1. Driver Download:
    A.  Make a new directory on the hard drive of the machine with the Digi board in it, (i.e. c:\digi).
    If the system is Intel place the downloaded driver 40000821-01_Z.exe file into this directory. 
    If system is Alpha then use the 4002063X.exe file. 

    B.  Execute the file by double-clicking on the file name (i.e. 4000821-01_Z.exe).  The file will self-extract. 
    A folder will be created for your processor type (i.e., I386 (for Intel) or ALPHA). 

    C.  Go to Start > Settings > Control Panel > Network >Adapter Tab and choose one of the following:
          a.  If this is the first time you have installed the driver, choose Add > Have Disk.
          b.  If you have installed an earlier version of this driver, choose Update. 

    D.  Enter the path to the i386 directory where the driver is stored and then choose OK.
    E.  You will now see a list of Digi drivers.  Select the appropriate driver for your adapter type and follow the prompts. 
Once you have completed the driver installation and rebooted, the Digi board is now ready for use.

1. CD Download:
    A.  From the CD, choose the operating system.
    B.  Choose the Hardware product name.
    C.  Choose the software or driver you wish to install.
    D.  Choose Install Software.
    E.  Follow the prompts.
    F.  Reboot your system if necessary.

TESTING YOUR NEWLY INSTALLED DIGI BOARD:
One of the simplest ways to insure your Digi board is working, is to start with a basic test:
Make sure all other communication programs, (including RAS (Remote Access Service), if opened) are closed.  If your using Windows 
NT 4.0 use the TTY.exe program with the following test. NOTE: Hyperterminal will also work.  The TTY.exe program can be downloaded from our web site.

USING A MODEM TO TEST:
1.  Open the Terminal program.
2.  Select the com port representing the first port on the Digi board (usually COM5). 
3.  Set the Baud rate to 9600 and leave all other settings at the default.  Click on the "ok" button.
4.  Now you'll be at a terminal prompt where you can type ATZ.  You should now see an "OK" response from the modem.

If you can't see what you're typing it may be because your echo is turned off.  Hit "Return" and type ATE1 and now you should see what you're typing and receive an "OK" response from the modem.

If you still don't see what you're typing, check all cabling for loose connections.  When using the Digi "Octa" or "Quad" cable, make sure the end of the cable attached to the Digi card is seated properly.  Try loosening the two thumbscrews and wiggling the cable until you feel a slight click, and then tighten the thumbscrews again (finger tighten only!) and try the test again.

USING THE DIGI LOOPBACK PLUG TO TEST:
If you're not using a modem, use the Digi Loopback plug found in the shipping box and put it on the first port (P1) on the Digi board.

1.  Open the Terminal program. 
2.  Select the com port representing the first port on the Digi board (usually COM5).
3.  Now you'll be at a terminal prompt.  Type any string of characters.  If you can see what your typing, your Digi board is working properly. 


TROUBLESHOOTING TIPS:
1. The most common cause of ISA driver failures is memory conflictions.  Make sure that the memory address (i.e. D0000) is not being used by another device.  This will cause an error message in NT's Event Viewer > System Log stating such a failure. 

Most of today's computers use Pentium proccessors, that are slightly enhanced by using the Shadowing feature in your system's BIOS.  This feature is usually turned on by default and is the reason for most memory contention problems that cause the Digi driver to fail upon load time. Turn this shadowing feature off or disable the memory range that you're trying to load for the Digi driver.


2. The second most common cause of ISA driver failures is an incorrect I/O base address set in the Digi driver.  Make sure that the board's address (set via the dip switches on the board) matches the drivers address setting.  If this setting is incorrect, you will get an error in the Event Viewer 
stating "wait confirmation failed".

3. The most common conflict for PCI driver failure is an IRQ conflict.  Digi's PCI adapters will share IRQs with other PCI devices.  However, sometimes, because another PCI device does not share the IRQ properly, it is recommended that you assign an IRQ to the PCI slot in which the Digi PCI adapter is installed.  SCSI host cards (RAID, Adaptec, etc.) and Network adapters are two examples of types of PCI devices which often will not share the IRQ with other devices.  To do this:
A. Make sure you are running the latest BIOS flash available for your system.
B. Boot into the BIOS and reserve an IRQ for the slot the Digi adapter is installed in.
