• Central node launch node
• Wireless module frequency band
• Wireless module transmit power

The configuration items on the WEB interface are shown in the red box in the following figure:

Password

The pairing key is a text input box used to set the password used for the control software networking. The transmitting node and the central node with the same key can establish a wireless link. The configuration that the pairing key can receive is hexadecimal data, up to 64, and it must be an even number.

Wireless Module IP Address

The wireless module address is a text input box used to set the IP address of the wireless video transmission system control software. The IP address uses dotted decimal mode.

Wireless Module Working Mode

The working mode of the wireless module is two radio buttons, which are used to set whether the control software is the central node or the transmitting node. The networking mode of the wireless video transmission system control software is a star-type networking mode, which requires at least one central node and no more than 16 transmitting nodes.

Wireless Module Frequency Band

Wireless module frequency band used to set the working frequency band of the control software. The central node and the transmitting node have different configurations for the frequency band.

Transmit Power of the Wireless Module

The transmit power is a drop-down list used to select the transmit power of the wireless video transmission system control software.

Uplink and Downlink Allocation

The uplink and downlink allocation is a single selection box used to select the ratio of the uplink and downlink of the wireless channel. When the wireless link is established, different channels are used for uplink and downlink data transmission. The ratio of the channels used in the uplink and downlink is determined by this configuration item. This configuration item of uplink and downlink allocation is only available on the central node.

The description of each option is as follows:

• 1 Down4Up: 20% of the channels are used for downlink transmission, and 80% of the channels are used for uplink transmission.
• 2Down3Up: 40% of the channel is used for downlink transmission, and 60% of the channel is used for uplink transmission.
• 3Down2Up: 60% of the channel is used for downlink transmission, and 40% of the channel is used for uplink transmission.
• 4DownlUp: 80% of the channels are used for downlink transmission, and 20% of the channels are used for uplink transmission.

Transmission Bandwidth

The transmission bandwidth is a drop-down list for selecting the frequency width of the wireless video transmission system control software when it is working. The available frequency widths are 1.4MHz, 3MHz, 5MHz, 10MHz, 20MHz. The configuration item of transmission bandwidth is only available on the central node.

Submit Configuration

After the configuration is modified, click the “Submit Configuration” button to make the configuration effective.

When you click the “Submit Configuration” button, the above configuration items will be checked, to see whether the input is empty and whether the input is legal.

When the configuration is modified, the wireless video transmission system control software will restart. After clicking the “Submit Configuration” button, the WEB interface will pop up a prompt box “Submitting the configuration will cause the system to restart. Please confirm whether to submit.” Please make sure that the module restart will not affect the data currently being transferred when submitting the configuration.

Please confirm when submitting the configuration, the wireless module restart will not affect the data being transmitted! !

After clicking the “Submit Configuration” button, the wireless video transmission system control software restarts. After the module is working stably, the web page needs to be refreshed.
