INTRODUCTION

The XTENDEX® 4K(30Hz) HDMI USB KVM Extender over IP via Fiber provides remote KVM (USB keyboard, USB mouse
(USB1.x/USB2) and 4Kx2K UHD HDMI monitor) access to a USB computer up to 9,842 feet (3,000 meters) away via a duplex LC
singlemode fiber optic cable and 1,804 feet (550 meters) using duplex LC multimode fiber optic cable.

Each KVM extender consists of a local unit that connects to a computer and also supplies video to a local monitor, and a remote
unit that connects to an HDMI monitor, 3.5mm stereo audio speakers and microphone, RS232, and up to four USB devices
(keyboard, mouse, flash drive, HDD, or touchscreen display). The local and remote units can be connected together for a Point-to­Point connection via fiber cable, or a Point-to-Many or Many-to-Many connection via a managed Gigabit network switch.

Features:

 Signal transmission via two-strand singlemode LC fiber optic cable.

o Using singlemode 9-micron cable, extend to 9,842 feet (3,000 meters).
o Using multimode 50-micron cable, extend to 1,804 feet (550 meters).

 Supports Ultra-HD 4Kx2K resolutions to 3840x2160 (30Hz), 2K resolution 2048x1080, HDTV resolutions to 1080p, and up

to 1920x1200 (WUXGA).

 HDMI features supported:

o HDMI 1.4
o x.v.Color, sYCC601 color, Adobe RGB Color and Adobe YCC601 color
o Dolby TrueHD, LPCM 7.1, DTS-HD Master Audio, Dolby Digital, and DTS
o Bandwidth up to 340 MHz (10.2 Gbps)
o Lip Sync
o HDCP 1.4 compliant.

 USB ports for keyboard, mouse, flash drive, HDD or touchscreen display.

o Keyboard and mouse are hot-pluggable.

 Supports video wall installations from 1x2 to 8x16 screens.

o Displays 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.)

 Support for Point-to-Many or Many-to-Many connections requires a managed Gigabit network switch with IGMP support

and Jumbo frame support.

o Manage transmitter/receiver connections and video wall configuration with web interface or network switch that

supports VLAN; Each VLAN group acts as a separate HDMI Over IP Channel on the network.

 When using multiple remote units, there are two USB control modes - Exclusive Mode and Sharing Mo de.

o USB Exclusive Mode: Only one remote unit can have USB control over the source computer at any time.
o USB Sharing Mode: Multiple remote units share the control of the source computer.

 Up to 5 USB devices will be recognized by the computer.
 Full Infrared Remote (IR) control of HDMI source from remote HDTV using existing source remote control.
 Supports full-duplex RS232 up to 115200 baud.
 Customizable EDID table on local unit.
 Supp
 Easily expandable – add receivers as you add control stations.
 Integrated mounting brackets for easy surface/wall mounting.







Enable USB over IP ---> Check to enable TX’s USB over IP feature (default Enabled). It works as a 5-port Virtual HUB when TX
is attached to a USB port on the PC. Up to 5 Virtual USB ports will be sequentially linked to the connected RX USB devices.
There are 4 USB ports on each RX, but only the ports with devices attached (up to 5 total) will occupy the TX’s Virtual USB port.



Operation Mode --->The TX USB-over-IP supports the following 2 operation modes:

Exclusive Mode: All of TX’s 5 Virtual USB ports will be exclusively assigned to the RX which has the USB access right.

The other RXs can request USB access right manually.
Sharing Mode: The TX’s 5 Virtual USB ports can be shared by multiple RXs. Depending on the number of USB
devices on each RX, it is possible to have maximum 5 RXs sharing the same TX’s Virtual USB. If more
than 5 devices are connected, the TX will randomly select the 5 ports that will work. The remaining
devices will be ignored.

Note: In Sharing Mode, using more than one mouse or keyboard at the same time from two different RXs will have
undesirable results, as the PC will try to respond to both.

