Troubleshooting
If you experience problems when installing or using the X2 Multi Screen modules, please check through this section for a possible solution. If your problem is not listed here and you cannot resolve the issue, then please refer to the ‘Getting assistance’ section.
Video image at the REMOTE module is distorted or shadows appear to the right of displayed objects.
Adjustments are required to compensate for the length of the twisted pair cable being used. If video problems persist:
•Please refer to the ‘Image controls - sharpness and brightness’ section in the ‘Special Configuration’ chapter.
•If the overall video image is ‘fuzzy’ and/or has coloured shadows you may need to make skew adjustments. This procedure allows you to finely tune the red, green and blue video signal timings to overcome most colour separation problems. Please refer to the ‘Skew adjustment’ section in the ‘Special Configuration’ chapter.
No video image is received at the REMOTE module.
•Check that the power/activity indicators are lit on the LOCAL and REMOTE modules - if they are not, then there is a power problem. The MS2 LOCAL module gains its power either from the computer’s keyboard socket or by using an optional power adapter. The MS4 LOCAL module requires power from its supplied power adapter.
When keys are pressed or the mouse is moved, check that the indicators flicker – if they do not respond then there could be a twisted pair link problem or a problem with one of the modules.
•Check that multiple link cables are correctly connected only between the corresponding ports on the LOCAL and REMOTE modules and do not cross over to other ports.
•Check that each link cable is wired correctly as per the diagram in the ‘Skew adjustment’ section in the ‘Special Configuration’ chapter.
•If possible, try using an alternative twisted pair link connection between the modules. Ensure that all of the link cables are of the same length and have the same twist characteristics - it is not possible to adjust only one video channel, they are all adjusted together.
•If the sharpness control is set too high, the monitor may not be able to display a picture. Try reinstating the factory default sharpness settings. Please refer to the ‘Image controls - sharpness and brightness’ section in the ‘Special Configuration’ chapter.
•Temporarily disconnect the video link to the LOCAL module, connect a monitor directly to the computer video port and check for a correct video image output.
The keyboard indicators are flashing between the Caps Lock and the Num Lock/Scroll Lock and the computer does not respond to any key- board or mouse inputs.
•The modules are currently locked and require a valid password to be entered. Please refer to the section ‘Locking and unlocking the system’ for details.
Power is applied via the power supply but the REMOTE module opera- tion has stopped.
•Each module has an internal automatic
The on-screen mouse pointer does not respond to mouse movements
•The mouse connection may have been interrupted. Either, reboot the system and
Sound from the microphone cannot be heard or is very quiet
•Check the setting of LOCAL switch 3 - if a microphone is connected at the REMOTE module, the switch should be set OFF.
Sound input from the stereo line input is distorted (‘tinny’ sounding) and only one channel is working
•Check the setting of LOCAL switch 3 - if a stereo line input is connected at the REMOTE module, the switch should be set ON.
