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.

CONNECTING THE DAISY CHAIN HD SYSTEM 1. Connect a Hi-Def source to the Sender unit using the included HDMI cable. The Daisy Chain HD System can be connected in two ways: ►► Daisy-Chaining using Splitters • Connect a CAT-5 cable, up to 330 feet (100 meters) from the Link Out jack on the Sender unit directly to the Link In jack on a Splitter unit. • Daisy-chain additional Splitter units, if desired, by connecting a CAT-5 cable (up to 330 feet) between the Out A and Link In jacks on each Splitter unit.
CONNECTING THE DAISY CHAIN HD SYSTEM to Hi-Def source Sender Up to 330 feet (100 Meters) to HDTV Display (or other HDMI device) Receiver 3. Additional displays can be connected to the Splitter units (if used) by connecting an HDMI cable between the HDMI Out port and each HDTV display. 4. Connect an IR Emitter (Gefen part no. EXT-RMT-EXTIRC) to the IR Ext jack on the Receiver unit(s). 5. Connect an IR Extender (Gefen part no. EXT-IREMIT) from the IR Out jack on the Sender unit to the Hi-Def source.
OPERATING THE DAISY CHAIN HD SYSTEM Connection Depth The maximum number of levels of Splitter and/or Receiver units that can be connected within the Daisy Chain HD System is dependent upon how each unit in the system is connected. This number is referred to as the depth. For example, the most elementary system consists of only a single Sender unit and has a depth of 1. If a Splitter (or Receiver) unit is attached to the Sender unit, then the depth becomes 2.
OPERATING THE DAISY CHAIN HD SYSTEM LED Link Indicators The Link LED indicators on the Sender, Splitter, and Receiver unit provide basic information on the current status of the Daisy Chain HD System. Condition 1 2 • Power connected to Sender, Splitter, and/or Receiver • CAT-5 cable connected (or not connected) to Splitter(s) / Receiver(s). • Source is not connected to the Sender unit. • Power connected to Sender, Splitter, and/or Receiver.
OPERATING THE DAISY CHAIN HD SYSTEM EDID Management The default EDID The Sender unit contains a default EDID which supports the following: Color Depths Audio Sampling Rates Resolutions / Timings 640 x 480p @ 72 Hz 720 x 480i @ 60 Hz 720 x 480p @ 60 Hz 720 x 576i @ 50 Hz 720 x 576p @ 50 Hz 16 / 20 / 24 bit 32 / 44 / 48 kHz 1280 x 720p @ 50 Hz 1280 x 720p @ 60 Hz 1440 x 480p @ 60 Hz 1440 x 576p @ 50 Hz 1920 x 1080i @ 50 Hz 1920 x 1080i @ 60 Hz 1920 x 1080p @ 50 Hz 1920 x 1080p @ 60 Hz The default EDID i
OPERATING THE DAISY CHAIN HD SYSTEM EDID Programming Procedure NOTE: Before programming the EDID, a Sender and at least one Receiver must be connected using CAT-5 cable. 1. Make sure that the display (or other A/V device) is connected to the Receiver unit and that all other Receiver / Splitter connections have been made (see pages 10 - 11 ). 2. Select the Receiver that is connected to the display (or other A/V device) that has an EDID that is most compatible with all devices in the system. 3.
OPERATING THE DAISY CHAIN HD SYSTEM EDID has been updated OK If the EDID is identical to the EDID that was just programmed, “EDID the same as host” will be displayed on the screen. How the EDID is applied The programmed EDID will be used by all other displays (or other A/V devices) in the system. For example, in the illustration below, the EDID button was pressed on Receiver “A”.
OPERATING THE DAISY CHAIN HD SYSTEM Controlling the source using IR The Hi-Def source can be controlled from the viewing location by connecting an IR Extender (Gefen part no. EXT-RMT-EXTIRC) to each Receiver unit. Refer to the illustration below.
OPERATING THE DAISY CHAIN HD SYSTEM Determining the current Mode The EDID switch on the Daisy Chain HD System has two functions: 1) Fetch the downstream EDID and store it in the Sender unit. 2) Display the current mode (broadcast or unicast) of the system. 1. Make sure that a display is connected to the Splitter or Receiver unit that is to be queried. 2. Quickly press and release the EDID button on the Splitter or Receiver unit. 3.
OPERATING THE DAISY CHAIN HD SYSTEM Default Settings for the Daisy Chain HD System When the Daisy Chain HD System is unpacked from the box, the unit will be in Broadcast Mode and will be set to a baud rate of 9600. Therefore, if multiple RS-232 devices (e.g. displays, etc) will be controlled at 9600, then placing the Daisy Chain HD System in configuration mode will not be necessary. To change baud rates or switch between broadcast and unicast mode, see the examples below.
OPERATING THE DAISY CHAIN HD SYSTEM 4. Type the following at the boot# prompt: socat5 b 115200 19200 Sets the Sender unit baud rate to 115200. This baud rate can be changed if necessary. socat5 b 115200 19200 Sets the Receiver / Splitter unit(s) baud rate to 19200. This baud rate is required by the GTV-AUDDEC-N. “b” sets the system to broadcast mode. 5. Press the [ENTER] key.

Launch a terminal-emulation program (e.g. HyperTerminal, etc) and configure the serial port using the settings provided on page 25. Make sure that the terminal baud rate is set to 115200. 2.
OPERATING THE DAISY CHAIN HD SYSTEM Before setting unicast mode, it is important to identify the RS-232 device in the system with which the computer will be communicating. We will use the same setup as before. However, this time we wish to talk to the RS-232 device connected to the Receiver unit (highlighted in yellow). to Hi-Def source Sender Display EC-N AUDD GTV- Splitter RS-232 device (GTV-AUDDEC-N) Receiver RS-232 controller (Computer) Display EC-N AUDD GTV- 5.
OPERATING THE DAISY CHAIN HD SYSTEM Sets the Sender unit baud rate to 115200. This baud rate can be changed if necessary. socat5 u 115200 19200 4 0 3 “u” sets the system to unicast mode. Selects the Splitter or Receiver in the system that we want to talk to. Sets the Receiver / Splitter unit(s) baud rate to 19200. This baud rate is required by the GTV-AUDDEC-N. One distinct difference in typing the command line for unicast mode, is that the ID and depth of the unit must be specified.
OPERATING THE DAISY CHAIN HD SYSTEM V008.01 ID: 4 0 DEPTH: 3 HD Audio socat5: Unicast Is Me H: 115200 C: 19200 The diagram below illustrates how RS-232 commands (black arrows) from the computer (RS-232 controller) is distributed to the device that was specified as part of the command line in Step 6. The depth of each unit in the system is indicated by the numbers in red. Note that the computer can only communicate with the RS-232 device that is connected to the Receiver unit (depth = 3).

NETWORK CABLE WIRING DIAGRAM Gefen recommends the TIA/EIA-568-B wiring option. Please adhere to the table below when field terminating cable for use with Gefen products. Pin Color 1 Orange / White 2 Orange 3 Green / White 4 Blue 5 Blue / White 6 Green 7 Brown / White 8 Brown 12345678 CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types. Gefen recommends using solid core cabling. CAT-6a cable is also recommended.
SURFACE MOUNTING INSTRUCTIONS The GefenToolbox Daisy Chain HD System should be mounted vertically on a wall or inside / outside a cabinet with wood / drywall screws as shown in the diagram above. There should be an inch or two of clearance between the edges of the unit and any walls or vertical surfaces to allow for enough clearance for connection and disconnection of the HDMI cable. For installation on a drywall surface, use a #6 drywall screw.
