Bluetooth Serial Adapter
Serial RS232 or USB connections

This Bluetooth serial adaptor eliminates your conventional RS232 serial cables, providing an easy–to–use, invisible connection with superior freedom of movement. This tiny adaptor allows any device with a standard 9–pin serial port to communicate wirelessly.

You can communicate with another Bluetooth serial adaptor or other Bluetooth–enabled devices such as a robot controller, laptop computer, PDA or mobile phone.
