Installing the
Interface Module
Important: Make sure you carefully align the pins and holes before you press the connector header into
the processor. If you improperly align them, you will bend the connector header pins when
you press them together. Do not use excessive force on the connector header when seating it
into the processor. You do not need to key the connector.
4. Use
the captive screws to connect the interface module to the processor .
