Chapter 4: Operation
4. Operation
4.1 Front-Panel Buttons
AVS-HDB-WPTX has a channel switching button on the front panel, through which
users can switch input source signals.
It supports both manual switching and auto switching. (The default setting is Auto
switching.) Press and hold the switching button for 3 seconds or send command
“50770% “ and “50771%” to switch between the two modes.
Switching modes:
• Auto switching mode: In this mode, the indicator will light green, and
AVS-HDB-WPTX will recognize the last connected source device as the input source
automatically.
• Disconnect the present source device, and it will deliver the other source signal (if
there is an input signal on the other source).
• Manual switching mode: In this mode, the indicator will remain off. Press the
switching button to select the input source, it will switch circularly between HDMI and
VGA. Or switch it by sending RS-232 commands. The indicator of the selected input
source will light green.
4.2 RS-232 Control
RS-232 can be transmitted bi-directionally between AVS-HDB-WPTX and AVS-HDB-RX,
so it can control a third-party RS-232 device locally or control an AVS-HDB-WPTX from
remotely. To control a third-party RS-232 device, set the baud rate of this device to
2400, 4800, 9600, 19200, 38400, 57600, or 115200.
