Introduction The 3e-250 Bluetooth to RS-232 Cordless Adapter is a Plug and Play adapter that allows you to use your RS-232 (serial) port to communicate wirelessly between multiple pieces of equipment. In itself, the 3e-250 requires no installation of software or drivers on the host machine. It doesn't initiate communications, but simply acts as a substitute for a wired serial connection.
