1. Introduction
2.2. RS232 Interface
Thank you for purchasing our Bluetooth serial adaptor. The 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 laptop computer, PDA or mobile phone.
