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.
