1.2.2 Status LED
The DASDEC II's two LEDS are used for a variety of status indications, making it easy to see the state of certain
important system information.
System Status - Green LED
 When the DASDEC II is first powered on, the green LED is dark.
 When the booting process advances far enough, the green LED begins to blink.
 When the DASDEC II nears a ready state, the green LED blinks more rapidly. When the DASDEC II is
ready, the green LED light is on solid. A solid green LED indicates the DASDEC II is operational.
 If the green LED starts blinking, the DASDEC II server has become non-operational. This can happen
during software restart or upgrades.
Alert status - Red LED
 When the DASDEC II is first powered on, the red LEDs are dark.
 After the DASDEC II becomes operational, in a ready state, with the green LED solid, the red LED
indicates decoding, alert sending status, and unacknowledged, unforwarded active decoded alerts.
 If the red LED is blinking quickly, with pauses, the DASDEC II server is decoding an incoming alert. If the
red LED is solid, the DASDEC II is sending an EAS alert. If the red LED is blinking slowly and regularly,
an active alert has been decoded and has not been forwarded or acknowledged. Alerts are
acknowledged by pressing the front panel button or by pushing the Acknowledge button for the alert on
the Web browser. If the red LED is blinking quickly and regularly, an active alert is being held pending
GPI 1 input closure.
1.3 Back Panel
The back of the DASDEC II provides all of the connection ports. In addition to the standard PS/2 mouse and keyboard
and VGA monitor ports, the DASDEC II provides an RS-232 serial port (COM1), two RJ45 LAN ports, four USB ports,
main audio line in, out, and microphone jacks, optional auxiliary audio line in, out, and microphone jacks, radio antenna
jacks, GPIO, and a TV video out connector. The DASDEC II provides software support for the TV out as a licensed option.
The optional second audio sound card likely also has an unused MIDI interface port.
