1. Specifications

RS232 Port

The RS232 Asynchronous serial port provides data acquisition and control of Axium networks by

a Home Automation System, or personal computer. Only one RS232 connection is necessary

when interfacing with an Axium network.

The lead must be 'Null modem' : 9 pin female 'D' connectors at both ends (pin connections 2 and

3 swapped at one end)

See appendix1: RS232 protocol for more information.

PRESET Utility

A voltage free contact closure forces all Axium amplifiers (Zones) into their PRESET mode.

Open circuiting the terminals restores the amplifiers to their previous states.

10 way Terminal Block

Amp-ON A

Amp-On B

Amp-On C

IEC Fused AC Power Socket

An IEC AC power socket provides the possibility of international power connectivity.

The operating voltage may be changed internally to 110VAC.

Fuse = 1.6Amp Slow blow, size =20mm. Replace only with same rated fuse!

Speaker Outputs

Speaker A, B, C & D outputs are BANANA sockets.

If both A & B are used then the maximum load on each output is 8 ohms. (4 ohms min/amp)

If both C & D are used then the maximum load on each output is 8 ohms. (4 ohms min/amp)

The BLACK outputs are all common.

The RED outputs must never be connected together. It is not possible to operate the amplifiers in

parallel or "Bridge Tied Load".

0V connection to Axium controllers and accessories.

Infra-Red input from Axium controllers.

Self-resetting Poly fused +12Vdc power supply for Axium controllers and

accessories. The maximum number of controllers is four.

If this is exceeded it is likely that the internal fuse may trigger open circuit.

The logical 'OR' of the Amp-On outputs. If any speaker output is ON, then Σ is

On (12V). This is used to switch power sockets for connecting AC power to

Audio source components. i.e. CD players, Tuners etc.

If Speaker A (Zone 1) is ON then output will be +12V. Current limited (25mA)

If Speaker B (Zone 1) is ON then output will be +12V. Current limited (25mA)

If Speaker C (Zone 2) is ON then output will be +12V. Current limited (25mA)

If Speaker D (Zone 2) is ON then output will be +12V. Current limited (25mA)
