Rear-Panel
LEDs The U4600 also has two LED (light-emitting diode) indicators on the rear panel. They pro-
vide the following indications:
LAN Green LED: ON if active LAN connection detected. OFF otherwise.
ACT Yellow LED: Flashing ON if ethernet packets are output or addressed packets are
input. OFF otherwise.
Front Panel
Audio Monitor 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.
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.
