The user interface consists of 20 front-panel multi-color LEDs, a pushbutton, and an Ethernet port.
The LEDs provide basic GARD 8000 event information and can be configured by an operator using
the browser interface. The LED labels can be changed to suit the application. The pushbutton is a
programmable function typically used to reset the front panel LEDs.
The Ethernet port allows the user to configure the system modules. The front port is for temporary
connection to a portable computer, while the rear ports are intended to be permanently connected to
external equipment.
The base 8-Bit TPS module (500410) is a four-channel, eight function digital teleprotection
system. Refer to Section 9 for more information on Teleprotection.
The 96-Bit TPS module (500410-1) is a single channel, ninety six function digital
teleprotection system.
There is also an RS-449 / X.21 / V.35 interface on the module. There is a 37-pin connector for this
interface located on the Power Supply I/O module rear panel, at the rear of the GARD 8000 chassis.
This can be seen near the top of Figure 6-23. An optional G.703 digital interface utilizing a 15-pin
connector is also available in place of the above (See Figure 6-24).
