By default, the audio ties follow the video ties. Audio breakaway, which
can be activated via the front panel or under serial port 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”, and chapter 5, “Matrix Software”, for details.

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 can operate at 9600, 19200, 38400, or 115200 baud rates.
See “Selecting the rear panel Remote port protocol and baud rate” on page 3-42,
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.
Reset button
i
Reset button — The Reset button initiates two levels of reset to the
RESET
matrix switcher (see “Rear Panel Operations” in chapter 3, “Operation”,
for details):
• Rear panel (mode 5) system reset — Press and hold the Reset button
while the switcher is running until the Reset LED blinks three times
(approximately 9 seconds), then release the button and push it again.
This reset clears all ties and presets and resets all audio gains to 0 dB.
• Hard reset — Press and hold the Reset button while powering up the
switcher to perform all of the mode 5 reset functions and restore the
switcher to the default factory conditions.
N Hard reset does not clear the current configuration.

AC power connector — Plug a standard IEC power cord into this connector to
connect the switcher to a 100 VAC to 240 VAC, 50 or 60 Hz power source.
W The power connector is wired double pole with neutral fusing.
