A communication system for exchanging data between an actuator system and an external device, e.g., an operation where the communication system in the form of a gateway and a codex interprets the information in the bidirectional data stream and communicates the information on both sides. The communication system is furthermore provided with an RFID circuit integrated in a handset. The RFIC circuit can communicate information about the gateway" s unique identification , also known as an MAC- address. This achieves easy connection of an external device to the actuator system without having to enter data manually.
