Display Control
To control a display (Projector, etc.) through pre-loaded RS232 commands, configure the RS232 port of the DCE-1 according to
the display parameters.
1.
Connect a PC to the DCE-1 according to section “Control the DCE-1”.
2.
Configure RS232 parameters of the DCE-1 with the serial port software according to the display parameters. For example:
set the correct baud rate, preload Power-ON and Power-OFF commands in string/hex (refer to the document “API Command
Set_DCE-1).
3.
Disconnect the PC from the DCE-1, and connect the display according to the diagram on page 6. The DCE-1 can
automatically execute RS232 commands to Power ON or OFF the connected projector and projection screen when an input
signal change is detected.
Troubleshooting
Power: Ensure all devices are powered on.
Indicator: Ensure all LED indicators of the DCE-1 are normal according to the user manual.
Devices: Ensure picture can be shown normally when directly connecting a source to a display device.
Cable: Plug the HDMI cable in and out or connect a different HDMI cable. Ensure the specific cable length is within the available
transmission range according to the Specifications Section.
EDID: There are multiple EDID presets depending on the EDID rotary switch setting. Please refer to the EDID Management Section
to ensure the display works properly.
Compatibility: Test other source and display devices to determine correct compatibility.
