INTRODUCTION
|
||
MICROTEK is an image processing software package that enables you to operate Microtek Models-300 and 300A Intelligent Image Scanners with the Xerox 1108 and 1186 workstations. The Microtek MS-300, 300A, and MSF-300C are high-resolution optical scanners that can convert text, artwork, photographs, etc, into digital form for processing by computer. The digitized images that are output to the computer contain up to 300 black and white dots for every linear inch of the original document. Page size can be as large as 8.5 by 14 inches. Sophisticated firmware in this scanner enables the user to set the scanning area and control brightness, contrast, scaling, shading and other characteristics of the scanned images through simple commands transmitted from the 1108 or 1186. Two basic scanning modes are supported: Line Art mode for accurate capture of completely black-and-white material, and Halftone mode for faithful reproduction of material with varied shading. Mixed-mode scanning is also available.
|
||
With the MICROTEK software package you will be able to: Set the scanner to capture images of all kinds, with desired visual effects, and transmit them to the 1108/1186, save scanned images to disk, floppy or file server for later reloading to recreate images and print scanned images to a Xerox 4045 or 8044 laser printer.

Lispuser's Packages:
|
||
ACTIVEREGIONS, ACTIVEREGIONS2, AIREGIONS, FILLREGION
|
||
HARDWARE REQUIRED
|
||
Xerox 1108 with RS232C port (E-30 upgrade kit). It is also recommended that the 1108 have 3.5 meg of memory and a floating point processor (CPE board) to enable faster scanning and creation of bitmaps.
|
||
Xerox 1186. It is also recommended that the 1186 have 3.7 meg of memory.
|
||
Microtek MS-300, MS-300A, or MSF-300C Intelligent Image Scanner with optional serial port.
|
||
CABLE CONFIGURATION
|
||
Note that the cable configuration is DIFFERENT for the MSF-300C scanner. Plugging a standard RS232C cable into the MSF-300C DB25 connector may result in damage to the equipment.

|
||
LOADING MICROTEK
|
||
Make sure that DIRECTORIES contains the directory where the required software is located. When the file MICROTEK.DFASL is loaded, the item "MicrotekScanner" will be added to the Background menu. If you have a Xerox 4045 or 8044 laser printer load MICROTEKPRINT.DFASL. If you have a Xerox 4045 laser printer load 4045XLPSTREAM.DFASL. Your 4045 laser printer should be connected to the TTY/DCE port.
|
||
RUNNING MICROTEK
|
||
The process of running the Microtek scanner software consists of three phases: Scanner initialization, scanning, and creating a bitmap of the scanned image that can eventually be printed. Each of these are controlled by different menus within the Microtek Scanner Control Window.
|
||
SCANNER INITIALIZATION
|
||
Set the Microtek scanner so that it is operating at 19200 baud by setting its internal DIP switches (See Microtek Operating Manual for details). Turn on the Microtek scanner. Select "MicrotekScanner" from the background menu and the Microtek Scanner Control window (figure 1) and Microtek Scanner Pagemap window (figure 2) will be created. (Note you may have do a control-E and retry if cursor flashes while trying to create the control window).The scanner pagemap window is used to select the area of the image to be scanned and to select the page length. The scanner control window is used to set all other scanner parameters, start and stop scanning as well as to initiate creation and printing of scanned image bitmaps. After these windows have been created, the RS232 port will be initialized to 19200 baud and an attention command will be sent to the scanner. If all cables are connected properly and the scanner is on, the message "MICROSCAN 300(A) V# is ready" will be displayed in the Microtek Status Window. If the cable is configured incorrectly or the scanner is not on or ready the messsage "Microtek Not Responding ... Check scanner and cable" will appear instead.
