The GefenToolBox Daisy Chain HD System
New technology using Video Over IP techniques allows the Daisy Chain HD system to
connect up to 100 displays using CAT-5 cables in a daisy chain mode going from one
display to the next. The system utilizes three modules: The Sender, which connects to
the HD source, the Splitter module, which connects to the Sender unit using a CAT5 cable
and the Receiver, which connects to the display. The Splitter unit also has an HDMI output
connector. The Sender, Receiver, and Splitter simplify extension of HDMI and control
signals to create an elaborate network of displays with the ability to route IR control back
from each display location to the source. RS-232 commands can also be distributed over
this daisy-chained network to execute commands such as turning all displays on
or off. Each CAT-5e cable between the source, splitter, and receiver units can be up to
330 (100 meters). Up to 100 Hi-Def displays at resolutions up to 1080p Full HD and
1920 x 1200 (WUXGA) are supported. A low-latency of less than a frame assures that all
displays reproduce audio and video in perfect sync. This easy-to-install and easy-to-expand
system is a great t for Digital Signage applications and also for commercial, entertainment
solutions (such as in bars, restaurants, and stores) that play back the same content using
multiple screens.
How It Works
Connect a computer or other Hi-Def source to the Sender unit’s HDMI input. If IR control
of the source device is required, connect an IR emitter to the Sender unit’s IR Out port and
attach it to the IR sensor window of the source. Connect a CAT-5e cable from the Sender
unit to the Splitter or Receiver unit. Connect an HDTV display to the HDMI output of the
Splitter or Receiver unit. If IR is used, connect a Gefen IR Extender module to the IR
Ext port on the Receiver or Splitter units and place it in a location that has a line-of-sight
access from the display location. To control the source, simply point the IR remote to the
IR Extender module. If using the Splitter unit, and the HDMI needs to be routed to more
displays, connect up to two CAT-5e cables from the Splitter unit to additional Splitters or
Receiver units for branching out.

INTRODUCTION
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE DAISY CHAIN HD SYSTEM
• CAT-5e or CAT-6 cables should not exceed 330 feet (100 meters).
• Shielded (STP) CAT-5 or CAT-6 is recommended. However, unshielded (UTP)
CAT-5 or CAT-6 is acceptable, depending on cable quality, but is not the top choice.
Care should always be given to keep these cables away from power lines and other
electromagnetic interference sources.
• If RS-232-control of the displays from the source side is needed, connect a computer
to the Sender unit’s RS-232 port, and connect the RS-232 ports of each Splitter or
Receiver unit to the displays.
NOTE: Shielded cable has an advantage by providing immunity
to Electromagnetic Interference (EMI) from cell phones and A/C
motors.
