Connection
Be sure your modem is correctly installed in Windows and that it is properly functioning before connecting it to
your system. Note that a full-time modem needs to be connected to COM1 on a GSC3000 I/O unit or to the
FULL-TIME port on a VRC2500 – it cannot be connected to a Voice Interface.
To connect a full-time modem to your I/O unit:
1. The serial interface port on the back of the modem is a DB25 female connector. Use the provided serial
cable to connect the modem to your PC and your or VRC2500 or GSC3000 I/O. Always use COM1 on
the GSC3000 I/O unit, not COM2. Use the FULL-TIME port on the VRC2500, not DIRECT.
2. For a two-wire connection, plug one end of a two-wire phone cable into the LEASED jack on the modem
and connect the other end to your leased line wall jack or terminals, or to your communication link. For a
four-wire connection, plug one end of a four-wire phone cable into the LEASED jack on the modem and
connect the other end to your leased line wall jack or terminals, or to your communication link.
A typical four-wire phone cable with RJ-11 connectors is broken out as follows:
3. In order for the system to detect the newly installed modem, cycle the power on the unit.
Note: Always use a telephone line surge suppressor when connecting a modem or Voice interface to the RJ-11 wall
jack. Damage caused by voltage surges (including lightning strikes) is not covered by the factory warranty. Visit our
web site at www.burk.com or contact our sales department for information on suppressors we recommend.
