Installation
Before setting up the Digital Signage broadcast system, make sure
there is a plan for the Cat5 cable deployment. The cabling layout
should be based on providing the shortest cable lengths, while
avoiding sources of electromagnetic interference. The cabling between
the transmitter unit and receivers should also not pass through any
standard networking equipment (e.g. routers, switches, etc) as they do
not communicate with each other using standard networking protocols.
DS128 Transmitter Installation
Make sure the VGA video source and all remote display devices are1.
powered off.
Place the DS128 broadcaster near the VGA video source and plug2.
in the power adapter.
Connect an RJ45 Ethernet cable from the Broadcaster Unit’s LAN3.
port to a network access point (e.g. network router, switch, hub, etc.).
The “Ethernet” port acts as a network hub, if the video source also
requires a network connection.
Connect the VGA video source to the input connector on the4.
Broadcaster using a standard male/female VGA cable. If using audio
as well, connect a 3.5mm mini-jack cable from the audio source to
the audio input connector on the Broadcaster.
OPTIONAL: Connect a DB9 serial cable from the serial control unit
(e.g. computer system) to the DB9 serial input on the Transmitter with
the appropriate type of serial cable for your setup.
OPTIONAL: Connect a local monitor and/or speakers to the “Monitor”
VGA and 3.5mm mini-jack connector on the Broadcaster.
Connect an RJ45 terminated Category 5e UTP cable to the output5.
connectors on the Broadcaster for each remote display device. This
cable must be a straight run from the Broadcaster to the remote
location, without passing through any networking equipment (e.g.
router, switch, hub, etc.).

DSRXL Receiver Installation
Place the DSRXL Receiver unit near the remote video display device1.
and connect the power adapter to the Receiver unit.
Connect the Receiver unit’s “Monitor 1” VGA connector to the video2.
display device with a standard male/male VGA cable. If using audio,
connect the audio receiver/speakers to the “Audio” connector for
“Monitor 1”, using a 3.5mm mini-jack cable.
OPTIONAL: Connect the serial controlled device (i.e. the display
device) to the RS232 DB9 connector for “Monitor 1”.
NOTE: A second set of devices can be connected to a single Receiver
unit, by connecting them to the “Monitor 2” connectors.
Connect the UTP cable from the Transmitter unit to the “System In”3.
connector on the Receiver Unit.
NOTE: Receiver Units can be daisy-chained together by connecting
a UTP cable from the “System Out” connector to the “System In”
connector on another Receiver Unit. Up to 5 levels of Receiver Units
can be chained together.
Repeat previous steps for each Receiver unit that needs to be set4.
up.
Once all receiver units are setup, power on the devices connected to5.
the Receiver units and then power up the devices connected to the
Transmitter unit.
Driver Installation
This Extender is a complete hardware solution, so is normally invisible
to any other devices. No driver installation is required for use.
