Wegener UNITY 4600 User manual

www.wegener.com 800032-02 Rev. G 1
General Information
If equipped with a receiver card, the Unity 4600 receives an L-band RF carrier from an external LNB,
demodulates the carrier, and then extracts the MPEG transport stream. If equipped with an ASI
transport card, it decodes the ASI line code and extracts the resulting transport stream. In both cases, if
conditional access has been applied, the Unity 4600 then descrambles the transport stream (or
individual programs) if authorized. It then supplies that stream to the DVB-ASI output (with program
mapping, if enabled). It also may decompress a selected program to provide composite video and two
stereo-audio outputs. (The compressed audio formats may be MPEG or Dolby AC-3.)
This guide provides information for setup and initial operation of the Unity 4600. For a full description of
refer to the Unity 4600 User's Reference Manual (p/n 800032-01) available on the worldwide web at
www.wegener.com.
Unpacking and Inspection
The box containing the unit should include:
Carefully unpack the items and inspect for obvious signs of physical damage that might have occurred
during shipment. Any damage claims must be reported to the carrier immediately. Be sure to check the
package contents carefully for important documents and materials.
Note: Save the original packing materials and shipping containers in case the unit must be returned
for repair. Packing the unit in another container in such a way that the unit is damaged will void
the warranty.

Warnings
To avoid damage to this and other equipment, or personal injury, the following items should be strictly
observed.
Elevated Operating Ambient
When equipment is installed in a closed or multi-unit rack assembly, the operating ambient of the rack
environment may be greater than the room ambient. Therefore, consideration should be given to the
ambient air temperature within the rack, and not just inside the room, when deciding if the maximum
recommended ambient operating temperature (TMRA) is being met.
Reduced Air Flow
Equipment should be installed such that airflow required for safe operation of the equipment is not
compromised. The Unity 4600 may be arranged in a rack without empty space between units if heat
rise is prevented by ensuring its side vents remain unblocked with adequate clearance around the vent
holes.
Mechanical Loading
Mounting of the equipment in a rack should be such that a hazardous condition is not produced by
uneven loading. This unit is not very heavy, but total rack loading must be considered. Also, do not rest
any unsupported equipment on your Unity 4600.
Circuit Overloading
Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of circuits could have on overcurrent protection and supply wiring. Ensure that the total
rack or breaker power consumption does not exceed the limits of the AC branch circuit. Appropriate
consideration of equipment ratings should be used when addressing this concern.
Reliable Earthing
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the branch circuit (use of power strips,
chassis ground lugs, etc.).
Rack Installation
When installed in an equipment rack, it is best that the Unity 4600 be supported by angle brackets or
cross supports. These should be screwed or bolted securely to the equipment rack, and be capable of
supporting the unit and its connecting cables. Do NOT install the unit if you have doubts about the unit
being safely supported. There are also four holes in the front brackets which are designed to accept
anchoring screws. It is essential that these brackets be used so the unit cannot be moved forward and
fall from the rack. It is always best to install the angle brackets or cross-members before setting the unit
in place. Then, prior to installing cables, put anchored screws or bolts-and-nuts into place on the front
brackets. Failure to do this can lead to pushing the unit out the front of the rack in later steps.
WARNING: FCC-Mandated Suppression of Radio Frequency Emissions
This is a Class A product. In a domestic environment this product may cause radio
interference for which the user may need to take mitigating action.
If the Ethernet port has a cable connected to it, that cable must be properly shielded
and grounded to minimize RF emissions that could interfere with nearby equipment.

User Interface
In operation, the Unity 4600 Home screen appears on the LCD as shown in Figure 5 (if using an L-band
receiver card with 4-way RF switching input - consult the online User's Manual if using an ASI input
option):
Figure 5: Unity 4600 Home Screen
Where pp...pp is either, in order of priority (and as available): (1) the first eight characters of the user-
supplied Channel Label; or (2) the first eight characters of the Program's Service Descriptor; or (3)
Progr xx (for Program # 'xx'), or PID xxxx (for video PID 'xxxx', where 'xxxx' is in hexadecimal notation).
fffff.ff is the downlink frequency in MHz. y is the selected RF feed port number and the MM…MM field is
a marquee. The MM…MM marquee alternates between messages indicating RF signal level (0 to 100
where 100 is max power and 0 is min), Eb/No (if locked on a carrier), or others indicating unit state or
the presence of faults. Note that the flashing arrow at the lower right of the display is a prompt indicating
that the user may find other menu screens by pressing the right or left arrow buttons on the front panel.

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.
