Routine Operation 2-5 DRS4000 Receiver User and Technical Manual
ASI OUT Connectors The two ASI OUT connectors are 75
ohm, female, BNC connectors that provide ASI outputs for digital
video and audio distribution.
ASI IN Connector The ASI IN , 75 ohm, female, BNC connector
accepts an ASI signal input from another component. It is used
for local decoding of a SD/HD ASI stream when the receiver is
placed in external ASI mode.
70 MHz IN Connector This connector is a 75 ohm, female,
BNC connector that accepts input from another receiver. This is
an alternative input to
BDC 1 and is selectable from the Control
screen menu.
AUDIO Connectors These mini-XLR connectors provide
analog audio 1 outputs and switch between analog audio 2 or
AES outputs.
RS-232 CNTRL Connector This connector is an RS-232, DB-9,
male connector that can be used to remotely control the
DRS4000 Receiver via a slave controller.
POWER connector The POWER connector accepts a standard
3-prong cable for AC power. An auto-sense circuit accepts
either 110 to 130 VAC or 205 to 260 VAC @ 2 amps. The 3-
prong male end must be modified for non-U.S. applications.
2.2.3 PACKET Connectors
The following connectors provide inputs and outputs for the
optional packet switching subsystem.
ASI IN 1 thru ASI IN 4 Connectors The 75 ohm, female, BNC
connectors allow up to four ASI inputs from different receive
sites, effectively acting as a diversity switch. They can also be
used as an ASI multiplexer. The maximum bit rate is adjustable
up to 40 Mbps.
ASI OUT Connectors The two ASI OUT connectors are 75
ohm, female, BNC connectors that provide a diversity ASI output
or a multiplexed ASI output according to the mode set for the
packet.
SDI OUT Connector This connector is a 75 ohm, female, BNC
connector that provides aa SD only digital video stream output.
2.3 Preparing for Operation
The procedures required to operate the DRS4000 receiver are
contained in the following paragraphs. The color LCD Control
menu and the keypad are used to control all features of the
receiver.
2.3.1 Installation
The DRS4000 receiver is typically mounted on a 19-inch (48.3
cm) rack. The unit and cabling are permanently installed and
power comes from facility power.
For additional information, refer to the “Installation” Chapter on
page 4-1 .
The following paragraphs provide steps to power up and power
down the receiver. If the receiver is installed at an unattended
central receive site, then it typically stays powered up for
extended periods of time.
When the power switch is set to on ( I ), the video monitor will
initially display a blank screen and the Control menu will display
color bars, a logo screen, and finally the Control menu. The
settings displayed when the Control menu is displayed will be the
settings in effect when the unit was last powered down.
2.3.2 Powering the Receiver
The following paragraphs provide steps to power up and power
down the receiver. If the receiver is installed at an unattended
