To Tap
Pull the removable frame out to the switch-setting position before
connecting to the tap. This is the only way to be sure that the dropline
will have enough slack in the switch-setting position. (Remember the
3-inch minimum bend radius.) Plug the right-angle plug of the dropline
into the jack labeled DATA HWY II PORT on the 1779-KFM interface.
Then, plug the other end of the dropline into the jack on the front of the
tap (Figure 4.9).
