| This adapter allows you to connect your Celestron NexStar, GPS, CPC, or CGE computerized telescope to your PC through a high speed USB port, rather than through a slower serial port. This is particularly useful with the laptop computers that most astronomers use to control their scopes in the field, as these portable computers now rarely include a DB-9 or DB-25 serial port. The USB adapter includes a short (29”) cable with a DB-9 connector at one end and a USB connector at the other. The DB-9 end of the USB cable is designed to mate with the DB-9 connector on the Celestron #CABLEP GPS/CGE programming cable and #CABLEN25 NexStar cables normally used to connect a Celestron scope to a computer. The USB end of the cable plugs into your computer. A CD-ROM is included that contains the necessary software program your computer needs to convert the serial signals to and from the scope to USB format signals that the computer and computer control programs can recognize. |
