select options of Type 1, Type 2, Type 1 guest mode, Type 2 guest mode (default Type 2).
Note: Type 1 is mainly for Unicast application which user can dynamically link with any target RX.
Type 2 is mainly for Multicast application which TX will RS-232 link with all of connected RXs (default).
Type 1 guest mode is similar to type 1 but using PC to link with RX’s RS-232.
Type 2 guest mode is similar to type 2 but using PC to link with RX’s RS-232.
For details, please refer to “How to Use RS232 over IP” manual.
To define RS-232 parameters for Type 2

Enter RX Operation mode Web page ---> [Functions] ---> [Audio Output] ---> check “HDMI Audio
De-Embedder for the audio output to Line-Out. Click [Apply] to save the setting and reboot.
Multi-Screen Setting
The system supports Multi-Screen feature which is useful for PC with multiple screens. Each TX/RX can
define its associated 2nd, 3rd, 4th TX/RX IP. So, when the Main RX switches to a new TX, its associated RXs will
also be switched to that new TX’s associated TXs automatically.
Enter TX/RX Operation mode Web page ---> [Functions] ---> [Multi-Screen Setting] ---> then enter IP
address for the associated 2nd, 3rd, 4th TX/RX IP.

Installation
1. The system factory default Connection Method for RX is “First Available”, and TX is in Multicast mode with
its default Multicast IP which shown on the label. This means all of TXs will send packets with its default
Multicast IP (225.0.xxx.xxx), and all of RXs will find the first available TX for connection. Please refer to page
5 for how to change Connection Method.
2. Use a CAT6 UTP cable (straight, EIA 568B) to directly connect TX/RX as a pair connection, or connects to
IGMP enabled Gigabit Ethernet switch for the many TXs-to-many RXs installation.
Note: Each TX comes with individual factory default Multicast IP which shown on the unit label.
3. Connects RX HDMI-Out to screen by HDMI cable.
4. Assign a specific RX as the EDID Master. To do this, press and hold the [Mode] button of the specific RX unit
and power ON until Green LED blinking then release the [Mode] button. Then power ON other RX units
sequentially. In this step, RX’s Green LED will blink then ON, and Amber LED Off to indicate it is ready and
waiting for connecting with TX. (or refer to page 6 “To Copy EDID from this Video Output” to assign a
specific RX as EDID Master)
5. The following start-up messages will be displayed during RX powered on:
FW: 16-Jul-18 A6.2.5 ---> Firmware version
Local IP: 10.0.34.38 ---> RX’s IP address
MAC: 0020FExxxxxx ---> RX’s MAC address
Connection Method:
---> Possible messages are: “First Available”,
Multicast or TX IP, “OSD Transmitter List”,
“Direct Connection”.
Remote IP: 10.0.x.x / 225.0.x.x
---> Connecting target TX IP / Multicast IP.
6. If the HDMI input source is 4K2K then please refer to page 5 to enable TX/RX Jumbo Frame setting, and
set Ethernet Switch Jumbo Frame with minimum 8K bytes to get the best video quality.
7. Attach HDMI/DVI source to the TX’s HDMI-In. Then power ON the TX unit. The TX’s Green LED will blink
then ON to indicate ready and wait for connection with RX.
8. As long as TX/RX connection established, both of TX and RX Amber LED will start to blink indicating wait for
video input source (Green LED is ON).
9. If you are using PC as video source, it is recommended to check if the correct screen EDID shown on PC
graphic card control panel.
10. Activate video with audio source to TX, then check if all RXs are correctly displayed. In this step, both Green
and Amber LED should be ON to indicate the unit is ready and video source is also ready.
USB and KM over IP installation
11. Connects TX USB-B to PC, OS will detect a Generic USB Virtual Hub Device.
12. The system can support both “USB-over-IP” and “KM-over-IP”.
The USB-over-IP works as a Virtual 5-port HUB when connected to TX, it is compatible with most kind of
USB devices such as keyboard, mouse, Pen Drive, Touch Screen… The USB-over-IP connection can be
configured in “Active on link” (Sharing) mode or in “Active per request” (Exclusive) mode (default). In
“Active on link” mode, the maximum USB-over-IP connection for a TX is 5 due to the 5 ports of Virtual HUB.
Page 11
11
The KM-over-IP means that USB port will work as HID device only for keyboard/mouse emulation, the PC
don’t get BIOS “Keyboard Error” if there is no real keyboard attached during boot up. It is not necessary to
gain USB access right for the KM-over-IP port. The TX (PC) can be shared with multiple RXs for
keyboard/mouse access in KM-over-IP mode.
13. There are 4 USB-A ports on the RX. The factory default setting for the TX is both of USB-over-IP and
KM-over-IP enabled, all 4 USB ports of RX are in USB-over-IP mode (KM-over-IP disabled).
14. There are 2 methods to gain the access right for a USB-over-IP port:
14.1 Long press (3 sec.) the RX [Link button].
14.2 Press “U” key to toggle during Transmitter List OSD menu.
The RX display “Requesting USB” to indicate starting USB-over-IP connection, and message of “Starting USB”
will be displayed if it successfully gained the USB access right. Meanwhile, the previous USB Master unit will
show an OSD message of “USB Stopping”.

again to move the highlight arrow to the desired selection. The RX unit will be
re-booted.
RX OSD Connection Method Sub-Menu
From the OSD Main Menu, press [Link] button to move the highlight arrow to
[Connection Method]. Wait a few seconds, either Multicast or Unicast
Connection Method sub-menu will show up depending on the RX’s Casting
mode.
The Multicast RX supports 4 possible connection methods: First Available,
Multicast IP, Transmitter List, and Direct Connection, as the right picture:
The First Available means the RX will connect to the first available TX that it finds on the network.
The Multicast IP 225.0.100.000 means the RX will connect to the TX with the same Multicast IP.
The OSD Transmitter List means the RX will show up the available Transmitters for user to select when
<Hotkey> <Hotkey> is pressed.
The Direct Connection means the RX will connect to a specific TX as a pair connection.
The Unicast RX supports 3 possible connection methods: OSD Transmitter List,
Dedicated TX IP, and Direct Connection, as the right picture:
Press the [Link] button to move the highlight arrow to the desired selection
and wait a while to confirm the selection.
Please note the Sub-Menu only provide selection, the Multicast IP or TX
IP can only be changed by the Web page setting.
RX OSD Transmitter List
Attach a keyboard to the RX’s any USB port, press <hotkey> <hotkey>. The
OSD List with maximum 8 Transmitters will be shown, as the right-hand
Page 12
