TROUBLESHOOTING

I can’t select the video mode I need.

For non-standard resolutions, choose the monitor manually through the operating system, and set to ignore DDC. Contact Technical Support if you have problems selecting your required graphics mode.

Can the extender be used with RGB video?

Yes.

4.2USB

Why does the Extender stop working when I attach a USB hub to the Remote unit?

If additional USB hubs are attached to the extender, the maximum extension distance will be reduced (due to the delay imposed by each hub). For each connected hub, you may lose up to 10m of extension distance. Any USB device to which additional USB peripherals may be attached is a USB hub (e.g. an Apple® USB keyboard).

Will the USB Micro Extender work with USB 2.0?

The extender will operate perfectly through USB 2.0 Host Controllers. However, the speed will be restricted to that of a USB 1.1 hub (12Mb/s). Devices that are USB 2.0 compliant will operate if they are backwards compatible with USB 1.1. If you have a device that demands the high-speed mode of USB 2.0 then it will not be compatible with the USB Micro Extender.

Is the USB Micro Extender compatible with all USB devices?

This product range extends the distance at which USB peripherals may be operated by making full use of the bus timeout period allowed by the USB protocol. The extender should be compatible with the majority (but not all) of CPU USB Host Controllers and USB peripherals on the market.

Extended USB devices are unstable and ‘drop out’.

Check that the interconnect cable is not routed near power lines or other sources of electrical interference. Use shielded STP/FTP cable instead of UTP cable and ensure the shield connection is maintained between the Extender units. Check system grounding.

The extension distance is too great for your CPU/USB device combination. Try reducing the interconnection cable length if possible.

Some of my USB devices do not operate over the full range.

The maximum extension range is nominally 150ft (50m). In practice, the maximum distance achievable may be between 120ft (40m) and 180ft (60m) depending on your system and USB devices. Adding external USB hubs may decrease the maximum extension distance by up to 30ft (10m) for each hub added. Adding bus- powered hubs in front of the Local Unit is not recommended.