Compatibility Mode

Mouse not responding well ---> enable this setting when mouse is slow and not very responsive.
K/M over IP ---> The TX also has built in K/M over IP HID emulation for multiple RXs to share the same TX’s

keyboard/mouse. This feature will occupy one TX’s Virtual USB port when it is enabled (default: Enabled).

13

USB over IP KMoIP ports (RX)
There are 2 x USB 1.1 and 2 x USB 2.0 ports on each RX. These 4 USB ports can be configured for USB-over-IP or KM-over-IP
devices. The USB-over-IP devices will be virtually linked to the TX’s 5 VirtualUSB ports; the KM-over-IP devices will be linked and
shared with the TX’s K/M over IP HID emulation port.
The advantage of USB-over-IP device have better USB compatibility, for example USB Touch, Disk, … devices must be configured
with USB-over-IP. The advantage of KM-over-IP device is to have multiple RXs sharing the same TX’sK/M over IP HID emulation
port. It is recommended to configure the 2 x USB 1.1 (keyboard/mouse) as KMoIP ports and 2 x USB 2.0 as USB over IP ports (for
Touch, Disk).

Type 1 guest: similar to type 1 but using PC to link with RX’s RS-232.
Type 2 guest: similar to type 2 but using PC to link with RX’s RS-232.
Baudrate Setting for Type 2

Point-to-Many connection via RS232

If one local unit pairs with multiple remote units, then point-to-many RS232 is supported.

When the Tx unit sends RS232 message, all Rx units receive the same message.
When multiple Rx units send an RS232 message at the same time, the fastest Rx will take control. The Tx unit

will only receive that Rx's message and reject messages sent from other Rx units. Once the controlling Rx stops
sending messages for about 1~2 seconds, the control authority will be released and all Rx units will be competing for
priority again.

16

Audio Output (RX)
If the TX’s input audio is in HDMI, you can route the audio output on Line Out of the RX:

INSTALLATION(TX/RX)

1. The factory default Connection Method for RX is “First Available”, and TX is in Multicast mode with its default
Multicast IP (shown on the label). It means all TXs will send packets with default Multicast IP (225.0.10x.xxx), and
all RXs will find the first available TX for connection.

2. Use an Optical Fiber cable to directly connect TX/RX as a pair connection, or connect to an IGMP-enabl ed
Gigabit Ethernet switch for many-to-many installation.

Note: Each TX comes with individual factory default Multicast IP which is shown on the unit label.

3. Connect TX/RX to a video source/screen using an HDMI cable.

4. The TX factory default EDID setting is 1920x1080 @60Hz.

You can change TX to “Copy EDID from EDID Master“, and perform step 4.1/4.2 to assign a RX as the EDID
Master.
You can change TX to “Copy EDID from the 1
steps 4.3 or 4.4.
Or you can change and use the TX built-in EDID as instructed in step 4.5:

4.1 Press and hold the Mode button of the specific RX unit and power ON until Green LED blinking then
releasing the Mode button, this RX will be assigned as EDID Master (RX’s Green LED will blink, then steady
ON, and Amber LED Off to indicate it is ready and waiting for connecting with TX). Then power ON other RX
units sequentially.

4.2 Refer page 9, enable “Copy EDID from this Video Output” to assign a specific RX as EDID Master.

4.3 Refer page 6, enable “Copy EDID from 1

4.4 Refer page 6,enable “Copy EDID from RX IP” to set TX EDID from a specific RX.

4.5 To use TX built-in EDID for specific Resolution, refer to page 7 “Resolution Selection”.

5. The following start-up messages will be displayed during RX power on:

FW: 02-Jan-2019 A6.6.0.8 (Firmware date and version)
Local IP: 10.0.34.38 (RX’s IP address)
MAC: 0020FExxxxxx (RX’s MAC address)

Connection Method: First Available

Remote IP: 10.0.x.x/ 225.0.x.x (Connecting target TX IP / Multicast IP)

6. To get the best video performance, please refer to page 10 to enable TX/RX Jumbo Frame setting, and set
Ethernet Switch Jumbo Frame with minimum 8K bytes.
