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

provides a very simple face for a very sophisticated platform. The One-Net

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

alert status. Here is a list of information available from the LCD.
 When the One-Net SE
is powered on, the LCD will light up, indicating power-on
state.
 While the One-Net SE
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.
