Parallel Port Setup (general)
If 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:
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 WaveBook.
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
WaveBook.
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 previous table, or if there is no "Interrupt Request"
entry, complete steps 10a through 10b before moving on to step 11.
a. Click on the check mark in the small box to the left of "Use automatic settings."
b. Click on the now active drop-down combo-box to the right of "Setting based on."
c. 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 this is not the
case,, 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:
a. Take note of all conflicts, then click the OK button.
b. If a window appears titled "Creating a Forced Configuration", click Yes to continue.
c. Open the conflicting device type by clicking on the "+" in the small box to its left, if necessary.
d. 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.
e. Click the Resources tab.
f. Perform Steps 10a - 10c to resolve the resource conflict.
g. Repeat Step 11 for each additional existing resource conflict.
