RS-232/RS-422

h RS-232/RS-422 connector — Connect a host device, such as a computer, touch panel control, or RS-232 capable PDA to the switcher via this 9-pin D connector on BME 0 only for serial RS-232/RS-422 control (figure 2-10).

See chapter 4, SIS Programming and Control, 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.

NThe 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.

Ethernet

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.

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 on BME 0 only. 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.

Activity Link

LED LED

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.
