6. Web GUI User Guide
The wall plate can be controlled by Web GUI. The operation method is shown as below: Step 1: Get the current IP Address. The default IP address is 192.168.0.200 (when the system is not connected to a router). You can get the current switch IP address via API commands controlSend the ASCII command “r ip addr” through a Serial Command tool, then you’ll get the current IP address (The IP address is variable, depending on what the specific machine returns). For the details of API commands, please refer to “9. API Commands Control”.
Step 2: Connect the DANTE port of the wall plate to a Switch with an UTP cable. Step 3: Connect the PC to the same Switch with an UTP cable, and set the IP address of the PC to be in the same network segment with the wall plate. Step 4: Input the current IP address of wall plate into your browser on the PC to enter Web GUI interface.

10 / 22

Bluetooth Receiver (RX) Pairing Mode: Click to select the pairing mode (Manual/Reconnect/Exclusive).
Manual: In this mode, user can connect Bluetooth source by pressing the front panel button. The “PAIR” LED will begin flashing to indicate that the VLDT- WP44AB is now visible to other Bluetooth sources and accepting pairings. This pairing period lasts the time (can be set from “Auto Off”) after which the “PAIR” LED will stop flashing and turn off and the VLDTWP44AB will disable its Bluetooth interface. If a successful pairing is made during the pairing period, the “PAIR” LED will stop flashing and solid on. To disconnect a Bluetooth source from the VLDT-WP44AB, press and hold the front panel button for 3 seconds and then release it. The “PAIR” LED will turn off, and the connection will be reset. Now another device can be connected by repeating the pairing process.
Reconnect: In this mode, the VLDT-WP44AB maintains a pool of the last 8 paired sources and any previously paired source on that list will be permitted to reconnect when in range of the VLDT-WP44AB without requiring the front panel button to be pressed. The user simply selects the VLDT-WP44AB friendly name on their source device. Any new sources that are paired are added to the paired source list. If the list already full, a random source from the list will be removed and the new source added in its place.
Exclusive: This mode is intended for restricted use and works similarly in operation to reconnect mode. However, rather than allow any known source from the pairing list to reconnect, only a specific source can be used with this VLDT-WP44AB. To setup a source as the exclusive source, set the VLDT-WP44AB to “Exclusive” mode, clear the pairing list, and then pair the desired exclusive source to the unit. Only this exclusive source will be allowed to reconnect to this VLDT-WP44AB when in range. As with the reconnect mode, reconnection is done without requiring the front panel button to be pressed by simply selecting this VLDTWP44AB on their smart device. Once the VLDT-WP44AB has been associated with a source, both the front panel pair button and the API command sent via the network are disabled and will have no effect. To connect a different source, either pairing list must be cleared or the pairing mode needs to be changed. Auto Off: Click to select the waiting time (Off/30s/60s/User Defined, with a maximum of 1000s) for Bluetooth device connection. This function is only valid in Manual mode. If there is no Bluetooth device connected within the set time, the Bluetooth function will be turned off. This function can be woken up by short pressing the Bluetooth button. Note: If selecting “Off/30s/60s”, it will take effect immediately; If selecting “User Defined”, user need to manually input the time in the input box, and then click “Save” to take effect. Paired Sources: Check to select the desired paired source, then the “disconnect” behind the paired source will turn to “connect”. Up to 8 paired source records are supported. Clicking “Clear All” will clear all the paired sources, and the connected paired source need to be disconnected before clearing. Bluetooth Receiver (TX) First Priority: Click to select the Bluetooth audio coding format priority (APTX- LL/APTXHD), if both source and device support APTX-HD and APTX-LL formats. Auto Connect: Click Off/On to turn off/on the auto connection function. If you select “On” and click “Search”, then the Bluetooth device with the strongest signal will be searched and connected automatically. Paired Devices: Paired devices list. Check to select the desired paired device, then the “disconnect” behind the paired device will turn to “connect”. Clicking “Clear All” will clear all the paired devices, and the connected paired device need to be disconnected before clearing. Available Devices: Available devices list. When none of the devices in the paired devices list are connected, the selected device in the available devices list will move to the paired devices list.

Network Page
Network Configuration: Select to set the IP Mode (DHCP/Static). When Static is selected, you can manually set the IP Address, Subnet Mask, Gateway, Telnet Port and Domain Name as required, then click “Save” to take effect. When DHCP is selected, the system will search and fill the IP Address with the one assigned by the router automatically. Note: The Domain Name “VLDT- WP44AB.local” can be used to login the Web GUI. System Page
Account Passwords: You can modify the login password for User and Admin. After setting up, click “Save” to take effect. System Utilities Front Panel Buttons: Check to select “Front Panel Buttons”, then the front panel buttons are available, otherwise, the front panel buttons are unavailable. Reboot: Click “Reboot” to reboot the wall plate. Restore Factory: Click this button to restore the wall plate to factory settings. Restore Factory (including Network): Click this button to restore the wall plate including the Network to factory settings. Export Settings: Click this button to export configuration files. Import Settings: Click this button to import configuration files. Firmware Update: You can update the software of MCU and Web. Click “Choose File” to select the update file, then click “Update” to start update. When the progress bar reaches 100%, the update is complete.

7. API Commands Control

The wall plate also supports API commands control. First, please connect the wall plate and PC in either of following two methods. Method 1: Connect the DANTE port of the wall plate to a Switch. Then connect the PC to the same Switch with an UTP cable, and set the IP address of the PC to be in the same network segment with the wall plate. Method 2: Connect the Service port of the wall plate to a PC. Then open a Serial Command tool on PC to send ASCII commands to control the wall plate. The ASCII command list about the wall plate is shown as below.
