SYSTEM OVERVIEW
GSC3000 Hardware Components
The central component of a GSC3000 system is the I/O (input/output) unit, labeled I/O 8 or I/O 16
depending on the number of available metering, status and command channels. The I/O unit physically controls
your command outputs and receives metering and status inputs. Alarm settings, programmed commands,
calibration and all other setup and configuration data are stored on the I/O unit. Up to sixteen I/O units may be
networked to expand your channel capacity at any location to a maximum of 256 channels of metering, status
and command.
Note: Regardless of the number of I/O units at your location, the installation is considered one GSC3000 system, or
a single site. A site simply refers to an independently linked group of one or more I/O units.
A GSC3000 system may also contain a Voice Interface. This optional hardware allows dial-up voice control and
monitoring of your remote site, dial-out alarm notification, as well as the audio input/output functions described
in Chapter 11.
To network multiple I/O units (up to sixteen) and connect a Voice Interface at your site, each I/O unit and Voice
Interface ships with a 14” RS-485 cable with RJ-45 connectors. This cable connects one unit to the next to allow
bi-directional data flow over a high-speed digital bus (called the G-Bus). Instructions for making the G-Bus
connections are in Chapter 2.
VRC2500 Hardware Components
The VRC2500 contains two hardware components in a single two rack-unit chassis: the I/O (input/output) unit
and the Voice Interface. Like the GSC3000, the I/O component physically controls your command outputs and
receives metering and status inputs. Alarm settings, programmed commands (macros) calibration and all other
setup and configuration data are stored on the I/O unit. The Voice Interface is built into the VRC2500 to
provide monitoring and control access from any touch-tone phone, as well as alarm reporting and audio
input/output functions. See Chapter 11 for more on the Voice Interface component of the VRC2500.
Note: When you set up and control your sites using the included Lynx software (see below), you will notice that Lynx
identifies the VRC2500 I/O and Voice Interface components separately, as two different units. It is important to
remember that even though the VRC2500 is a single system, the I/O and Voice Interface are set up individually
during the configuration process, and they use separate firmware files.
Lynx Software
The Lynx software package you received with your system provides easy setup, monitoring and control from any
PC. Channel labels, limits, alarms, scheduled actions, and setup information is entered directly from your
computer and then saved to the I/O unit. After configuration is complete, the system can run without a
dedicated PC connection. However, a computer connection allows convenient control and monitoring of your site
equipment, as well as the ability to automatically log data at your site.
You can connect your PC to a GSC3000 or VRC2500 site via dial-up and dedicated telephone lines, radio links
(RF), or a direct serial port connection. When you set up your site in Lynx, you will specify a primary and backup
connection method. If the primary connection fails, Lynx will activate the backup connection and provide on-
screen notification that the backup connection is in use.
Available connection methods are:
D Diirre ecctt A direct connection can be a null modem cable connection between the PC serial port the
remote control unit or a full-time (leased-line) modem connection, RF link, or another
connection type that requires no dialing.
