CHAPTER 8: Troubleshooting

I get black & white instead of color video.

Your CPU probably needs to see monitor ID in order to boot into the correct video mode. Please contact Black Box Technical Support.

Microsoft Windows 3.x, 95, 98, or 2000, Windows Me, Windows NT, or Windows XP will only boot into a low-resolution graphics mode.

1.If your graphics card supports VESA DDC (Display Data Channel), configure the graphics driver by explicitly telling it which make and model of monitor you’re using, rather than letting the driver configure itself automatically (and probably erroneously) through DDC, which the Extender doesn’t support.

2.The CPU might need to see monitor ID in order to boot into the correct video mode. Please contact Black Box Technical Support.

Connecting a keyboard to the Remote Unit has an adverse effect on the remote video.

Try using a newer keyboard. (Some older keyboards require too high a current for the Remote Unit to properly drive the video signal.)

The Extender doesn’t seem to work correctly with my LCD panel.

Try reducing the refresh rate of the video signal that your graphics card is outputting. (The maximum refresh rates supported by most LCD panels are less than those supported by most monitors.)

8.1.7POWER

I don’t need to use keyboards in my application, but the Extender doesn’t work at all unless I have a keyboard line running from the Local Unit to the PC or KVM switch.

The Micro Extender’s Local Unit normally operates using the 5 volts of DC power that the attached CPU or KVM switch supplies on its keyboard and mouse ports. Even if you’re not using a keyboard or mouse, run a cable from the Local Unit’s CPU port to the keyboard port of the CPU or switch in order to power the Local Unit. If this is not possible, call Black Box Technical Support about getting an alternative power supply for the Local Unit.
