7.4.2 Digital Outputs
The high-current digital outputs are either sinking or sourcing, depending on the model of
the Digital I/O Card. Table 12 provides the pinout configuration for the output points.

Figure 29. Digital I/O Card Power Distribution
When designing your interface with the Smart Star system, you need to establish whether
you will use the +V_USER/+RAW supply on the backplane or your own independent K
supply to drive the high-current outputs. The selection of this FPWR power supply is
implemented via a 0 ? surface-mount resistor on header JP1 (sinking outputs) or header
JP3 (sourcing outputs) as shown in Figure 30. The factory default is to use
+V_USER/+RAW , but Digital I/O Cards are available in quantity with the FPWR power
supply jumpered to your own independent K supply.
