Introduction
The XTENDEX®4K 10.2Gbps DisplayPort USB KVM Extender via CAT6/7 or Fiber provides remote KVM (USB
keyboard, USB mouse and 3840x2160@30Hz UHD DisplayPort monitor) access to a USB computer up to 328 feet
(100 meters) away via CAT6/6a/7 cable, 6.21 miles (10 km) via simplex LC single-mode fiber optic cable, or 1640 feet
(500 m) via simplex LC multimode (OM2 and above) fiber optic cable.
Each KVM extender consists of a local unit that connects to a computer, and a remote unit that connects to an
DisplayPort monitor, bi-directional 3.5mm stereo audio speakers and microphone, RS232, and up to four USB devices
(keyboard, mouse, flash drive, HDD, or touchscreen display).

Supports Ultra-HD 4Kx2K resolutions to 3840x2160 @30Hz YUV 4:4:4, HDTV resolutions to 1080p, and up to
1920x1200.
Signal transmission via one CAT6/6a/7 cable or one single-strand single-mode/multimode LC fiber optic cable.
oUsing CAT6/6a/7 cable:
Extend a 4Kx2K signal up to 328 feet (100 meters).
Extend a 1080p or 1920x1200 signal up to 492 feet (150 meters).
Use with a Gigabit switch to extend a total distance of 656 feet (200 meters) between the
transmitter and receiver – the transmitter and receiver can each be extended 328 feet (100
meters) from the switch.
oUsing single-mode 9-micron cable, extend to 6.21 miles (10 km).
oUsing multimode 50-micron cable (OM2 and above), extend to 1640 feet (500 meters).
DisplayPort features supported:
oDP 1.2
o36-bit Deep Color
oRGB, YCbCr 4:4:4, YCbCr 4:2:2
oDolby, DTS, Stereo, and LPCM
oBandwidth up to 340 MHz (10.2Gbps)
HDCP compliant.
Four USB 2.0 ports for keyboard, mouse, flash drive, HDD or touchscreen display.
oKeyboard and mouse are hot-pluggable.
Supports Plug-and-Play specification.
Using an unmanaged Gigabit network switch, extend up to 32 pairs in Point-to-Point connections.
oUse the DIP switch on the transmitter and receiver to specify the unique identifier for the unit.
Transmitter and receiver units with the same unique identifier will connect to each other. (Only
Point-to-Point connections are supported.)
Supports full-duplex RS232 up to 115200 baud.
EDID pass-through for the support of any DisplayPort display device.
Mounting brackets included for easy surface/wall mounting.

System Installation
1. Attach a display, keyboard/mouse, microphone and speaker, as required, to the DP-Out, USB, MIC-IN and Line-Out
ports of the Receiver respectively.
2. Use a DisplayPort-to-DisplayPort cable to attach the computer DisplayPort output to the DP-IN of the Transmitter.
3. Use a USB-B male to USB-A male cable to connect Transmitter USB-B to the computer USB-A port.
4. Connect the Transmitter’s Line-In/Line-Out to the computer Line-Out/Line-In using audio cables.
5. 5.1 For CATx cable installation: Use a CAT6/6a/7 UTP cable (straight EIA 568B, max. 150 meters depending on
cable quality) to directly connect the Tx to the Rx as a paired connection, or 100 meters (each) to a Gigabit
Ethernet Switch.
5.2 For Fiber cable installation: Connect fiber cable (either Single-Mode (up to 10km) or Multi-Mode (up to 500m)
to the pre-attached 1.25G SFP module of the Tx/Rx SFP Fiber Slot for direct Tx/Rx connection, or connect to a
Gigabit Ethernet Switch.
6. Adjust the Tx/Rx 5-bit DIP Switch to match as a paired connection.
7. Power ON both the Receiver and the Transmitter.
8. The EDID of Rx screen will be detected by the computer Graphic card. The computer DisplayPort/Audio outputs will
be displayed/heard on the Receiver’s monitor and speakers. The EDID info should be available on the computer
graphic control panel.
9. The USB keyboard/mouse at the Receiver will now control the computer at the Transmitter.
When multiple Transmitters and Receivers are connected to a network switch, each pair must have a separate unique
identifier number, determined by the position of the dipswitches on the front of the Transmitter and Receiver. A
Transmitter and Receiver can only connect to each other (pair) if their unique identifier numbers are the same, and
they must not be the same as any other unique identifier numbers on other Transmitters and Receivers connected to
the network switch. That is, each pair of Transmitter and Receiver must have a unique identifier number that match
each other.
If multiple Transmitters have the same unique identifier, the Receiver with the unique identifier will show no video. If
multiple Receivers have the same unique identifier, the Transmitter will send no video to any of those Receivers so
they will show no video.
