INTRODUCTION
The XTENDEX®4K HDMI USB KVM Over IP Extender provides remote KVM (USB
keyboard, USB mouse, and 4Kx2K HDMI monitor) access to a USB computer up to
492 feet (150 meters) over a Gigabit network using a single CAT6/6a/7 cable. The
extender consists of the ST-IPUSB4K-L-VW local unit (Transmitter) that connects to a
computer and the ST-IPUSB4K-R-VW remote unit (Receiver) that connects to an HDMI
monitor, 3.5mm stereo audio speakers and microphone, and up to four USB devices
(keyboard, mouse, flashdrive, HDD, or touchscreen display).
The transmitter and receiver units can be connected together for a Point-to-Point
connection via CAT6/6a/7 cable or a Point-to-Many connection via a Gigabit network
switch. Support for multiple transmitters requires a managed Gigabit network switch.
Supports Ultra-HD 4Kx2K resolutions to 3840x2160 (30Hz), 2K resolution
2048x1080, HDTV resolutions to 1080p, and computer resolutions to 1920x1200.
oExtend 4Kx2K up to 492 feet in a Point-to-Point connection.
oExtend 4Kx2K up to 984 feet in a Point-to-Point or Point-to-Many connection via a
Gigabit network switch.
oThe max length between the switch and the transmitter/receiver unit is 492 feet.
HDMI features supported:
oHDMI 1.4
ox.v.Color, sYCC601 color, Adobe RGB Color and Adobe YCC601 color
oDolby TrueHD, LPCM 7.1, DTS-HD Master Audio, Dolby Digital, and DTS
oBandwidth up to 340 MHz (10.2 Gbps)
oLip Sync
HDCP 1.4 compliant.
Supports USB 2.0 devices.
oKeyboard and mouse are hot-pluggable.
oConnect a mouse, keyboard, flashdrive, HDD or touchscreen display.
Supports video wall installations from 1x2 to 8x16 screens.
oDisplays can be rotated 180 and 270°.
Plug-and-Play installation allows receivers to find the transmitter automatically on the
same network. (Network configuration may be required for managed network
switch.)
Full Infrared Remote (IR) control of HDMI source from remote HDTV using existing
source remote control.
Support for multiple transmitters requires a managed Gigabit network switch with
VLAN/IGMP support. Standard LAN switches can only support one transmitter.
Each VLAN acts as a separate HDMI Over IP Channel on the network.
When using multiple remote units, only one unit can have USB control over the
source at any time.
Manage transmitter/receiver connections and video wall configuration with built-in
software.
Supports full-duplex RS232 up to 115200 baud.
Customizable EDID table on local unit.
Supports the DDC2B protocol.
