ADDING AN ADDITIONAL PARALLEL PORT(S):

If you need to add additional PCI parallel ports because:

1. Other station accessories need a parallel port

or:

2. Run two (or more) WN-1 systems on a single computer, with all running simultaneously.

or:

3. Your computer did not come with a parallel port.

Then here is a step-by-step solution.

A: CAUTION: This will ONLY work with WN-1 software revision 2.0 or later. This example shows installation for the parallel card

manufactured by LAVA. These cards are Plug-n-Play on XP and XPpro operating systems, and will work with the driver

supplied on 95/98 and ME systems. There are dozens of parallel port card manufacturers, and any of them should work,

but we can't try them all. The LAVA card is one that we have successfully used in our systems.

Any parallel port card that can run SPP or ECP parallel port mode should work. Check the Wavenode "Links" page for

information on where to find the LAVA card, they run between $20 and $35.

B: Install the card and go to the device manager. You should observe that the new parallel port has been reported under the

Ports section. Figure #1 below shows the LAVA card being found by the operating system.

C: Go to the "Properties \Resources" for your new parallel port and note the I/O range addresses being used. In Figure #2 it is shown

as E800-E807. This will vary for different parallel port cards and may change if you add more peripherals to your computer.

The starting address, E800 in this case, is the one you will need to remember.

D. Go to the WN-1 software and open the configuration file. At the port selection section at the bottom-right of the screen, click on

"User Sel" and enter the starting address in the box provided. See figure 4. Now click the "Save" and "Close" button.

Your software is now configured to use this port. Plug the WN-1 cable into your new parallel port. If the front panel Interface

LED is flashing, you are ready to go. You can repeat this procedure for as many parallel ports as you need.

E. NOTE: If you wish to run two or more WN-1 systems on your computer simultaneously, you will have to install the software

in a unique folder for each WN-1. Then add a shortcut to your desktop for each copy. The reason: you will want a unique .ini

file for each copy of the software in order to personalize each screen separately for meter titles and meter scales. The .ini file

saves these screen settings for you, and is located in the same folder as the WN-1.exe file. Therefore, with each WN-1 running

its own software, each will have it's own settings saved in it's .ini file.

In this manner, you can install as many WN-1 systems on a single computer as you like and observe them all at the same time.

Figure 4 shows the configuration menu with the "User Sel." button clicked and E800 selected as the Parallel Port Address.

Remember: This Port address will change for different computers and parallel port cards. Use the "System Resources" menu of

your Operating System to find the port address for your computer.
