RS-232/RS-422 Link
The rear panel RS-232/RS-422 connectors (figure 4-1) of the matrix switcher BME 0
can be connected to the serial port output of a host device such as a computer
running the HyperTerminal utility or a control system. This connection makes
Simple Instruction Set (SIS) control of the switcher possible from the computer or
host via the RS-232/RS-422 link.
Figure 4-1 — RS-232/RS-422 connector pin arrangement
The default communications rate is 9600 baud. Baud rates of 19200, 38400, and
115200 are also available, see Changing the serial port baud rate, in chapter 6, Upgrades
and Maintenance. The protocol is 8-bit, 1 stop bit, no parity, and no flow control.
Ethernet Link
The rear panel Ethernet connector (figure 4-2) on the matrix switcher BME 0 can be
connected to the an Ethernet LAN or WAN. This connection makes SIS control of
the switcher possible using a computer connected to the same LAN or WAN.
Ethernet connection
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 4-2).

Default IP address
To access the Matrix 12800 switcher via the Ethernet port, you will need the Extron
IP address. If the address has been changed to an address comprised of words and
characters, the actual numeric IP address can be determined using the Ping utility
(see appendix A, Ethernet Connection, for more details). If the address has not been
changed, the factory-specified default is 192.168.254.254.

The Matrix 12800 Switchers are factory configured for RS-232 control. To use
the switcher under RS-422 control, you must change an internal DIP switch.
See Swapping the serial port protocol (RS-232/RS-422) in chapter 6,
Upgrades and Maintenance, for details.
Crossover cable — Direct connection between the switcher and a controlling
computer.
Patch (straight) cable — Connection of the switcher to an Ethernet LAN.
If the local system administrators have not changed the value, the factory-
specified default, 192.168.254.254, is the correct value for this field.
