Log In

Method 1: Open the IE browser, enter the IP address on the OLED screen and enter the Web UI home page Default user name: admin Password: admin

note:If you cannot access the Web UI, please set the IP address of your PC to the SAME ethernet subnet according to the IP address displayed by the OLED.

Method 2: Open the login page through NDI® Studio Monitor

Find the NDI® source in Studio Monitor(download official website “”) and click the SETUP icon in the lower right corner, then you will be enter the Web UI interface directly.

Web UI and Control Interface Dashboard

The device information includes:

i:Device uptime (since power-on), video resolution and audio frequency of the currently input HDMI or SDI source (or format information of the decoded NDI® video stream).

ii:Device name (can display the current of the codec mode), equipment hardware serial number, version and firmware version (with the updated version to upgrade the system page), MAC address (the only and shall not modify), the equipment IP address (can be modified at any time in the web page), the local IP address (the IP address of the local PC or cell phone), disk space (flas hardware H disk space usage), real-time temperature of the main chip, and memory usage.

Network Setting

1. IP address setting
i:DHCP mode

Automatic Mode (DHCP) is used on lans with routers. When the device is started, the router dynamically assigns IP addresses to the device. If there is no router on the LAN, the default IP address of the device is

ii:Manual mode

In manual mode, enter the IP address, subnet mask, and gateway, and click the Manual button to switch to the manual mode. Be different from other IP addresses on the network. After the IP address is successfully changed, the device restarts and the WebUI switches to the new IP address.

2. NDI multicast Setting

When Multicast mode is turned on, which is the UDP (Multicast) delivery mode, it has a default Multicast address and a subnet mask. You can configure the address manually, and clicking Apply takes effect. Close the multicastThe transmission mode of TCP (Multi-Connection) is adopted. The default is to turn off multicast mode.


The coding page contains:

In NDI® encoding mode, users can flexibly set a variety of NDI® parameters, such as THE NDI® stream name, frame, frame rate, encoding volume, input source priority, Tally display switch, and optical switch.
In addition, one of the most important ancillary features is that you can convert and output any format you want without affecting the NDI® encoding. The converted format is output simultaneously through NDI, SDI OUT and HDMI OUT.

1. UpDownCross Conversion

Choose any format you want on the WebUI. No matter what format the video source input is, you can easily convert it to NDI®, SDI OUT, and HDMI OUT at the same time. Therefore, it can be said that format conversion and NDI® encoding can be carried out simultaneously. At this point, you have a box that integrates the NDI® encoder and the up and down converter.
This conversion does not change the image quality and turns green. If no conversion is required, select Auto, which is the same format as the input source. When the optical transceiver function is used, the format frequencies of both the sending and receiving devices must be integers or decimals.

2. NDI stream name

In encoding mode, you can change the NDI® stream name under the encoding TAB without having to reboot the device to distinguish between different NDI® encoders. The default stream name is: NDI-X.

3. Aspect ratio

You can define and change the NDI® stream aspect ration that supports five settings: source aspect ratio, 4:3, 16:9, 16:10, square.

4. Frame rate

Support 4 kinds of frame rate settings:
source frame rate, 1/2 frame rate, 1/3 frame rate, 1/4 frame rate.

5. Bit rate

When the bandwidth of the network is not ideal, the bit rate bandwidth of NDI® can be adjusted to a minimum of 20M.

6. Input source preference choose

Primary input confirmation of HDMI and SDI input sources.
The priority can be switched freely during NDI® encoding (when both SDI and HDMI are connected to the video source).

7. Tally LED switch

Program means bright red for Program broadcast, Preview means bright green for Preview. You can select the switch as required, and it is turned on by default.

8. Optical transceiver setting

Optical transceiver setting is to regard the device as an optical transceiver and use optical fibers for data transmission. It is necessary to send one transmission and receive one transmission to two devices, and both devices are in coding mode. First, select a device as the sender, log in to the web user interface (WebUI), locate the optical device on the coding page, and enable the select sending mode. Video format conversion and input source preference can be used to select frequency conversion and signal source respectively for optical signal transmission. Then, select another device as the receiver, log in to the WebUI of the receiver, enable the optical device Settings, and select the receiving mode. SDI OUT and HDMI OUT output optical signals. The same optical output can also be converted to video format, but it should be noted that the format frequency selected with the sender must be the same integer or decimal.

9. External audio embedded setting

LINE IN is a mix of embedded audio and NDI’s original audio. The volume of the main audio is used to adjust the volume of the original audio IN the NDI, and the volume of the embedded audio is used to adjust the volume of the embedded audio. This setting is applied to the Headset jack and THE NDI®. By default, the volume of the LINE IN audio is 0, and no embedded audio is output.



If you use this device as a decoder (OLED will display a decoder), you need to select the NDI® source to be decoded and the decoded NDI® source name and format will be displayed on the OLED screen.
Click the NUMBER of the NDI® signal source to be decoded (for example,  is the current NDI® signal source to be decoded). The output of SDI and HDMI is the decoded signal of the selected NDI® signal source.


1. Reset login password

To change the login password, click Apply. The new password takes effect upon the next login.

2. Restore factory settings

You can restore the device to the initial state but not the firmware version (the default IP address of the device is DHCP mode). If there is no router in the LAN that automatically assigns IP addresses, the IP address of the device will be changed to

Press and hold the reset key (in the pinhole of the front panel) and power on the device at the same time. At this time, you can see that the OLED displays “system recover”. Release the reset key to start the process of restoring the factory setting. When Tally is green, the factory setting is restored. It takes 20 minutes, please wait patiently.After recovery, please download the latest firmware upgrade on the official website.


Q. Why can't the device start?

A. Check whether the device power indicator (located on the right side of the chassis) and OLED screen are on, and restart again with the official power adapter; Do not turn off the upgrade page and power during device upgrade!!

Q. Why not log in to the Web UI?

A. Check whether the IP address of the device and the IP address of the computer are in the same network segment, and whether the IP address of the device conflicts with the IP address of other devices in the network segment; Check whether the network environment is good; Attempt to power down and restart the device.

Q. Why does the device IP address display

A. This is because the device is in the automatic IP acquisition mode in the network settings of the webui, but there is no router in the LAN connected to the device to assign an IP address to the device. At this time, change the computer IP to 192.168.8. * *, then log in to the Web UI, change the device to manually obtain the IP, fill in the address, subnet mask and gateway, and click [apply].

Q. Why is the image output from the device to the display device abnormal in color, sound or picture?

A. Try to restart the device in the Web UI system, or manually power off and restart.

Q. Why is the device output to the white screen of the display device

A. This is because the decoding device does not select which NDI source to solve. Try to log in to the Web UI, check whether the correct coding source is selected under the decoding column, click refresh list and select again.

Q. NDI® decoding is stuck and not smooth

If the NDI® decoding picture is not smooth and jammed, please turn multicast on or off to test the fluency of NDI® under the condition of ensuring a good network environment.
