Digital inputs, digital outputs, external voltage, and external reset are routed via the CON2 con-
nector. Interfacing to the CompactPCI bus is accomplished via the CON1 connector. Test and
program development is supported by the CON3 connector.

External supply for each output cluster:

The connection for the external supply (+24V DC [9.5V to 35V] for each output cluster) is real-
ized by reserved/defined pins within each output cluster at the front panel connector CON2.

External reset for each output cluster:

The digital outputs will be brought to zero output level on power-up. In addition to the reset by
software, the reset lines (one per each output cluster) are routed to the front panel.

Digital Input and Output Interface

The digital input and output interface is routed through the CON2 connector. The following fig-
ure and table indicate the pin layout and pinout of this connector.

Figure 2-2: Pin Layout of the Digital Input and Output Interface Connector CON2

Note ...

In addition to supplying the current for the logic parts of the power switches
which are linked to the digital outputs, the external voltage supplies also have to
supply the current for the 8 digital output loads per cluster.
