Reference Schematic Design Considerations

The following table lists design considerations for the schematics shown in the previous figures.
Table 12. C Series Reference Schematic Design Considerations
Consideration Notes
Current limiter U4 If a current limiter is used, you must re-buffer the sleep signal to the DSUB connector. If a current limiter is not used, you can connect the sleep signal directly to the DSUB connector by removing U15 in the schematic. The buffer prevents the sleep signal from being driven to the C Series module in an overcurrent condition.
