CONTROLS
Manual Switching
Momentarily press the SOURCE/AUTO-3s button to switch to the next available input. The
corresponding LED will illuminate green. If Auto Switching is enabled, this will turn it off
and the AUTO LED will extinguish.
Auto Switching
Press and hold the SOURCE/AUTO-3s button for at least 3 seconds to turn Auto Switching
on. The AUTO LED will illuminate green. Auto Switching abides by the following principles:
New Input: When a new source is detected, the unit will automatically switch to the
new input.
Rebooting: The unit saves its status and will automatically enter the last mode used,
in the event that power is lost. If the last displayed signal is still available, the unit
will switch to that input. Otherwise, the unit will scan the inputs in order (1-4), then
will switch to the first input found.
Signal Loss: If the currently displayed signal is lost, the unit will scan the inputs in
order (1-4), then will switch to the first input found.
Volume Control
Use the VOLUME UP and VOLUME DOWN buttons to adjust the output volume level.
Output Resolution Selection
Momentarily press the OUTPUT RES button to display the
OSD Resolution Menu. Momentarily press the OUTPUT RES
button again to move the highlight down the list. Once the
desired output resolution is highlighted, press and hold the
OUTPUT RES button for at least 2 seconds to set the output
resolution to the highlighted value.

232 control software, as well as to pass RS-232 control signals through to a third party
HDBaseT™ matrix or receiver (not included). It supports serial communications rates of
2400, 4800, 9600 (default), 19200, 38400, 57600, or 115200 baud.
To use RS-232 control, plug one end of the included RS-232 cable in to the RS232 Euroblock
connector on the switch, then plug the other end into an available serial port on your
computer. The RS-232 communications protocol is as follows:
Baud Rate: 9600 (default)
Data Bits: 8
Stop Bits: 1
Parity: None
Download and install a third party RS-232 control software, such as
CommWatch.exe, whose interface is shown below as an example.
