Note The eight pins of the adapter are marked and have a one-t o-one correlation to the eight lines on the RJ-45
connector.

turn off the power. However, you should wire-wrap the cable conductors to the applicable pins on the
adapter before you plug the adapter into the card .
Complete the following steps to connect the external clock using the wire-wrap adapter:
