Installation of I/O Cards

IMPORTANT: Shut off power to the Digital 8•Bus’ Remote CPU before installing or removing cards.

1. Using a #2 Philips screwdriver, unscrew the blank cover plate corresponding to the I/O card slot you want to fill.

2.Holding the I/O card so that the components on the green circuit board face to the left (see diagram), line up the card so the top and bottom edges fit into the white guide slots. Do not touch any of the circuit board components or solder joints.

3.Be sure to push the card in all the way—until the front of the I/O card is flush with the back panel of the D8B. This may require a good, solid push, so don’t be shy.

4.Tighten the spring-loaded screws on the

I/O card securely using a slotted screwdriver. DO NOT OVERTIGHTEN THE SCREWS, or you run the risk of stripping the threads in the D8B.
