Extron electronic MTPX Plus Series manual RS-232/RS-422 connection, Ethernet connection

Installation, cont’d

By default, the audio ties follow the video ties. Audio breakaway, which can be activated via the front panel or under serial port or Ethernet control, allows you to select from any one of the audio input sources and route it separately from its corresponding video source. See chapter 3, “Operation”, chapter 4, “Programmer’s Guide”, chapter 5, “Matrix Software”, and chapter 6, “HTML Operation”, for details.

RS-232/RS-422 connection

I	Remote 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 for serial RS-232/RS-422 control (figure 2-9).

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.

NThe switcher can support either the RS-232 or RS-422 serial communication protocol, and can operate at 9600, 19200, 38400, or 115200 baud rates.

See “Selecting the rear panel Remote port protocol and baud rate” on page 3-50, 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 User’s Manual for details.

Ethernet connection

J LAN port

Activity Link

— If desired, for IP control of the matrix switcher, connect the

LED	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
LED	commands from anywhere in the world. You can also control
	the switcher from a PC that is running Extron’s Windows-based
	control program or has downloaded HTML pages from the
	switcher.

Ethernet connection indicators — The Link and Activity 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 Activity LED indicates transmission of data packets on the RJ-45 connector. This LED should flicker as the switcher communicates.
