DVB+™ Satellite Receiver
Installation Guide for Certified Equipment Technicians
DVB+™ is a commercial quality, DVB-S compatible satellite receiver designed to
receive, demodulate, and process data streams on high-speed satellite carriers.
Installation should only be performed by technicians certified to install satellite
receive equipment.
Installers should assemble and align an approved satellite antenna ("dish") and
attach RG-6 cable ("coax") to the appropriate connectors on the dish. To prevent
electrical fire and minimize equipment damage due to lightning, the RF coax cable
shield must be connected to earth ground with #10 or heavier gauge solid copper
wire at the point of entry into the building.
Coax is then attached to the DVB+™ receiver via the F connector labeled "RF INPUT"
on the rear panel. The coax cable provides power to the LNB and carries the
950-2150 MHz RF signal from the LNB to the receiver. The RF input level for the
desired carrier should be between -65 dBm and –25 dBm. An RF in-line amplifier
must be used for cable runs of more than 100 feet.
Depending upon the installation, data is passed from the DVB+™ receiver via an
Ethernet or serial connection. For installations using Ethernet output, installers
connect CAT5 Ethernet cable from the 10/100Base-T port of a suitable switch,
router, or PC to the rear panel RJ-45 Ethernet port labeled "DVB". When
connected properly, the LINK light on the connector will illuminate. Installers
should note that when connecting directly to a PC, an Ethernet crossover cable
must be used.
The other RJ-45 Ethernet connector, labeled "AUX" is for system maintenance and
some low-speed data services. This port should NOT be used for normal operation
unless specified by Mainstream Data.
For installations using the Serial connection alternative, installers connect a
shielded DB-9 data cable from the COM port of a PC to the rear panel RS-232 serial
port. Refer to the pinout diagram on back for detail on connector pinouts. To
prevent unwanted RF radiation from the data cables, only cables with an electrical
shield should be used. The shield wire within the cable should attach to the
connector shell at both ends of the cable.
The external power module attaches to the "POWER IN" connector on the rear
panel of the DVB+™ Satellite Receiver. The power module should be disconnected
from the AC plug during installation and when cables are being changed to prevent
accidental shorts.
After all equipment has been installed properly, installers should power on the
DVB+™ receiver. The top blue LED light will illuminate. DVB+™ automatically
attempts carrier lock based upon stored settings. When carrier lock is achieved,
the second blue LED will illuminate.
If the DVB+™ receiver has not locked to a carrier within a few seconds one of three
situations exists: 1) RF cabling is improperly installed, 2) dish is misalignment, or 3)
receiver is not configured properly. Recheck the installation to ensure proper
connections. If the situation persists, refer to the DVB+™ User Manual or contact
Mainstream Data Customer Support directly.
