The two composite outputs are typically used for Multizone distribution through a

McIntosh A/V Control Center and/or A/V Multizone Control System.

RS-232 Connections

External disc changers are controlled via two-way serial protocols using RS-232 serial

cables. You should use COM ports 1, 2, and 3 for each external disc changer.

COM port 4 is to be used for connecting an external modem or to interface with a third

party control system such as AMX or Crestron.

Note: You should use the Ethernet control system for controlling the MS300 from a third

party control system whenever possible. Using the Ethernet control system frees up COM

port 4 for other purposes, allows much longer distances between the MS300 and the

control system, and provides a much faster path for data transfer.

External Modem Connections

Use of an external modem for connecting to the Gracenote™ disc lookup services should

only be used if a broadband connection is not available. Any external modem, which

supports the standard AT Hayes command set and supports a serial connection (RS-232),

will work. USB modems will not work. Contact McIntosh Technical Support for more

information on compatible modem options.

IR Connection

The IR Port uses a 1/8 inch stereo mini phone plug and allows the

connection of other brands IR Sensors to the MS300. The IR input jack

provides 12V power.

Data Port Connection

The MS300’s Data Port Input receives Remote Control Signals. Use a

1/8 inch stereo mini phone plug to connect to the Data Port Outputs on

McIntosh A/V Control Units.

Power Control Connection

The MS300’s Power Control Input accepts a 5 volt (12 volt compliant)

Power On/Off signal. Use a 1/8 inch stereo mini phone plug to connect to

the Power Control Output on other McIntosh Components.
