2-7 Fiber Matrix 6400 Switcher • Installation
RJ-45 connector wiring
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 2-4).
• Crossover cable — Direct connection between the computer and the Fiber
Matrix switcher
• Patch (straight) cable — Connection of the Fiber Matrix switcher to an
Ethernet LAN
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable. A cable wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

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 2-5).

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/
configuration software.
N The 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 3-27,
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.
