Figure 2-20 — RS-232/RS-422 connector
See chapter 4, “Programmer’s Guide”, for definitions of the SIS commands
(serial commands to control the switcher via this connector) and chapter 5,
“Matrix Software” for details on how to install and use the control software.
N The switcher can support either the RS-232 or RS-422 serial communication
protocol, and operate at 9600, 19200, 38400, or 115200 baud rates.
See “Selecting the rear panel Remote port protocol and baud rate” in chapter 3,
“Operation”, to configure the RS-232/RS-422 port from the front panel.
If desired, connect an MKP 2000 or MKP 3000 remote control panel to the
switcher’s RS-232/RS-422 connector. Refer to the “ MKP 2000 Remote Control
Panel User’s Manual ” or the “ MKP 3000 Remote Control Panel User’s Manual” for
details.
Ethernet
i
Ethernet port — If desired, for IP control of the system, connect the matrix
switcher to a PC or to an Ethernet LAN, via this RJ-45 connector.
You can use a PC to control the networked switcher with SIS
commands from anywhere in the world. You can also control
the switcher from a PC that is either running Extron’s windows-
based control program or that has downloaded HTML pages
from the switcher.
Ethernet connection indicators — The Link and Act LEDs
indicate the status of the Ethernet connection. The Link LED
indicates that the switcher is properly connected to an Ethernet
LAN. This LED should light steadily. The Act LED indicates
transmission of data packets on the RJ-45 connector. This LED
should flicker as the switcher communicates.
