Introduction to CSR820
The CSR820 is a commercial Integrated
Receiver/Decoder (IRD) intended for use in
cable head-ends and other digital satellite
downlink applications. It may be placed on a
desktop or installed into a standard 19-inch
equipment rack.
The CSR820 accepts L-Band input from an LNB.
The CSR820 demodulates, decrypts, and
decompresses the digital signal and converts it
into composite video, analog audio, and RS-232
data outputs.
Features
• Accepts QPSK modulated 950–2150 MHz L-
Band input at symbol rates of 1–45 Msps.
• Front panel control with alphanumeric
display and LED fault indicators.
• Processes MPEG-2, Main level, Main profile
compliant signal.
• DVB compliant.
• NDS VideoGuard™ Conditional Access, with
ISO 7816 Smart Card.
• NTSC or PAL B, D, G, H, I, M, N, video
formats.
• Provides one composite video and one
stereo or two mono audio channels.
• Accepts flash download over network.
• Voltage range from 100-240 VAC. Provides
selectable DC voltage to the LNB.
• Alarm relay contacts to control external
equipment.
• Reinsertion of closed captioning. Provides
DVB teletext and embedded subtitling.
• Outputs 19.2 Kbps Asynchronous serial data
through an RS-232 port.
• Network Control Protocol, over-the-air
command capable.
• Ad insertion relays controlled by over-the-air
command.
• High performance video and audio
(professional quality).
• LNB polarity control through LNB voltage
change.
Safety Notes
Observe the safety cautions on the label affixed
to the bottom of the CSR820. Also observe
general industry safety practices while working
with the CSR820.
1. The CSR820 must be properly grounded to
aid in current surge protection.
2. The CSR820 must have Power OFF before
making cable connections.
3. The ambient temperature of the CSR820
must not exceed 122° F (50°C).
4. For desktop use, ensure that four rubber feet
are firmly installed on the bottom of the
CSR820. Do not stack more than three units
on top of each other.
5. For rack mounting, leave a minimum of one
rack unit space above and below each unit for
ventilation.
6. Do not use liquids near the CSR820.
7. Do not block the ventilation openings.
8. If multiple CSR820s are connected to an
LNB, ensure that only one CSR820 LNB
voltage is turned on. Turn off the LNB
voltage on the other IRDs. (see pages 8 and
10 - “LNB Voltage”).

Installing the CSR820
Product Contents
Your CSR820 is shipped with the following
items:
2 Rack mounting brackets
2 Plug-in connector blocks (9-pin)
1 US Power cable
1 Installation and Operation Guide
The CSR820 may be installed into a standard
ANSI/EIA RS310-C 19” (48mm) rack (one rack
unit height). Installation includes attaching signal
connections and powering-up the unit.
Figure 2: Rack Mounting
1. Locate the two mounting brackets in the
installation kit.
2. Use the existing mounting screws on the
CSR820 to install the mounting brackets
onto the sides of the IRD.
3. Place the unit in the rack. Mount the
CSR820 to the rack using four screws (not
supplied).
4. If the mounting brackets are attached
properly, they will support the weight of the
CSR820. Leave one RU space above and
below each unit for reliable operation.
