LED Indicators
Eight light-emitting diodes (LEDs) provide status information about your
Unity 4600
and its processes
as listed in
Table 2
.
Table 2:
Unity 4600 LED Indicators
Indicator
Color and State
Description
CARRIER
GREEN constant
Unit has demod and FEC lock on the RF carrier
Off
Unit does not have demod and FEC lock on the RF carrier
TRANSPORT
GREEN constant
Unit recognizes a valid transport stream
Off
Unit does not recognize a valid transport stream
COMPEL
GREEN constant
COMPEL control stream received within last two minutes
(including keep-alives) while locked continuously on the
current transport stream for >2 minutes
GREEN flash
Unit has had a verified transport stream for >2 minutes and
COMPEL is required but no valid COMPEL
GREEN flutter
COMPEL has been addressed to unit within last 5 seconds
(excluding keep-alives).
Off
Otherwise. Note that this LED must be OFF when there is no
valid Transport stream OR COMPEL
SERVICES
GREEN constant
Unit is processing services for delivery.
Off
Unit is not processing services.
WARNING
YELLOW constant
One or more warning indications present - usually indicates a
problem with the incoming signal, a minor unit fault, a possible
impending failure, or that important information is available
Off
No warning conditions
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 the alarm
LED may also blink while on.
Off
No current alarm condition 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".
Off
Unit has transport sync, the transport stream is scrambled,
and the unit is NOT authorized. Also OFF if no transport sync.
