3.3.14 Troubleshooting Guide
This program may malfunction sometimes due to a communication problem between the PC and
display or electromagnetic waves emitted from nearby electronic devices.
Issue Solution
The display you want to control
does not appear on the system
information chart.
1. Check the connection of the RS232C cable (check that the
cable is properly connected to appropriate serial port).
2. Check that another display with a duplicate ID is not
connected. Connecting displays with a duplicate ID can
cause the displays not to be shown due to data collision.
3. Check that the display ID is within the range of 0 and 99.
(Change the ID using the Display menu.)
For a display that supports the ID in a range of 0 to 99,
the ID should be set between 0 and 99.
The display you want to control
does not appear on the other
Control Info Grids.
Check that the display is powered on. (See the power status in
the system information chart.)
Ensure you select the input source the display is connected to.
The following message appears
repeatedly.
Check that the display you want to control is selected.
Displays power on or off at different
time from one another even though
On Time or Off Time is set.
Adjust the time on the PC to synchronize the time between the
connected displays.
The remote control does not work. The remote control may not work if the RS-232C cable is
removed or the program is closed abnormally while the Remote
Control function is Disable. To resolve this, run the program
again and set Remote Control to Enable.
