- Mitsubishi SC-7500 Scanner Driver
- SC7500.EXE
- Version 6.00
- January 3, 1992
-
- The Mitsubishi SC-7500 scanner driver is a Revision 6 scanner driver
- (see REV6.DOC for more information) providing black and white, gray
- scale, and color scanning for all ZSoft products.
-
- This scanner also requires an additional program named GPIB.COM.
-
- You can run SC7500.EXE from your CONFIG.SYS, AUTOEXEC.BAT, or other
- batch file. To manually add the device driver to your CONFIG.SYS,
- use a text editor to type the entry as it appears below. Be sure
- to include a path if the scanner driver is not in your root
- directory. Remember to include additional parameters when necessary.
-
- CONFIG.SYS entry:
-
- device=GPIB.COM
- device=SC7500.EXE
-
- You may also need to add an application code parameter to the
- CONFIG.SYS entry, depending on which program you are using.
- If the parameter is omitted, the application will still work,
- but may be missing some features. PhotoFinish, Publisher's
- Paintbrush version 2.02 or higher, and PC Paintbrush 5+ do not
- need an application code parameter.
-
- If you are using ...add this parameter
- this ZSoft program... to your CONFIG.SYS entry.
-
- PC Paintbrush Plus (DOS) /C1
- PC Paintbrush Plus (Windows) /C2
- PC Paintbrush IV Plus (DOS) /C3
- Publisher's Paintbrush (Windows) /C4

- This driver supports the following features:

-
- Valid commands:
-
- /Cx = application Code (1-4)
- /H = display this Help text
- /? = display this help text
- /Txxxx = do diagnostic Testing (verify communication with scanner)
- /U = Unload driver
- /V = Verbose messages and status displays
- /G<dev>= GPIB device driver name (default = DEV1)
- /0x = Transparency Mode (0-2), where 0=Normal, 1=Light, 2=Dark
-
- /G
- ==
-
- This command allows the user to specify the name of the GPIB device
- driver. The default name is "DEV1" which corresponds to GPIB address
- 1. If the DIP switches on the scanner are changed from the default
- (GPIB address 1), then a different driver name should be specified
- with /G. If, for example, the scanner is at GPIB address 7, then the
- command "/GDEV7" would be appropriate.
-
- If a valid DOS device driver is specified that is not a GPIB device,
- unpredictable results will occur.
-
-
- /0x
- ===
-
- This command enables setting the scanner for operation with the
- Transparency Unit. Normally, the scanner operates in reflective mode
- for scanning paper originals. If you wish to scan transparencies such
- as film negatives or slides, use the /0 command. /0 or /00 is used
- for normal density film, /01 is used for light, and /02 for dark.
-
- NOTE: Not all SC-7500 scanners actually support the Transparency Unit.
-
-
- Operational Notes
- =================
-
- The SC-7500 buffers quite a bit of data during a scan operation. This
- has two unusual effects.
-
- The scan progress thermometer will stay at zero, often until the scan
- head has completed the scan. At some time later, the data comes in
- and the progress thermometer begins to move.
-
- Pressing the Cancel button has no effect until the data begins to be
- received from the scanner. With small scans, the Cancel button won't
- work until the entire image has already been scanned. With larger
- images, the Cancel button doesn't work for several seconds after the
- start of the scan.
-
-
- Setting Up the GPIB Board
- =========================
-
- The following information applies to the National Instruments GPIB
- board. Other GPIB implementations have not been tested with this
- driver.
-
- If you have not already done so, run the INSTALL program from the
- National Instruments Graphics Applications distribution diskette.
- Reboot your computer and run the IBCONF program from your GPIB
- directory (the default name is \GPIB-PC).
-
- You must configure the board to use interrupts. Generally, interrupt
- 7 is a good choice. Use of DMA is optional. DMA can potentially run
- faster, but can be a source of reliability problems under Windows. Of
- course, the address must match the DIP switch setting. Do not worry
- about the other settings, as the scanner driver will set them.
-
-
