CMX 220 Installation Guide
The Infinity CMX (with or without a built-in modem) is a unique controller. You can connect a terminal to it and program it just as you would an Infinity CX controller, yet it belongs on the Infinet. You can connect four, 16, or 64 Infinet controllers to the CMX, depending on which particular model number you have. From the CMX you can program the Infinet controllers. Every CMX controller has a 2-pin speaker connection where you can connect an audio speaker for use with your modem.
You can also connect to a terminal or printer over a modem from the CMX.
