3. One-Net Hardware and Setup
3.1. Introduction
The One-Net is a 2U rack mounted unit built with the latest digital PC computer
technology. It is an embedded PC platform. The front of the One-Net, pictured
below, provides a very simple face for a very sophisticated platform. The One-Net
exposes the PC motherboard connectors and single PCI slot in the rear of the unit.
3.2. Front Panel
The front panel features a 2x20 character backlit LCD that indicates power-on, and
real-time device status. There are also two LED’s - one red, one green - for
indicating specific types of status. The select switch provides the ability to activate a
Required Weekly Test from the front panel. A front panel speaker allows the user to
verify the quality of audio signals.
3.2.1. LCD
The backlit green LCD provides real-time status of the One-Net. The LCD is
used for numerous purposes, all indicating system and/or encoding/ decoding
and active alert status. Here is a list of information available from the LCD.
•
When the One-Net is powered on, the LCD will light up, indicating
power-on state.
•
While the One-Net is booting, the LCD will move through a few display
states, eventually arriving at the ready state where the first line will
display
One-Net: ON followed by a crawling display showing the
programmed unit name, the software version number and the IP address.
•
During decoding of an incoming alert, the LCD will display information
about the source and the stage of the decoding.
While decoded, forwarded or originated alerts are active on the One-Net, the
top line will repeat displaying pertinent identification for each active alert.
