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 PC USB. These 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 port with device attached 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.
Compatibility Mode
Mouse not responding well ---> enable this setting when mouse is slow and queer.
K/M over IP---> The TX also 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).
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 5VirtualUSB 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’s K/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).
The RX USB over IP Configuration Web page:

This USB over IP setting must be enabled for any USB devices to be attached with TX’s Virtual USB HUB.

13
The RX Main KMoIP ports Configuration Web page:

Enable the port #1, 2, 3, 4 for the device to be linked with the TX’s K/M over IP HID emulation port. Default is
Port 1 and 2 KMoIP Enabled.
Note: All of RX’s 4 x USB ports will be auto configured as KMoIP if the USB over IP is disabled.
Hotkey (RX Main only)
The dual head RX supports Hotkey for OSD Menu. To choose the RX OSD Hotkey:
Functions --->Hotkey ---> select the Hotkey from the list: <Ctrl><Ctrl>, <Shift><Shift>, <Alt><Alt>, or
<Scroll><Scroll> (default: Ctrl Ctrl).


Audio Output (RX)
If the TX’s input audio is in HDMI, you can route the audio output to the Line Out of the RX:
Functions --->Audio Output ---> check “HDMI Audio De-Embedder”.
Click Apply to save the setting and reboot. (default is Disabled)
The DVI Out on the RX will not pass audio through to an HDMI monitor's speakers if one is connected. You must
use the "Line Out" port with self-powered speakers to hear audio from an HDMI audio input.
When this feature is disabled, Local Audio Input and Remote Audio Output always work together. Remote Input and
Local Output only works when extender units are in Unicast (one Tx pairs with only one Rx) mode.

14
Multi-Screen Setting (TX Main only)
The system supports Multi-Screen feature which is useful for PC with multiple HDMI screen outputs (above):
Main Video: Enable this setting if this TX is connected to the PC’s main video output.
Note: Any TX with Main Video setting disabled will not be shown on the OSD Transmitter List.
2nd Video TX IP: Type in another TX IP address which is connected to the PC’s 2nd video output. (This 2nd TX IP
will be set when the dual head TX is powered ON.)
3rd Video TX IP: Type in another TX IP address which is connected to the PC’s 3rd video output.
4th Video TX IP: Type in another TX IP address which is connected to the PC’s 4th video output.
Multi-Screen Setting (RX Main only)
As above in the RX Main Multi-Screen Setting Web page:
2ndScreen RX IP: Type in another RX IP address which is connected to the 2nd screen. (This 2nd RX IP will be set
when the dual head RX is powered ON.)
3rd Screen RX IP: Type in another RX IP address which is connected to the 3rd screen.
4th Screen RX IP: Type in another RX IP address which is connected to the 4th screen.
When the Main RX switches to a new TX, its associated RXs will also be switched to the new TX’s associated
TXs automatically.
Mirror (RX only)
When the “Mirror” option is enabled, the associated RXs will connect to the same TX as the Main RX is
connected to. This splitter function enables multiple RXs to display the same TX video.

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 a CATx cable (straight, EIA 568B) to directly connect TX/RX as a pair connection, or connect to IGMP
enabled 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. Adjust TX/RX D/A switch for HDMI/DVI installation. Connect TX/RX to video source/screen.
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 1st connected RX”or “Copy EDID from RX IP”and then perform
step 4.3 or 4.4.
Or you can change and use the TX built-in EDID as step 4.5:
4.1Press 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
