it will select the other source signal (if there is input signal on the other source).
Manual switching mode
In this mode, the indicator will remain off. Press the switching button to select input source, it
will alternate between HDMI and VGA. Or switch it by sending RS232 commands.
The indicator of the selected input source will illuminate green.
5.2. RS232 Control
As RS232 can be transmitted bi-directionally between AVG-HDWP70TX-B and AVG-HD402PR, it
is able to control a third party RS232 device locally or control the AVG-HDWP70TX-B from a
remote location. When controlling a third party RS232 device, the baud rate of this device can be
set to 2400, 4800, 9600, 19200, 38400, 57600 or 115200.
5.2.1. Installation/removal of the RS232 Control Software

HDWP70TX-B.
Removal Delete all the control software files in corresponding file path.
5.2.2. Basic Settings
First, connect theAVG-HDWP70TX-B with all input devices and output devices needed, then
connect it with a computer which has the installed RS232 control software. Double-click the
software icon to run this software.
Here we take the software CommWatch.exeas an example. The icon is shown as below:
The interface of the control software is showed as below:

Please set the parameters of COM number, baud rate, data bit, stop bit and the parity bit correctly,
then you are able to send commands in Command Sending Area.
