The 30-inch, USB to RS232 bridge cable adapter permits connection of Meade ETX-, DS2000-, LX90- and LX200-Series telescopes to a PC via USB port. Many new laptop computers do not have RS232 serial ports and offer the faster USB ports instead. With this bridge cable, you can make the USB connection anyway. Driver software compatible with Windows 98SE, ME, 2000 or XP is included. This software essentially creates a virtual serial port on your computer. To complete the connection, however, you’ll also need a Meade connector cable set.
