Removing a Jumper Head
An interface is AC coupled if there is no jumper head on the associated jumper
pins. If you want to change an interface coupling from DC to AC, remove the
jumper head as follows:
1.
Locate the jumper pins you want to configure ( Figure 1-2 on page 1-4 ).
2.
Grasp the jumper head with your fingers, then pull it up (Figure 1-4) .
