AUTOMATION

Fig 6

Any AX4752 parameter is controllable using the serial RS232 interface. The RS232 protocol is outlined

in the following section, and encompasses both the amplifier and connected keypads. The interface is

bi-directional, allowing the amplifier and network to be monitored.

The RS232 port connection must be made using a ‘Null Modem’ cable, where pin’s 2 & 3 are swapped

at one connector.

Fig 6 shows a typical touch panel controller providing the user interface to an AX4752. The controller

has it’s own operating system that is programmed to handle the Axium 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 terminals. Each zone on the AX4752 may be set to a specific input (utility) and at

specific volumes (depends on room & application). When the contact closure is opened the AX4752

returns to its previous states. The ‘Page Preset’ is useful for telephone paging, door & gate phone

paging, or doorbell applications.

Axium also offers a six-channel relay driver – REL6 – which may be encoded for up to 16 Zones of IR

control. Typical REL6 applications are the control of curtains, screens, fan / fan speed, lights or

other simple On / Off applications that require IR remote control.
