6. WEB Instruction:
6.1. Change the IP address of your PC
Before configuring the encoder through the web GUI, it is necessary to configure the IP
address of the computer used to setup the encoder (mainly to ensure that the computer
and the encoder are set in the same network segment and can communicate with each
other).
1). Open the ‘Network & Internet Settings’ and set the computer's IP address：

8
2). Choose to use Static IP, with the IP address set to 196.168.1.x (x ranges from 0 to
254, but cannot be consistent with the device's IP address [192.168.1.168]).
3). Subnet mask set to 255.255.255.0
4). Gateway set to 192.168.1.1
5) . Enter the encoder's default IP address (192.168.1.168) in a web browser to access
the encoder’s configuration web GUI.
Way to enter the device login interface:
(1) If the encoder’s IP address has been customized, enter the encoder’s customized IP
address in a web browser to access the encoder’s configuration web GUI.

9
1) To enter and access the user configuration interface, enter the correct user name and
password (Default username and password: admin).
Note: Encoder Static default IP: 192.168.1.168 (device and computer directly connected
by network cable).
If the encoder is connected to a router, your router may utilize DHCP and assign your
encoder an IP address. You can view the assigned IP address of the encoder by using the
‘Switch’ front panel button to cycle to the third page on the LCD screen of the encoder.
6.2. System Setting:
1) System Information
●In the "System" tab, you can view the Device name, Device SN, Device type, Running
time, CPU usage, Memory usage, Device temperature, HDMI status, and Version in real
time.
●The device name can be modified within 32 bytes or characters. After modification is
complete, press “Save” to apply the changes.

10
2) Language Switching
● In the "System" tab, the language of the interface can be switched from English (US)
to Chinese via the drop-down menu.
3) Channel
● Through channel configuration, the user can create a one-to-many broadcast or many-
to-many video matrix.
● The multicast channel of the encoder should be configured in the ‘System’ tab prior to
being used with a decoder. The decoder will need to match the encoder’s multicast
channel in order to display the encoder’s source signal.
(Note: Two encoders cannot use the same multicast channel otherwise channel conflict
will be caused).
4) Stream Switch

11
● “Stream” checkbox: When the "Stream" checkbox is selected, the encoder will begin
to output a video stream; when it is not selected, the encoder will not output a stream
Note: (1) The function of “Switch” checkbox is the same as the front panel “Stream”
button of the encoder. When the “Stream” button is green, the video stream is output;
when the button is red, the encoder stops output.
(2) Press and hold the ‘Stream’ front panel button for 2 seconds and the ‘Stream’
checkbox will update accordingly on the web GUI in real time.
● "Stream Button" checkbox: When the "Stream Button" checkbox is selected, the
"Stream" button on the product becomes disabled.
● "Multicast to Decoder (Rx)" checkbox: When the "Multicast to Decoder (Rx)"
checkbox is selected, the encoder begins to stream on the Channel designated in the
‘Channel Choose” section of the web GUI; when the "Multicast to Decoder (Rx)”
checkbox is not selected, the encoder stops transmitting video streams on the
corresponding channel.
5) Upgrade Equipment
In the ‘Upgrade’ section of the ‘System’ tab, you can update your encoder’s firmware,
upload new EDID information and change your ‘No Input Signal’ image.
● Firmware upgrade:
Ø Select "Firmware" from the drop-down menu
Ø Click the ‘Browse’ button to locate the firmware file (bin format). After
selecting the correct .bin firmware file, click the ‘Upgrade’ button to apply the
firmware update
Ø You can view the current firmware version in the ‘System Info’ section of the
‘System’ tab, under ‘Version’.
● EDID upgrade:
Ø Select "EDID" from the drop-down menu
Ø Click the ‘Browse’ button to locate the EDID file. After selecting the correct
EDID file, click the ‘Upgrade’ button to apply the EDID update
Ø To view the encoder’s current EDID, enter the device's IP address + / edid.txt in
a web browser’s address bar. (example: 192.168.1.112/edid.txt)

12
Ø View HDMI Output EDID: To view the HDMI output device’s EDID
information, enter the encoder's IP address + /loop_edid.txt in a web browser
(example: http://192.168.1.112/loop_edid.txt)
Download the HDMI Output EDID: Enter the device's IP address +
/loop_edid.bin in a web browser’s address bar and you will download the HDMI
Output EDID information in a .bin file.
NOTE:(1) In order to successfully download an HDMI Output EDID file, the
corresponding display device must be powered on, set to the correct HDMI input
connected to the HDMI output port of the encoder.
(2) If the device is upgraded to a downloaded EDID file, it may cause the picture not
to be shown in the device if the signal conflicts with the new EDID file.
(3) If you are experiencing signal issues after upgrading the EDID file, restore
factory settings on the device.
● LOGO upgrade:
Ø Select "LOGO" from the drop-down menu
Ø Click the ‘Browse’ button to locate the logo file to be used. After selecting the
file, click the ‘Upgrade’ button to apply the logo update
6) Factory Default Reset
● After confirming you’d like to restore the encoder to factory default settings, pressing
the ‘Factory Default’ button in the ‘System Operation” section of the ‘System’ tab, will
restore factory Settings and all parameters will be restored to the original state.

13
7) Reboot Device
● The parameters set before pressing the ‘Reboot’ button will be saved when performing
a reboot;
● After pressing the ‘Reboot’ button, the web GUI and the device will be temporarily
offline. Afterwards, the encoder will automatically power on, restore network
connectivity and the web GUI will become accessible again.
8) User password
● The default password to access the web gui is - admin
● Please note that the web gui will ask for your login credentials again after changing
the password of the encoder
6.3. Network Configuration
2) In the "Network" tab, UDP, RTSP Port, IP Address, Subnet Mask, and Gateway fields
can be modified; After network configuration changes have been made, the device needs
to be restarted manually to take effect (system tab > reboot). *Note – Assigning the
encoder a static IP address (vs DHCP) will make it easier to access the web GUI
consistently.
3) Two video streaming protocols are provided: primary and sub-code streams of RTSP;
RTMP live streaming protocol.
4) RTSP Anonymous Access: Check the box to indicate that no login credentials are
required when viewing the stream. If the option is unchecked, users will need to input
web GUI’s login credentials to view the stream.
5) Default account and password: admin
6) Note: the modified IP address cannot be the same as any of the IP addresses assigned
to a device already on the network.

14
6.4. Audio configuration
Use the ‘Audio’ tab to configure your encoder’s audio settings.
• Audio
o HDMI – Default | The encoder will use the stream the audio from the
incoming HDMI signal
o ANALOG – Embedded | The encoder will embed audio from the 3-pin
phoenix analog port into the stream

15
• Sample – Auto | The encoder will automatically detect the incoming audio
sample rate and adjust the output stream accordingly
• Encoder: AAC | The encoder will use the AAC profile to encode audio
• Analog Vol: Used to adjust analog audio output volume | Default is 50, volume
range 0-100
● 1）ANALOG Embedding: Connect your desired analog audio source to the 3-pin
phoenix terminal via stereo to 3-pin phoenix cable. Access the ‘Audio’ tab via the web
GUI and select ‘Analog’ from the Audio drop-down menu.
