Extend and Distribute DVI, USB, RS-232, IR, and 2-way audio over a Local Area Network using any combination of HDMI, DVI, and VGA Senders and Receivers

The DVI KVM over IP extends DVI, USB, 2-way analog audio, RS-232, and IR, over a Gigabit Local Area Network. Resolutions up to 1080p Full HD and 1920 x 1200 (WUXGA) are supported. The Gefen Video over IP products can be used as a "Virtual Matrix". When using HDCP-encrypted content, only HDMI Senders and Receiver units can accept and display the content. HDMI digital audio is also supported when using HDMI sources and displays with HDMI-to-DVI adapters. The Sender and Receiver units can be automatically or manually configured to unique IP addresses to allow the connection of multiple Senders and Receivers to the same network. Multiple Receiver units can simultaneously connect to any Sender unit within the network to create a virtual crosspoint matrix of 256 Senders and up to a theoretical limit of just over 65,000 units total, depending on the network bandwidth and number of ports on the network switch. Each Receiver unit has a built-in Ethernet switch and two additional RJ-45 Ethernet ports to allow for the connection of computers and other IP-enabled devices. USB 2.0 data rates up to 480 Mbps are supported in addition to backward-compatibility with USB 1.1. Each Receiver unit provides two USB ports with up to 500mA current draw per connector, providing access to keyboard, mouse, and other compatible devices. Bi-directional analog audio capability allows audio to be transported between the Sender and the Receiver units. The built-in mic pre-amp on the Receiver unit ensures compatibility with a variety of microphones. IR commands from the Receiver side can be extended to sources connected to any of the Senders units. RS-232 serial control can also be extended between each Sender and Receiver unit. The built-in Web server interface makes set-up and configuration simple and intuitive. The DVI KVM over IP is perfect for large scale remote workstation access and digital signage applications.

The HD over IP w/ RS-232 and 2-way IR extends HDMI, RS-232, and bi-directional IR over a Gigabit Local Area Network. Resolutions up to 1080p Full HD and 1920 x 1200 (WUXGA), HDCP, Deep Color, 7.1 channel High Bit Rate digital audio, and Lip-Sync pass-through are supported. The Sender and Receiver units can be automatically or manually configured to unique IP addresses to allow the connection of multiple Senders and Receivers to the same network. Multiple Receiver units can simultaneously connect to any Sender unit within the network including the Gefen KVM over LAN products with HDMI, DVI, or VGA video, to create a virtual crosspoint matrix of 256 Senders and a theoretical limit of just over 65,000 units total, depending on the network bandwidth and number of ports on the network switch (see Notes 1 and 2).

Pigtail module HDMI extension using a single-strand multimode fiber optic cable with HDCP support

The HDMI fiber optic pigtail module extender with HDCP support extends HDMI up to 1000 feet (300 meters) using a single-strand 50/125µm multimode (OM2) SC-terminated fiber optic cable. It supports resolutions up to 1080p Full HD and HD lossless audio formats like LCPM 7.1 audio, Dolby® Digital Plus, Dolby® TrueHD, and DTS-HD® Master Audio™. Optical signal transmission provides galvanic isolation and immunity to electromagnetic interference compared to similar copper based extension modules. The pigtail design of the Sender and Receiver modules relieves stress and clutter on the source and display connector panels. Their compact design makes them ideal for fitting neatly behind equipment for a clean installation, making it a great way to easily extend HDMI.

Keep HDMI sources and displays in perfect sync

High Definition displays with HDMI inputs use EDID (Extended Display Identification Data) to ensure that a connected Hi-Def source sends compatible audio and video signals. In some scenarios, this data can be lost, resulting in an incorrect signal or complete loss of audio and/or video. The Gefen HDMI EDID Detective Plus has been designed specifically to address this issue by recording the display EDID date and making it available to the Hi-Def source reliably and on a continuous basis. With DDC re-clocking technology, the reliability of HDCP handshaking is improved, ensuring that the Hi-Def source always receives the correct EDID. Using the Gefen Syner-G PC software or terminal emulation via USB, the installer can also manipulate/modify the EDID data to meet installation-specific requirements and resolve system-specific compatibility issues. The HDMI EDID Detective Plus has been designed for quick and easy programming and installation.

How It Works

To program the EDID, connect the included HDMI cable from the Detective to the HDMI input of the display. Connect the included power supply to the unit and plug the power cord into an available electrical outlet. Disable the Write Protect Switch, set the DIP switches to the appropriate positions, and press the Program button. Once the EDID programming is completed, the display and power supply can be disconnected without losing the recorded EDID. If a suitable EDID cannot be recorded, there are six pre-programmed EDID profiles and six user-programmable EDID banks that can be used. Instructions for selecting one of the pre-programmed EDID profiles and for copying/ uploading additional EDIDs are outlined in the user's manual.

Connect an HDMI cable, up to the recommended maximum cable length, from the Hi-Def source to the HDMI input on the Detective. Re-connect the included DC power supply and plug the power cord into an available electrical outlet. Power on the source and the display and a pristine Ultra High Definition picture will appear.

The EXT-HDMI1.3-142D 1x2 HDMI Splitter allows set-top boxes, DVD players, DVRs and even computers to be connected to two HDTV displays simultaneously. A toslink output on the rear of the splitter feeds digital audio to an external amplifier or receiver for additional installation flexibility. A greater number of HDTV displays can be daisy-chained together to create a larger distribution.
