with pulse dialing, answer automatically after two rings, enable the inactivity
timer and enable dial-tone wait function.
