The Just Add Power WP2 (2-gang wallplate) and WP4 (4-gang wallplate) have both HDMI and VGA inputs.

There is a toggle switch on the front of each unit that is used to choose VGA or HDMI.

To enable auto-detection between the VGA and HDMI ports, apply this command through the Console API on the web interface of the Wallplate Transmitter:

astparam s v_input_select detect_sync;astparam save;reboot

Auto-detection follows these rules:

• First source (HDMI/VGA) to be connected will be the active source
• When a second source is connected it will not be displayed
• When the active source is disconnected, the second source becomes the active source (~5 seconds)
• When the toggle switch is moved, it will override the auto-detection

To return the device to standard settings (toggle switch only):

astparam s v_input_select;astparam save;reboot
