Any MZA-4.7 parameter is controllable using the serial RS232 interface. The RS232 protocol is outlined in the follow- ing section, and encompasses both the ampliﬁer and connected keypads. The interface is bidirectional, allowing the ampliﬁer and network to be monitored.

The interconnecting cable must be straight: 9 pin ‘D’ connectors.

Fig 6 shows a typical touch panel controller providing the user interface to an MZA-4.7. The controller has its own operating system that is programmed to handle the RS232 protocol. An automation system is not restricted to touch panels, it may be an extension of a home lighting, security, building management, or other specialized home automation system.

The “Page Preset” is a special preset that is invoked whenever there is a contact closure across the “PG” and 0V termi- nals. Each zone on the MZA-4.7 may be set to a speciﬁc input (utility) and at speciﬁc volumes (depends on room and application). When the contact closure is opened the MZA-4.7 returns to its previous states. The “Page Preset” is useful for telephone paging, door and gate phone paging, or doorbell applications.

Note: The S8 input is summed with the internal doorbell generator.
