Table 3.2: Front-Panel LED Indicator Descriptions

Indicator Label

 

Color and State*

Meaning

 

 

 

 

CUE

 

GREEN constant

A user cue relay is closed (energized).

 

 

 

 

 

 

GREEN flutter

During a user relay “pulse” activation on any relay.

 

 

 

 

 

 

Off

All user cue relays are open (de-energized).

 

 

 

 

ALARM

 

RED constant

One or more current alarm indications.

 

 

 

 

 

 

RED blink

An alarm event has occurred in the past and has not been

 

 

 

 

acknowledged and cleared by the user. Note that this state may

 

 

 

 

exist together with a current alarm (RED constant). In that case, the

 

 

 

 

blink state is defined as quickly cycling OFF-ON-OFF (~100ms

 

 

 

 

each) approximately every 2 seconds.

 

 

 

 

 

 

Off

No alarm condition currently exists.

 

 

 

 

AUTH

 

GREEN constant

Unit has transport MPEG sync and the stream is not scrambled (in

 

 

 

 

the clear). Streams that are “clear” are always presumed to be

 

 

 

 

“authorized”.

 

 

 

 

OR:

 

 

 

 

Unit is authorized for current scrambled transport stream (or

 

 

 

 

selected program) and has transport MPEG sync. When using

 

 

 

 

Wegener CA (’97 Version), being “authorized” means being

 

 

 

 

addressed with current and valid ciphered keystream messages. In

 

 

 

 

a PIN system, if the transport stream is scrambled, and the unit has

 

 

 

 

been programmed with any key other than the null ‘00000’, then it

 

 

 

 

presumes that it is “authorized”.

 

 

 

 

 

 

GREEN flutter

Unit has successfully deciphered a valid descrambling seed in the

 

 

 

 

last five seconds. Normal behavior in functioning CA system.

 

 

 

 

 

 

Off

Unit has transport sync, the transport stream is scrambled, and the

 

 

 

 

unit is NOT authorized. Also OFF if no transport sync.* LED states

 

 

 

 

are defined as follows: Blink - alternating ON for ~100ms and OFF

 

 

 

 

for ~2 seconds; Flash - alternating ON for ~500ms and OFF for

 

 

 

 

~500ms. Flutter - like flash but with shorter ~100ms ON and OFF

 

 

 

 

times.

 

 

 

* LED states are defined as follows: Blink - alternating ON for ~100ms and OFF for ~2 seconds; Flash - alternating ON

for ~500ms and OFF for ~500ms. Flutter - like flash but with shorter ~100ms ON and OFF times.

 

 

 

 

Rear-Panel

The U4600 also has two LED (light-emitting diode) indicators on the rear panel. They pro-

LEDs

vide the following indications:

 

LAN

Green LED: ON if active LAN connection detected. OFF otherwise.

Front Panel Audio Monitor

ACT Yellow LED: Flashing ON if ethernet packets are output or addressed packets are input. OFF otherwise.

To monitor audio output from the front panel, insert a 1/4-inch stereo phone plug into the audio monitor port. The U4600 will detect the phone plug and immediately display the Audio FP (front-panel) Monitor Selection screen. This second-level menu screen allows the user to select and monitor the desired audio stream. After two minutes without a keypress from the front panel, the U4600 will revert to the default LCD screen.
