8、2.COMMUNICATION FLOW DESCRIPTION The DTR-5.2 uses Question, Command and Notification messages to have to communicate with a given HOST. This protocol is designed for point to point communication between a HOST and the DTR-5.2. 2.1.Command Communication Send a Command Message to the DTR-5.2 from the

9、HOST to change the system status. The DTR-5.2 will respond with a status message within 50msec. If DTR-5.2 does not respond within 50msec, the communication has failed. 2.2.Question Communication Send a Question Message to the DTR-5.2 from the HOST to get the current system status. The DTR-5.2 will

10、respond with a status message. 2.3.Event Notice Communication If user change the system status, the DTR-5.2 will notify the HOST by sending the new current status.
