Troubleshooting Guide:  Acceleport Xe, Acceleport Xr, Acceleport Xem, Acceleport C/x, Acceleport Epc/x ISA adapters in Windows 2000

1. First, if there is any uncertainty whether you are selecting the correct driver for your adapter, verify the hardware type by checking the serial
    number on the adapter

2. Double-check the driver selected is the correct one for your adapter.
    NOTE: If you have an AccelePort Xem, make sure you select the Digi AccelePort Xem-ISA and not the Digi AccelePort 8e for example.

3. Go to Start, Settings, Control Panel, System, Hardware, Device Manager and verify the resources assigned by the driver. 
    NOTE: The I/O address should correspond with how the dip switches are set on the board.
    A.    Open the device manager and expand the Multi-port serial adapters. The Digi AccelePort that was installed should be displayed.
    B.    Right-click the Digi adapter and select Properties.
    C.    Click on the Resources Tab.  The memory and I/O range settings are displayed here.  You may want to make a note of these values.
    D.    If the settings need to be changed, select the resource you wish to change and click the Change Setting box.  Change the value as 
            necessary.  Click OK. Click OK.  Click Yes. When prompted to restart the computer select Yes.  After rebooting the system, 
           verify that the adapter shows up under Device Manager, Multi-port Serial Adapter and is NOT preceded by a yellow circle with an 
           "!" in it.

4.  If the resource settings do not need to be changed, or if you are not certain whether they need to be changed, continue to the next step.

5.  Check Event Viewer for error messages.  These messages give us clues as to the source of the problem, so read the messages.
     Go to Start, Programs, Administrative Tools (common), and select Event Viewer.  The system log is the log where any driver errors will 
     be recorded.

6.  An error message which states "Wait Confirmation failed - check IO port address settings" indicates that the adapter has not been found.
     There are multiple possibilities for getting this error:
     A.    The I/O port address for the driver does not match the physical position of the dip switches on the adapter.  For example, the dip 
             switches maybe set to 104, while the driver is set to 324.  This needs to be set the same.
     B.    The wrong driver has been selected.  For example, the adapter is an AccelePort Xe, but under Adapters it shows the AccelePort Xr.
     C.    There is another adapter that is using the same I/O port address (this most often occurs at an I/O port range of 100 to about 120).
     D.    If you need to change the resources, go back to step 3.

7.  An error message which states something like "Unable to access ntxem's memory ...." indicates there is a problem with downloading the 
     BIOS image to the adapter's memory.  There are multiple possibilities for getting this error.
     A.    There is an actual memory conflict.  For example, an Adaptec 2940 SCSI adapter is using memory address D0000 to D4FFF, and 
             the Digi driver for the XEM has the memory address of D0000.  If you need to change the resources, go back to step 3.
     B.    The BIOS has a setting to reserve a memory block for an ISA adapter and the user has not reserved the memory address or the user 
             has reserved a memory block that is to small.  The memory block size varies with the adapter:
             Xe requires 8K
             Xr, Xem, C/X and EPC/X require 32K

8.  Take whatever steps necessary to resolve any problems reported in the Event Viewer, whether choosing the correct driver or resolving 
     an I/O or memory address conflict.

9.  At this point, the driver should be installed without any conflicts and the ports available for adding modems, printers, etc.
