Please read our Compatibility List for Windows for a list of serial devices that have been tested with the Keyspan USB Serial Adapter. Keyspan USB Serial Adapter Port Keyspan USB Serial Adapter Serial Port The DB9 port on the Keyspan Adapter is seen as a COM port by Windows. The Keyspan COM port is interfaced via the "Win32 Communications API" and is then available to any program that accesses COM ports via this API. By default, the COM port number assigned to the Keyspan adapter is the first unassigned (available) COM port number in the Windows registry. For example, if COM1 and COM2 have already been assigned or set aside by any software or hardware, the Keyspan adapter will take the next COM port (COM3). This COM port number can then be accessed via your serial device's software (ie Palm's HotSync Manager, Wacom tablet control panel, etc.) Note: You can connect more than one Keyspan USB Serial Adapter to your USB equipped Windows computer. The DB9 ports on subsequent adapters will have a different COM port numbers. Rev 03jul13 This User Manual applies to the Keyspan USB Serial Adapter Software for Windows. Page 3
