We have 8.1 up with a logitech webcam on the end of an astronomical telescope. It works fine with the computer next to the telescope but we want the computer 30 metres away. Is there any way I can do this with usb? With a single USB cable you are out of luck. The USB design is limited to about 4 to 5 meters per cable.
Possibly this item from Cyberguys would be of help. Notice it can be daisy chained up to 80 ft. USB ACTIVE EXTENSION CABLE, 16FT The USB Active Extension Cable ensures the signal quality of your USB cable and it ensures that the signal meets the USB's Electrical & Timing Specifications. Using passive cables to entend the length of a USB cable can result in signal errors and is not recommended. The USB Active Extension Cable acts as a transparent USB Hub and buffers both upstream and downstream data traffic. The cable comes in both 8- and 16-foot lengths and can be daisy chained in order to reach up to 80 feet in length. http://www.cyberguys.com/ Item# 131 0950 $ 22.42 each *************************************************** Powered by SuSE Linux 8.0 Professional KDE 3.0.0 KMail 1.4 This is a Microsoft-free computer Bryan S.
