RS-232 connectors (master)
a 
Power connector — Plug the provided power cord into this 
connector to connect the MCP to a 100-250 VAC, 50/60 Hz 
power source. 
b
  Switcher — Use this 9-pin connector for communication 
between the MCP 1000 and a comm port on the switcher that 
will be controlled by the MCP 1000.
c
  Host — Use this 9-pin connector for communication between 
the MCP 1000 and a comm port on the RS-232 controlling device 
or a computer with Extron’s control software for Windows 
installed.
CAUTION
  Do not use delay or pause characters (commands 
that delay execution of the next SIS command) in 
RS-232 commands. Use contiguous SIS characters.
The RS-232 connector uses the following pin assignments:

The illustration on the next page shows a host controller and a 
switcher connected to the RS-232 ports on the MCP 1000.

Comm-link connectors (master or slave)
d
 and 
e
 Comm-link panel connectors — Connect a matrix 
switcher or another (master or slave) MCP to these 5-pole, 5 mm 
male connectors. The MCP 1000 includes two female connectors 
for making cables.
Although comm-link connections can be used in a master 
application, the typical application is a large matrix system, such 
as a Matrix 6400. This can include multiple MCP 1000 units, 
as well as MKP 1000 units, intermixed. See the application 
examples illustrated in chapter 3, "Operations."
Making cables
Choose a cable such as AMX/Panja’s Axlink, Crestron’s Cresnet, 
or Extron’s Plenum Comm-Link cable. The wire specifi cations 
for comm-link cable are on page 2-5. After running the cables, 
follow the procedure below to install the connectors.
The appropriate connectors are shipped with each device: 
MCP 1000 — Use 5 mm connectors (Extron part number 
10-163-13).
MKP 1000 — Use 3.5 mm connectors (Extron part number 
10-319-10).
Matrix 3200/6400 master BME — Use 5 mm connectors (Extron 
part number 10-163-13).
CAUTION
  Do not connect both a Matrix 3200/6400 BME 
and an MCP 1000M (master) unit on the same 
comm-link connection. Also, do not connect more 
than one master on the same comm-link connection.  
Both of theses units supply voltage to the comm-
link ports on pins A and B. Connect these pins 
to only one power source. This does not apply to 
MCP 1000S (slave) units.
