Lathem USB Active Extension Cable, 16 ft. The specification for USB states that the maximum length of a USB cable is 5 meters (16 feet). As a result, you cannot extend the distance of your USB device more than 16 feet without using a USB active extension cable (also known as a USB repeater cable). This cable contains active electronics which boost the USB signal for maximum reliability and performance over extended distances. Caution: Each active extension cable uses a portion of the power supplied via the USB cable and may cause a dim display or malfunction of the Lathem TouchStation because this device gets its power from the same USB cable. Lathem has tested this particular cable and has achieved acceptable performance with up to 4 cables (64 feet total). However, your system's performance will be determined by many factors including the power output of your PC's USB port.
