===================================================== INSTALLATION OF THE WINDOWS NT 4.0 and NT 3.51 DRIVER ===================================================== ************************************************** BEFORE INSTALLING THE NEW DRIVER ************************************************** Before you install the new driver, make sure that you remove any drivers currently installed and reboot. To remove the driver go to Control Panel/Network and remove the Digi board driver from the Adapters Tab. Failure to do so may cause complications. ************************************************** INSTALLING THE NEW DRIVER ************************************************** 1 - 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 40000821-01_Y.exe file into this directory. If system is Alpha then use the 4002063X.exe file. 2 - Execute the file by typing its name in a DOS window or double-clicking on the file icon. The file will self-extract. A folder will be created for your processor type (i.e., I386 (for Intel) or ALPHA). 3 - Open Control Panel/Network/Adapter Tab and select Add. When you see the list of adapters, scroll to the bottom of the list and select `Other', (For Windows NT 4.0 you would choose the `Adapter' tab and click on the `Have Disk' button). Then enter the path to the I386 directory (or appropriate processor directory) that the file made when it extracted, (i.e. c:\digi\I386). 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. ************************************************** 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 program with the following test. The tty program, called "nt_tty.exe", can be downloaded from our BBS or FTP server, (refer to the end of this document). USING A MODEM TO TEST 1 - Open the "Terminal" program (found in the "Accessories" group) and choose the "Settings" pull-down, then "Communications". 2 - Select the com port representing the first port on the Digi board(usually com3).Remember that "Terminal" can only access com1-com9. 3 - Set the Baud rate to 9600 and click on the "ok" button. 4 - Now you'll be at a terminal prompt where you can type "ATZ" ,(without the quotes). 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" (without quotes) 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,(finger tighten only!). 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 (found in the "Accessories" group) and choose the "Settings" pull-down, then "Communications". 2 - Select the com port representing the first port on the Digi board(usually com3).Remember that "Terminal" can only access com1-com9. 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 ************************************************** The most common cause of all driver failures is memory conflictions. Make sure that the memory address (eg D0000) is not being used by another device. This will cause an error message in NT's Event Viewer 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 the Digi driver at.(If your not sure how to do this, contact your computer manufacturer or BIOS manufacturer for information on this procedure) The second most common cause of all driver failures is an incorrect i/o base address set in the Digi driver. Make sure that the board's address matches the drivers address setting. If this setting is incorrect, you will get an error in the Event Viewer stating "wait confirmation failed". ************************************************** WHERE CAN YOU GET THE DRIVER? ************************************************** Internet(FTP)..................ftp://ftp.dgii.com Digi Tech Support..............(612)912-3456 **************************************************
