Serial Adapters

Bluetooth RS-232 9 Pin Dongle with up to 230kbps baud rate acts as a cable replacement when connecting to serial printers, serial scanners, or other serial device to a computer up 100 meters (300ft) from the remote.

With its small size the Bluetooth dongle is ideal for use with various applications where PDA or laptops could communicate wireless with sensors, robotics, radio or other devices.
