The RS232 data port provides a place to connect a PC computer for system
configuration using the included SmartMixer Software. (Refer to the Software
Section for installing/using the software.) Alternatively, the data port may be
used to connect to an external control system such as Crestron® or AMX®
running "open disclosure communications protocol". Refer to information from
control system manufacturer regarding using this feature.
In a system with multiple linked AT-MX381's, connect the PC or control system
to the first (Master) unit in the chain. This will allow access to all of the linked
units for configuration and control programming.
