TROUBLESHOOTING

4.5General Questions

The green power LED is not lit when I connect my Local Unit to my USB hub.

Local Units normally take power from the USB connection to the computer. Local Units may require an external 5V PSU:

-If the CPU/hub cannot provide sufficient power through the USB connection.

-For video only applications.

Contact Technical Support for details of a suitable PSU.

Is it possible to use a cable length longer than 150ft (50m)?

The maximum extension distance is nominally 150ft (50m). Some systems may extend up to 180ft (60m) and others only 120ft (40m). Once the system range limit is reached, USB operation will cease or become erratic. For maximum extension distance, avoid connecting additional USB hubs to the system.

Which interconnection cable is best?

In electrically ‘quiet’ environments, UTP cable will give the best quality video over long distances because it has less capacitance per unit length. However, it is more prone to electrical noise and interference. In environments where this is likely to be a problem, use STP/FTP cable, ensuring that the shield connection is maintained between the Extender units.

Can I use CATx patch cables?

Yes, but to ensure maximum data integrity, use as few as possible. The maximum patch cable length at each end of the link should be limited to 9ft (3m).

Can the extender system be used between buildings?

No. Ground loops could damage the extender system and attached equipment.

Can multiple Local/Remote Units be used by swapping the interconnection cable?

Local units provide a transparent USB link, so it is possible to swap or switch the Local-Remote interconnection to create a matrix-switch system. Please call Technical Support before deploying such a system.

Can the extender be connected into our network?

Absolutely not. Regardless of the cable similarities, the data signals and voltages used by the extender are different to those used by Ethernet and other types of networks. Connecting the extender to a LAN hub, switch, repeater, or other network device, or exposing it to the signal levels present on network data lines may damage the extender and other devices.
