Make Important Firmware Updates to Your Machine, Even Without Built-In Serial Port
IntelliPAP users must have a serial port available for the firmware upgrade to work; the DeVilbiss firmware and software only support a serial connection.
This adapter connects to any USB port supported by Microsoft Windows and simulates a serial port connection, allowing newer PC–compatible computers without serial ports to connect to a nine–pin serial cable.
