Gerry, it's important to be as specific as possible regarding the machine model. Is this a DeVilbiss IntelliPAP2 AutoAdjust? There are several variants:
DV64D IntelliPAP2 AutoAdjust
DV64D-HH IntelliPAP2 AutoAdjust and Heated Humidification System
DV64D-HH-HT IntelliPAP2 AutoAdjust, Heated Humidification System and Heated Tube
DV64D-HH-S IntelliPAP2 AutoAdjust, Heated Humidification System, SmartLink Module, and data card
DV64D-S IntelliPAP2 AutoAdjust, SmartLink Module and data card
An older version DV54 is also out there with nearly identical options.
The DeVillbiss software is called Smartlink, and is described here

Supplier #1 is selling either a USB drive or CD with the "DeVillbiss SmartLink 3.0 software" for $45, and my search showed other vendors at lower prices. I believe the machine data is compatible with Sleepyhead but I have no personal experience with DeVillbiss equipment.
