Control connections
The MKP has two RS-232 ports (a Host port [ 4 ] and a Switch
port [ 5 ]) and an LAN (Ethernet) port ( 1 ). The following
paragraphs describe different possible ways of connecting the
MKP to a switcher via RS-232 or Ethernet.
RS-232 connection
An MKP control panel can be directly cross-connected to any
Extron matrix switcher through the switcher’s switch RS-232
port (see figure 2-16, 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).
In the configuration shown in figure 2-11, additional
(secondary) MKPs are connected to the primary MKP via the
primary MKP’s Ethernet port.

Figure 2-11 — MKP connection using the RS-232 port
3 Remote Keypad port — If desired, plug the optional
MKP 10 MAAP remote keypad into this 10-pin connector, using
the cable included with the MKP 10 MAAP.
This connector is always used on the standard keypad on
an MKP 3000 L.
4 Host RS-232 port — If desired, connect a host computer or
control system to this 3-pole, 3.5 mm, RS-232 connector
(figure 2-10).

5 Switch RS-232 port — If desired, connect a cable between this
3-pole, 3.5 mm, RS-232 connector and a matrix switcher
(figure 2-10).
6 MAAP Opening (MKP 3000 MAAP) — The MKP 3000 MAAP
has a space that allows the installation of up to four optional
mini architectural adapter plates (MAAPs). This space is
typically filled by an optional four space MKP 10 MAAP
keypad, but a variety of other adapter plates are also available.
Blank plates (two single-space and one double-space plate) are
included with the MKP to cover unused spaces. The
MKP 10 MAAP or other MAAP(s) must be ordered separately.
They also should be attached to the faceplate and cabled before
the MKP is installed in the wall or furniture. See “Mounting the
MKP 10 MAAP,” later in this chapter.
7 Keypad board (MKP 3000 L) — The 12-button keypad that is
built into the MKP 3000 L rear panel is connected to this board.
