When used with a GSC3000, the Voice Interface is an optional unit that provides dial-up telephone access to
your site. In a VRC2500, the Voice Interface unit is integrated with the system, but is still shown as a separate
unit in the Lynx software. The Voice Interface is configured using the Lynx software. For descriptions of each
Voice Interface configuration option, refer to Chapter 4. Hardware connections are detailed below, and the rest
of this chapter is dedicated to Voice Interface operation.
For a condensed list of DTMF (touch-tone) codes used to operate the Voice Interface, refer to the Voice
Interface Code Reference at the end of this chapter.
GSC3000 HARDWARE CONNECTIONS
All that is required to hook up the VRC2500 to a telephone line is connecting a line cord to the LINE
connector on the rear panel of the VRC2500.
The Voice Interface can be used for telephone access only, or you can pair it with a dial-up modem for both
voice and computer access to your site. See Chapter 6 for configuring the recommended dial-up modem.
To connect your Voice Interface to voice and data lines:
1. If it is not already linked, connect the Voice Interface to an I/O unit using the G-Bus ports and the
included G-Bus cable. Because the Voice Interface is always identified as unit 16, you do not need to edit
the Voice Interface unit number before connecting it to I/O units.
2. Plug the RJ-11 line cord from the wall
jack into the LINE jack on the Voice
Interface. If you want to make a data
connection through your Voice
Interface, connect the SET/MODEM
jack on the Voice Interface to the LINE
IN jack on your external modem. Use
the supplied DB9-25 straight-through
serial cable to plug the modem into
COM1 on the Voice Interface.
