Extron electronic MKP 2000 user manual Control connections, RS-232 cable termination

Installation, cont’d

Control connections

The MKP has two RS-232 ports; a Host port ( 1 ) and a Switcher port ( 2 ); and an Ethernet (LAN) port ( 3 ).

Any number of control panels can be connected, as part of a network, to any Ethernet-enabled matrix switcher via the switcher’s Ethernet port (figure 2-10). All TP cables in this example are wired as patch (straight) cables.

An MKP control panel can be directly connected to any Extron matrix switcher through the switcher’s RS-232 port (figure 2-8). A control system or host computer can be connected via the MKP’s host RS-232 port. Additional MKPs can be connected to the matrix switcher through the MKP that is RS-232 connected to the switcher (the primary MKP). The additional (secondary) MKPs are connected to the primary MKP via the primary MKP’s Ethernet port.

RS-232 cable termination

Each MKP control panel has two RS-232 ports that are connected using 3.5 mm, 3-pole direct insertion connectors. Wire the connectors as follows:

Figure 2-8 — MKP connection using the RS-232 port

An MKP control panel can be directly connected to any Ethernet-enabled matrix switcher via the switcher’s Ethernet port (figure 2-9) using a network (TP) cable that is wired as a crossover cable (see TP cable termination to properly wire the cable).

Figure 2-9 — Direct MKP connection using the LAN port

		The total cable length between an MKP control panel
		and a matrix switcher should not exceed 100 feet (30 m).
1.	Choose a cable such as Extron’s Comm-Link cable. The
	wire specifications for Comm-Link cable are on page A-6.
	Colors may vary from this example.
2.	Trim approximately 1.5" (3.8 cm) of the cable jacket to
	expose the four insulated wires and a bare drain wire
	(silver-colored).
3.	Cut off the foil shield and discard it.
4.	Strip 1/4" ( 0.6 cm) of insulation from three of the four
	wires.
5.	Twist the strands of each wire, insert them into the direct
	insertion connector, and tighten the captive screws.
