Parallel Port Setup
If the WaveBook 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: The first thing to
check is your parallel port configuration, using 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 95/98 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. Click once to highlight the line containing the LPT port you chose to use with your WaveBook in the
Configuration utility.
7. Click the Properties button.
8. The Device Status section should contain the message "This device is working properly". If not, 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 WaveBook use with
the Configuration utility.
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)
Note: If the settings do not correspond to those in the above table, or if there is no "Interrupt
Request" entry, follow these steps:
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.
11. The "Conflicting device list" section should contain the message "No conflicts". If not, and a DMA
conflict is described, repeat Steps 10a - 10c but change only the DMA setting.
12. If one or more conflicts are described in the "Conflicting device list" section, you must find the
conflicting device(s) and change the conflicting resource(s) by following these steps:
12a. Take note of all conflicts, then click the OK button.
12b. If a window appears titled "Creating a Forced Configuration", click Yes to continue.
12c. Open the conflicting device type by clicking on the "+" in the small box to its left, if necessary.
12d. The conflicting device's icon should be marked with an exclamation point in a yellow circle.
Click once on the device to highlight it; then click the Properties button.
12e. Click the Resources tab.
12f.
Perform Steps 10a - 10c to resolve the resource conflict.
12g. Repeat Step 11 for each additional existing resource conflict.
