While many of the new spectrophotometers on the market today are equipped with a USB cable to connect to the PC, most of the older models still use a serial communications cable to communicate with the PC. USB to serial adapter cables can bridge the gap for those PC's that do not have a serial port installed on their PC. There are many such devices available, but not all work well with the high demands of data transfer of a color spectrophotometer--especially not on a 64-bit PC.
