9. Make a copy of the reverse side of this worksheet for each of your chassis, and use it to record
your responses to items 2 through 8.
10. Indicate the addressing mode for each chassis. Use the table below to guide your selection.
If the densest I/O module in the chassis is: And you want to: Then choose:
