Using the BIOS menus provided, change the port mode to EPP or EPP+ECP. Please note the

mode cannot be set to the ECP only mode (or any other selection such as SPP, Bi-directional,

or Standard), as these will not work. If you cannot find an EPP mode selection, the EPP2000

will not work. An EPP-PCI or EPP-PCMCIA card is needed.

Using the BIOS menu, verify the LPT port address (normally 378 hex). Later, set the

SpectraWiz Setup => Interface port configuration to the same port address.

After setting up your BIOS and verifying the Port and IRQ settings using the Windows Device

Manager Goto step 1.

DOS SpectraWiz

If you are operating under Win9x/ME it is a good idea to verify the adapter port installation

using Windows Device Manager. Please note that an IRQ assignment is required. Next open

a Dos window and continue as follows:

Insert the SpectraWiz (Dos) diskette and run a:INSTALL.BAT. This creates a directory on

your hard drive named C:\SW and copies all files into it.

Change directory into c:\SW (“CD \SW”) then type the command SWZ. This will start the

SWZ.BAT file. It performs the basic setup required for operation on LPT2: then runs the

SW.EXE. To use a port that is configured for LPT1 (378 hex IRQ7), execute the SW1.BAT

file instead.

If you are running Windows you may wish to create a shortcut to the SWZ.BAT

file using the Windows Explorer and place it on your desktop. For proper

SpectraWiz operation, the Memory properties should be all set to Auto. The

Conventional memory Protected option should be enabled. Both EMS and

XMS set to Auto and Uses HMA should be checked(enabled). Under Misc

properties-> Foreground -> Allow screen saver set unchecked(disabled).

EPP2000 Hardware Interface

The DB25 connector on the rear panel of the EPP2000 communicates with the connected

computer using the IEEE 1284 protocol for Enhanced Parallel Ports (EPP). Since the unit

provides over 2000 wavelengths for a single scan request, we called it the EPP2000. The IEEE

1284 interface specification is really a hardware handshake mechanism that allows high-speed

data transfer into and out of the computer.

Older PC’s did not support the bi-directional EPP transfer mode on the printer port. Most of

the newer PC’s (after 1995) do support this mode, however there are always a few exceptions.

Even though the IEEE1284 standard is published, there are a few PC’s that don’t work just

right (even thought they say they do). They may only support the ECP mode but not the EPP
