Unpacking And Mounting; Connecting A Unit For L-Band Input - Motorola DSR4410 Operator's Manual

Unpacking And Mounting

The shipping carton contains the DSR4410, two quick disconnect terminals, 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 1U spacing, above and below, for airflow.
Mounting with an air gap between receivers or alternating receivers with low power
consumption equipment that does not block the front to back air flow of the receiver
chassis is suggested.

Connecting A Unit for L-Band Input

To Connect a Unit for a New DigiCipher
First determine which satellite, transponder, Virtual Channel Table (VCT) number, virtual
channel, and audio mode (stereo, 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 Port 0 or Port 1.
• For installations using both polarities of a satellite, connect one LNB coax to each port.
The polarity is programmable for the DSR4410. The default polarity for Port 0 is
Vertical and Port 1 is Horizontal. It is important to record which polarities and ports are
connected to the LNB for later use when inputting information in the front panel
menus. Labeling the coax at the rear panel is also a good practice.
To view video and On-Screen Diagnostics during installation, connect the OSD Video
Output on the unit to a 75 ohm video monitor. After the unit is authorized and outputting
the desired service, reconnect the Video Output to the 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.
