voltage. However, the ports can also be triggered directly by a logic signal as long as the logic 'low'

goes below +0.5V.
The action is: X = Mute when connected to Ground (0v), Y = Sleep when connected to Ground (0v).

Fault Relay A

Three connections are available via a Phoenix connector for this relay. The schematic representation
printed on the rear panel shows the 'idle' state of the relay (when the amplifier is not switched on).
When the amplifier is switched on, the relay will normally energise. When a Fault incident occurs, the
relay will be de-energised. This will allow either a Fault Incident or a loss of power to be seen as an
'Incident'.

AUX Port B

The AUX B connector has five logic inputs. The default operation is to recall one of the Snapshots 1 to
5 by applying a Ground (0v) to one of these pins, either momentarily or permanently.
NOTE: That if this port is being driven by a Ground (0v) on any input, this will override a snapshot
recall over the third party Tipi interface or in System Engineer.
Also see Snapshots.

Check Relay B

Three connections are available via the Phoenix connector for this relay. The schematic
representation printed on the rear panel shows the 'idle' state of the relay (when the amplifier is not
switched on). When the amplifier is switched on, the relay will normally energise. When a Check
incident occurs, the relay will be de-energised. This will allow either a Check Incident or a loss of
power to be seen as an 'Incident'.

AUX Port C

The AUX C connector carries:
• 5v, Gnd: This power output may be used for energising external indicators etc from either the
Fault relay or Check relay for example. This output is not capable of supplying more than
100mA of current.
• Hb: The Heartbeat output. This outputs a 1Hz square wave all the time the unit is operating
correctly.

RS232/ RS485

Serial communications Connectors: The device may be controlled via this 'third party interface' using
either RS232 or RS485 protocol at a rate of 38.4k Baud. Only one of these may be used at a time.
Please refer to the "Tipi Interface Specification" document for details on how to use it.
