* Where LNB DC is supplied on RF center pins this header is not included. When four RF inputs are supplied without
this header, LNB DC is supplied on center pin of Port 4. Note that Compel network can lock LNB DC to OFF.
** After plugging in headphones, the unit immediately displays a screen prompting the user to select the Audio Port to
be monitored.
Danger
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 (T
MRA
) is being met.
Reduced Air Flow
Equipment should be installed such that airflow required for safe operation of the equipment is not compromised. The U4650 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 U4650.
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 U4650 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.
User Interface
In operation, the U4650 Home screen appears on the LCD as shown here
(valid 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):
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.
