Pin 1: Connects to the 2 pin of the male 9-pin connector (Tx).
Pin 2: Connects to the 5 pin of the male 9-pin connector (Gnd).
Pin 3: Connects to the 3 pin of the male 9-pin connector (Rx).
2. Install the serial driver on the computer, if needed.
3. Once properly connected, you can control the 4x1 HDMI selection switch by
sending RS232 command codes.

Figure 3: System diagram
Auto-switching function
The 4x1 HDMI selection switch comes with an auto-switching function. The switch
continually checks for an input signal. Once detected, it automatically switches.
Additionally, it can be controlled from the front panel, IR remote, or RS232 integration.
HDMI Signal

HDMI 4x1 Selection Switcher User Guide 7
The auto-switching mode follows the principles listed below.
General switching principle
When there is no new source device connected to the input port, the 4x1 HDMI
selection switcher detects the input ports one by one and from input 1 to input 4. Input
1 has the highest priority, and the input 4 has the lowest. This means that if input 1 is
available, the 4x1 HDMI selection switcher will choose input 1. If not, it will choose the
next input available for output.
New input principle
When detecting a new input signal, the 4x1 HDMI selection switch switches to the new
signal automatically. For example, if the 4x1 HDMI selection switch is displaying a
signal from input 3, it will switch to input 4 when you connect a new source to this
input.
Power rebooting principle
When rebooting, the 4x1 HDMI selection switcher remembers its last display and
switching mode by using its power fail memory function. However, the 4x1 HDMI
selection switch will detect the HDMI input signal again with priority from input 1 to
input 4 once it can no longer detect the last input. This can occur if you remove the last
displaying signal while the switch is powered off.
Signal removing principle
When the current display signal is removed, the 4x1 HDMI selection switch selects the
HDMI input signal with the highest priority (Input 1 to input 4).
Examples
•Connect input 2 and input 4 to source devices. Press and hold the front key
INPUT 1 for three seconds. The LED indicator Auto-SW illuminates. The 4x1
HDMI selection switch starts running in auto-switching mode.
•The 4x1 HDMI selection switch detects the signal from input 1 to input 4 one by
one. When it detects that input 1 is no longer available, it then looks to detect
input 2. If it detects that input 2 has a higher priority and is available, it will select
input 2 for output. The LED indicator of INPUT 2 on the front panel will illuminate.
•Connect input 3 with a source device. The 4x1 HDMI selection switch chooses
input 3 for output, since this is a new source.
•Remove the source device from input 3. The 4x1 HDMI selection switch again
detects from input 1 to input 4. When it detects that input 2 has the highest priority
and is available, it again chooses input 2 for output.
•Remove power from the 4x1 HDMI selection switch, and then reboot. As the 4x1
HDMI selection switcher goes into auto-switching mode, it chooses input 2 for
output.

8 HDMI 4x1 Selection Switcher User Guide
Auto-switching mode and manual-switching mode can be set by pressing the input 1
button, or by entering an RS232 command. Auto-switching mode is the factory default.
The operations are listed below.
Button control
Pressing INPUT 1 for three seconds toggles the switch between auto-switching mode
and manual-switching mode. The Auto-SW LED designates which mode it is currently
in.
RS232 control
Sending the RS232 command “602%” sets the switch to Manual mode and turns off
the Auto-SW LED. Sending the RS232 command “601%” sets the switch to Auto mode
and the Auto-SW LED turns on.

Troubleshooting and maintenance
•If the POWER indicator does not work, ensure the power supply is connected
properly. Check to be sure that a circuit breaker has not tripped and that power is
available. If power is available and the splitter will not power on, contact Customer
Service for assistance.
•No image on display.
•Ensure that the display device has been set to the correct input.
•Ensure that the HDMI cables used for both the input source and the output
displays are properly connected and are working. Test the HDMI cables
directly from a source to display and ensure their operation.
•Ensure proper grounding of the power supply.
•If the switch fails to respond to commands from the RS232, IR, or the front panel,
contact Customer Service.
