DigitalMedia™ Connectors: DM-CONN-20
Description
DM-CONN-20 is a package of 20 RJ-45 shielded connectors
designed for use in terminating Crestron
®
DigitalMedia Cable
(DM-CBL). DigitalMedia connectors come in two parts and
are used to terminate the blue Shielded Twisted Pair (STP)
cable (sectional view shown to the right) that plugs into the
D
port of a DigitalMedia device.
Proper cable termination will ensure that the cable lengths for
the terminated CAT5e and terminated STP cables are similar.
The only tools required for assembly are a wire stripper, razor
knife and side cuts (or edge nippers).
Use the following procedure to assemble the connectors with
STP cable. Use caution to avoid nicking or cutting the wires or
insulation. Pin assignments are listed in the table to the right.
1.
Strip 6 inches (153 mm) of the DigitalMedia Cable to
expose the three inner cables.
2.
Strip the blue outer jacket of the STP cable 1 3/4 inch
(45 mm) from end. Gather and twist the braid. Refer to
“Strip Jacket and Trim Shield” to the right.
3.
Trim foil shield to 1/2 inch (13 mm) and fold back against
the outer jacket of the cable. Refer to “Strip Jacket and
Trim Shield” and “Fold Foil and Cut Spline” to the right.
4.
Remove the white inner jacket and separate the twisted
pairs to expose the spline. Cut the spline so that it is near
flush with the outer jacket of the STP cable. Return
twisted pairs to original position. Refer to “Fold Foil and
Cut Spline” to the right.
5.
Fold foil shield back to original position over wire pairs.
Neatly wrap twisted braid around foil shield. Only silver
side of foil shield is conductive. Refer to “Wrap Braid
around Shield” to the right.
NOTE:
Braid should wind neatly around foil shield. Loose
braid may cause shorts or difficulty completing assembly of
connector.
NOTE
: Do not allow the twisted pairs to untwist for more than
1/2 inch (13 mm).

6.
Arrange brown and green wire pairs for T568B
termination (shown on the attached tag). Insert the brown
and green wire pairs into the holes in the connector.
Refer to “Insert Wires in Holes” to the right. Pull the
excess wire through the holes until the wrapped braid is
near flush to the insertion point of the holes.
7.
Arrange the blue and orange wire pairs for T568B
termination (shown on the attached tag). Seat the blue
and orange pairs in the wire channels on the top of the
connector. Refer to “Attach Plastic Clamp” to the right.
8.
Snap the attached plastic clamp to secure the wire. Refer
to “Attach Plastic Clamp” to the right.
9.
Trim the blue and orange pairs with the side cuts so that
they are flush with the end of the wire channels. Trim the
brown and green pairs so that the ends are flush with the
holes on the connector. Refer to “Trim Wires” to the right.
10. Align and attach the other half of the connector. To
complete assembly, press firmly until you hear a click.
Refer to “Complete Assembly” to the right.
