Unpacking And Mounting

The shipping carton contains the DSR-4410, two quick disconnect terminals, a power cord
and this Operator Guide.
The IRD should be installed in an Electronics Industry Association (EIA) compliant 19-
inch rack. It is recommended that the IRDs have 1RU spacing, above and below, for
airflow.

Connecting a Unit for L-Band Input

To Connect a Unit for a New DigiCipher II Service
First determine which satellite, transponder, Virtual Channel Table (VCT) number, virtual
channel, and audio mode (stereo, surround, mono, or dual mono) is to be used. Contact the
programmer for this system information so that the desired services can be received.
Connect the L-band inputs from the dish antenna and LNB. If LNB power is needed,
navigate to the appropriate menu and turn LNB power On. The default for LNB power is
Off.
• For a single polarity L-band satellite connection, connect the coax from the LNB (either
horizontal or vertical) to Port0 or Port1.
• For installations using both polarities of a satellite, connect one LNB coax to each port.
The polarity is programmable for the DSR-4410. The default polarity for Port0 is
Horizontal and Port1 is Vertical.
To view video and On-Screen Diagnostics during installation, connect the OSD Video
Output on the unit to a 75 ohm video monitor. To view video, connect the Video Output to
a channel modulator.
To listen to audio during installation, connect the audio outputs to a local amplifier and
speaker. A standard stereo system will suffice, but the lack of differential audio inputs may
make the audio seem degraded. After the unit is authorized and outputting the desired
service, reconnect these outputs to the channel modulator. Since these are differential pairs,
it is recommended to use two pair shielded audio cables rather than the single wire and
shield type. For best quality audio, please take care to ground the shield on both the IRD
GND terminal and at the channel modulator end.
• For services transmitted in stereo and used in your plant as stereo, connect the Left
Audio Out terminals (L+ and L-) to the left audio inputs on the channel modulator, and
connect the Right Audio Out terminals (R+ and R-) to the right audio inputs on the
channel modulator.
