In this mode, the Receiver unit is always powered. DIP Switch 2 - RS-232 Mode (Default = OFF) • OFF - Pass-through Mode Pass-through mode for RS-232. This is default position. • ON - Firmware Upgrade Mode Firmware Upgrade mode (See page 13 for instructions). If DIP switch 2 is in the ON position, RS-232 cannot be extended. 9 DIP SWITCH CONFIGURATION Receiver Unit The Gefen DVIKVM Extra Long Range Extender contains four (4) DIP switches on the bottom of the Receiver Unit. Each DIP switch performs a different function. DIP Switch 1 - EDID Mode (Default = OFF) • ON - Pass-Through Mode DDC and HPD are passed through. Both the connection status and the full video capabilities of the monitor are used by the source device. • OFF- Local EDID Mode Local EDID is used instead of the EDID from the display device. EDID features newer than HDMI 1.3 are removed when the display is read. This provides a general EDID which is compatible with more displays. 10 DIP SWITCH CONFIGURATION DIP Switch 2 - Hot Plug Detect (Default = OFF)* • ON- HPD Pass-Through HPD follows upstream HPD towards the source. The HPD signal will reflect the connection status between the display device and the source device. If the source or monitor is temporarily disconnected then reconnected, there will be a delay of 20 - 30 seconds before the content is restored to the monitor. • OFF- HPD Always High The HPD signal remains high regardless of the downstream HPD state. If the source or monitor does not properly handle HPD (no picture after connecting / reconnecting source or display), set this DIP switch to the OFF position. DIP Switch 3 - Supports DVI Connections (Default = ON)* • ON- Disable HDCP If a DVI connection is used, set DIP 3 to the ON position. DVI is supported by disabling HDCP pass-through. • OFF- Enable HDCP If an HDMI device is connected, set DIP 3 in the OFF position. ‘DIP switch is only operational when using Local EDID (DIP 1 = OFF). 11 DIP SWITCH CONFIGURATION IMPORTANT: The Green Mode feature on the Receiver unit is ■ not implemented on hardware versions prior to 9502. Check the hardware version, printed on the bottom of the Receiver unit. For example, the sample image below Indicates hardware version 9401 which does not have the Green Mode feature.

Automatic Power Mode consumes less than 1 Watt of power. • ON - Disable Green Mode If DIP switch 1 is set to the ON position, then the Receiver unit is placed in Power Always Mode. In this mode, the Receiver unit is always powered. 12 912108 FIRMWARE UPDATE Updating the Firmware @STOP: Before beginning the update process, disconnect the Sender unit from the Receiver unit. 1. Connect an RS-232 cable from the computer to the Sender Unit. 2. Set DIP switch 2 on the Sender unit to the ON position. 3. Connect the 5V DC locking power supply to the Sender Unit. 4. Go to the directory where the firmware files are stored. 5. Double-click the .BAT file. A screen similar to the following will appear: Found sink on port 4 Autodetect platform: full sink Autodetect platform: spi.

To update the firmware on the Receiver unit, set ALL DIP switches on the Receiver unit to the ON position. 8. Connect the 5V DC locking power supply to the Receiver unit. 9. Repeat steps 4 and 5. 10. The firmware update process is complete. 13 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 m m —III! 1 2345678 CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types. Gefen recommends using solid core cabling. It is recommended to use one continuous run from one end to the other. In some cases, connecting through a patch might not work. 14 WALL MOUNTING INSTRUCTIONS The GefenToolBox DVIKVM ELR Sender and Receiver may be mounted vertically in a wall or 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 insertion and retraction of cables at the DVI and RS-232 connectors. For installation on a drywall surface, use a #6 drywall screw. It is recommended when installing on a drywall surface that studs be used to secure...
