Installation of FX Cards

IMPORTANT: Shut off power to the Digital 8•Bus’ Remote CPU before installing or removing cards. Also, install your FX cards in order. For example, put your first FX card in the slot marked “A,” your second FX card in slot “B,” etc.

1. Loosen the four spring-loaded screws on the blank cover plate to the FX card slot you want to fill.

2. With your finger in the hole on the FX card (and the components on the circuit board facing to the left), push the card firmly into the white connector slots so it fits snugly. Do not touch any of the circuit board components or solder joints.

3. Replace the cover plate and tighten the screws securely using a slotted screwdriver. DO NOT OVERTIGHTEN THE SCREWS, or you run the risk of stripping the threads in the D8B.
