Rear Panel AUX I/O Connector
A.4.1
Pin Identification
The AUX I/O connector exposes a number of internal electrical signals. For
convenience, a number of logic inputs and outputs are included, thereby negating the
need for extra PC based IO hardware. Using the APT support software, these user
programmable logic lines can be deployed in applications requiring control of external
devices such a relays, light sources and other auxilliary equipment.
The pin functions are detailed in in Fig. A.7 .

external equipment that is not galvanically isolated from the mains or is
connected to a voltage higher than the limits specified in Section A.4.2.
to Section A.4.4. In addition to the damage that may occur to the
controller there is a risk of serious injury and fire hazard.
