Ethernet Status LEDs (rear panel)

The Ethernet jack has two LEDs which provide the following indications:

LAN

–

Green

LED: On if active LAN connection detected. OFF otherwise.

ACT

–

Ye llo w

LED: Flashing ON if ethernet packets are output or addressed

packets are input. OFF otherwise.

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”.

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 - alternat-

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