The 1771ĆIFF/A module is slotted at two places on the rear edge of the circuit board. These
slots mate with plastic keying bands which mount on the backplane connector.
Position the keying bands in the backplane connector to correspond to the key slots.
The keying bands can be repositioned if subsequent system design and
rewiring make insertion of a different type of module necessary.
