Extron electronic MCP 1000 Damage may occur to circuits if cable wire, Trimming the cable jacket

Installation, cont’d

Cables must be made with the appropriate connector on each end. Regardless of the connector that is being used, the wiring must be one-to-one (for example, red-to-red and A-to-A).

CAUTION	Damage may occur to circuits if cable wire
	assignments are not the same on both ends.

The total cable length for connecting MCP 1000s and MKP 1000s to a matrix system must not exceed 1000 feet (305 meters).

To attach connectors to the cables,

1.	Trim approximately 1.5 inches of the cable jacket to expose
	the four insulated wires and a bare drain (ground) wire
	(silver colored).

Trimming the cable jacket

2.	Cut off and discard the foil shield.
3.	Strip 0.25 inches of insulation from each of the four wires.
4.	Twist the strands of the black
	wire, insert it into the opening
	that corresponds to pin E, and
	tighten its captive screw. (See the
	illustration at right.)

5.	Twist the strand of the drain	1
	wire, insert it into position D, and
	tighten its captive screw.	3.5 mm captive
6.	Connect the remaining wires in	screw connector on
		MCP 1000
	the same way (for this example,
	white, violet, and red).

7. Choose the appropriate captive screw connector and repeat steps 1 through 6 for each cable end.

Both types of captive screw connectors use a “moving cage” to damp the wires, without the need for soldering.

Extron’s Plenum Comm-Link cable

Extron’s Plenum Comm-Link cable was designed for use with the MCP 1000 and MKP 1000. If another cable will be used, it must meet the following specifications:

A (red) — 18 AWG

B (violet or blue) — 22 AWG (grouped and shielded)

C (white) — 22 AWG

D (drain) — 24 AWG

E (black) — 18 AWG

See appendix A, "Specifications, Part Numbers, and

Accessories," for a list of Extron cable part numbers.
