Computer Control - EAW MX8700 Owner's Manual

5.3.2 Channel Outputs
Each of the eight XLR-M connectors is a transformerless balanced output designed to deliver line level signals.
5.3.3 Power Switch
This switch turns the MX8750 on or off. The outputs are temporarily muted during turn on to protect the
loudspeaker from turn-on transients.
5.3.4 IEC 230 connector
The male IEC connector accepts a standard IEC female connector. Ensure that the MX8700's voltage rat-
ing (see rear panel markings) matches your local mains voltage.
5.3.5 RS232 connector
The DB9-F connector is for connection to a COM port on a computer running EAW's MXWare program.
When two or more MX8750s are linked together, only one processor is connected to the computer. This
connector is wired in parallel with the RS232 connector on the front panel.
5.3.6 Midi In / Midi Out
These are standard 5 pin MIDI connectors that are used to link multiple MX8750s together enabling all to
be controlled from the MXWare program. Up to 16 processors can be linked together. See Section 5.5.
5.3.7 Data Select
This switch selects the status of the MX8750. If it is being used as a single processor or slave unit when
multiple processor are linked together set the switch to Normal. If the processor is being used as the mas-
ter unit when two or more processors are linked together, set this switch to Multi-Unit Master. The multi-
unit master is the processor that will be used to connect to the computer.
NOTE: Only one processor can be a Multi-Unit Master.

Computer Control

NOTE: It is necessary to connect the MX8750 to a computer if you wish to change the configuration or sig-
nal processing parameters. EAW's MXWare program must be installed on your computer in order to com-
municate with the MX8750.
Use either the front or rear panel RS-232 9-pin female connector, not both, for connecting to a computer.
The RS-232 port uses the following protocol: 9600 baud, 8 bits, no parity, 1 stop bit (8N1).
5.4.1 MXWare Program Installation
The MXWare program requires an IBM compatible PC equipped as follows:
Operating System: Windows 98, 2000, ME. NT (Do not use with Windows 95)
I/O: An unused serial port, preferably accessible via a DB9 connector.
To get a copy of the MXWare program you can download it from the EAW web site: http://www.eaw.com/
and go to the "Downloads" page or contact the factory and a copy will be sent to you on a CD-ROM.
If downloaded from the web site, run the "setup.exe" file and follow the instructions in the install program.
An entry will be made in your "Start/Programs" menu and shortcut icon "EAW MXWare" will be put on your
desktop.
Once installed and with the computer connected to the MX8750 open the program by double-clicking on
the EAW MXWare desktop icon or click Start/Programs/EAW MXWare/EAW MXWare.
