Introduction
Kramer DGKat™ twisted pair cable is ideally suited to extend digital video signals with twisted pair transmittersand receivers. In Pro AV applications it impossible to predict the environment so it is best to always use
shielded twisted pair cables. It is important to always use Kramer RJ-45 connectors with Kramer twisted
pair cable as they are engineered to work with Kramer DGKat cable.
White there may be different ways to terminate twisted pair cables, Kramer has found the following method
to be considered a best practice and it is a requirement for use with certain Kramer products in order forthem to function to their maximum specifications.

Tools Required» Razor knife» Wire cutters» Pliers» Standard RJ-45 crimp tool» Soldering Iron» SolderProcedure
Step 1: Remove approximately 2.5” of the jacket using the razor knife exposing the 4 shielded pairs anddrain wire. Fold the drain wire over onto the cable for future use.

Step 3: Un-twist each pair and straighten the individual conductors. Be sure to keep each pair together so
it can be identified.

Step 4: Using the standard wiring scheme shown below (T568B), insert conductors into plastic loader pieceof the RJ45 connector. The plastic loader is necessary because the thickness of the Cat6 cable does not allow
it to sit flat in a RJ-45 like in normal CAT5. Notice how the loader staggers the cables in the pictures below.

Step 5: Slide the plastic loader down the cable as close to the base as possible. Keep pressure on the top
and bottom of the loader so cables stay in place while sliding down.

Step 6: Using the wire cutters, cut all conductors leaving approximately ½ an inch remaining.

Step 7: With the orange pair on the left and the clip of the RJ45 connector facing down, insert the cable
into the RJ45 connector, pushing the cable all the way in until the exposed pairs contact the back of theconnector.

Step 8: Using the standard crimp tool, crimp the RJ45 connector.

Step 9: Flip the drain wire up onto the RJ45 connector. Clamp the strain relief down on the jacket of theDGKat cable using pliers.

Step 10: Solder the drain wire to the metal casing of the RJ45 connector and cut off the excess using thewire cutters.
