Windows NT V3.51
For Windows NT applications, it is important to note that WaveView can only be run on Windows NT 4.0,
or higher. Windows NT 3.51 is not fully supported.
Windows 95/98/2000 Problems
This section only applies to Windows 95/98/2000 installations.
Resource Settings
If the WavePort fails to communicate or has problems transferring data, there may be a resource conflict
with other devices within the system. Take the following steps if this appears to be the case.
Parallel Port Setup
If WavePort fails to communicate or has problems transferring data there may be a problem with the way
the parallel port is configured. If this appears to be the case take the following steps:
1 Ensure that any hardware settings on the parallel port are configured properly. If unsure of proper
configuration, refer to the parallel port manufacturer's documentation. If this fails to solve the problem,
proceed to the next step until the problem is resolved.
2 Click the Windows desktop Start button; select the Settings menu item; then, select the Control Panel
menu item.
3 Double-click the System icon.
4 Click the Device Manager tab.
5 If the small box to the far left of the "Ports (COM & LPT)" entry contains a "+", click once on the "+"
to show all your communication and line printer ports.
6 In the Configuration utility, click once to highlight the line containing the LPT port you chose to use
with WavePort.
7 Click the Properties button.
8 The Device Status section should contain the message “This device is working properly.” If the
message is not present, either the wrong I/O address is selected, or the hardware is missing or broken.
9 Click the Resources tab.
10 The Resource Settings section should contain entries for “Input/Output Range” and “Interrupt Request”
with “Settings” from the table below that correspond to the LPT port chosen for WavePort.
Note: A “Direct Memory Access” entry may also exist for EPP or ECP printer ports.
Printer Port Input/Output Range Interrupt Request
LPT1
0378-037B (or 037F) 7
LPT2 0278-027B (or 027F) 5
LPT3 03BC-03BF 7 (shares with LPT1)
If the settings do not correspond to those in the above table, or if there is no "Interrupt Request" entry,
follow these steps 10a through 10b before moving on to step 11.
10a.Click on the check mark in the small box to the left of "Use automatic settings".
10b. Click on the now active drop-down combo-box to the right of "Setting based on:"
10c. Click on different "Basic configuration" choices (use the up-down slide bar to the right if needed)
until the resource settings match those of your printer port in the table above.
