Control connections

The MKP has two RS-232 ports — a Host port (
port ( ) — and an Ethernet (LAN) port (
3
An MKP control panel can be directly cross-connected to any
Extron matrix switcher through the switcher's RS-232 port (see
figure 2-12, later in this chapter, for pin assignments for the
RS-232 cable). 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 (the primary MKP). The additional
(secondary) MKPs are connected to the primary MKP via the
primary MKP's Ethernet port. Figure 2-8 shows an example of
this type of configuration.

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 TP (network) cable that is wired as a
crossover cable (see "TP cable termination," later in this chapter,
to properly wire the cable).

Matrix Switcher
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-through) cables.

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:
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).
Cut off the foil shield and discard it.
3.
4. Strip ¼" ( 0.6 cm) of insulation from any three of the four
wires (not including the drain [unshielded] wire).
5. Twist the strands of each wire, insert the strands into the
direct insertion connector, and tighten the captive screws.
