TROUBLESHOOTING

5.Troubleshooting

Monitor

There isn’t a picture.

Check the power supply connection at the local and remote unit. Is the Power (Red LED) at the Local unit illuminated (see page 29)? If not, the internal power-supply may be damaged or there may be an internal error.

Check that the Interconnection cable is connected at the Local Unit and the Remote Unit. Is the Link Status LED illuminated (see page 29)? If not, there may be a problem with the Interconnection cable:

Are there Errors through data transmission over CATX Cable (Cable too long, too high attenuation or too much EMI interference )? Is the Data Error LED illuminated or blinking (see page 29)? If yes, check cable length and environment.

Video Okay LED is dark: CPU does not provide a video signal – Check settings of the graphic card. Try out, connecting a monitor to the local output, to see, whether there is a signal or not.

‘Stepping’ pictures on displaying movies

On high resolutions, the amount of data transmitted each second expires the capability of the data link. Therefore the data have to be reduced before transmitting. This is done in a first step by a so called RLE (=Run Length Encoding) algorithm. If this (loss less) compression does not reach the required amount, frames are dropped: The frame actually transmitted is transmitted completely even if the graphic card generates a new frame. This new frame is discarded. Because of this behaviour, the count of frames per second (fps) may be reduced to a value, where ‘stepping’ pictures are seen.

How to solve the problem: Please use a lower resolution, which is slightly higher than the resolution of the recorded movie. Please see, that most (actual) movies do have only a low resolution of approx. 720x480 (NTSC) or 704x576 (PAL) or even 320x256 (VHS). If the monitor provides a higher resolution, it may provide the scaling of the pictures. The picture quality is the same, if the monitor or the CPU does the scaling.

How to solve the problem: Set the color depth to 16/24Bit AUTOSELECT. On moving pictures, the human eye is not able, to see differences between so many colors. A reduction to 16Bit reduces the amount of data without (visible) effects.

PS2-Keyboard

The PC boots fine with no error messages but the keyboard does not work at all

Wrong cable plugged in, keyboard and mouse cables reversed.
