RS232 Control
HDMI-SWISS has a built in RS232 controller to pre-load and store
RS232 command for controlling the sink device power on/off the
commands are triggered by detecting input signal status.
To configure the unit’s ability to do this, connect a PC to HDMI-SWISS
via a (RS232 3pins) UART-to-USB cable, check which port on the
computer the RS232 cable is connected to in the device manager. Run
the LINK PORT CONFIGURATION TOOL software and set the
connection parameters correctly before sending any commands to
HDMI-SWISS. Set the baud rate to 57600 and choose the correct port
in the pull-down menu. Then press Connect. Once connected you are
able to set the RS232 output port commands and the relay mode.
LINK PORT CONFIGURATION TOOL menus are described below:
Baud rate: Choose the correct baud rate according to the sink
device, then click “Connect” to connect with the device.
Note: This might be different than the setting of 57600 above and
is determined by the sink device you are connecting to.
Power on: Pre-load and store the command for “power on” to a
sink device, then click “Send” to send and store it on the device.
Power off: Pre-load and store the command for “power off” to a
sink device, then click “Send” to send and store it on the device.
Note: If the sink device requires hex commands, make sure the
Hex box is checked.
Delay: Set delay time (0~30minutes) the sink device will power off
automatically after it cannot detect the input signal, click “set” to
take effect.
Set Terminator: Select the command ending after each RS232

9
command that you are sending from the HDMI-SWISS to the sink
device. Then click “Set” to take effect.
Set Relay Mode: Set relay mode for the sink device.
Latch –relay closes and latches when it is triggered;
Momentary –only closes for a moment and then opens after it is
triggered.
Then click “Set” to take effect.

Troubleshooting
1. No Power
•Ensure the power is on.
•Ensure you use the power adapter provided in the package.
2. No Picture or Video Flash
•Ensure all devices are on, and all cables are qualified and
connected properly.
•Ensure all the cables’ length are within the maximum distance (refer
to Specification table).
•Ensure the LED indicator is normal.
•When connecting source to display directly, ensure them can work
properly.
•Ensure the input resolution is supported by the device.
3. No Audio
•Set EDID switch to fix EDID (see “EDID Presets” section), then try.
•For analog audio output, ensure output audio format of source
device is PCM 2.0.
•For digital S/PDIF coaxial audio output，ensure output audio format
of source device is 5.1 channel or below.
4. RE LAY Invalid
Ensure RELAY is set to correct trigger mode, Latch or Momentary.
5. RS232 Output Commands Invalid
•Ensure the commands set via UART port configuration tool are
correct.
•Check the commands case.
