Product details

The Celestron USB-to-RS-232 Converter Cable enables a seamless connection between older serial Celestron telescope cables and modern computers or laptops via a USB port. This specially designed adapter cable is ideal for use with the Celestron NexStar RS-232 Cable (#93920) and the Programming Cable (#93922).
