1. Introduction
This document is intended to descr ibe the unique features of the Inter nal SCSI
Option on LSDT scanners. This is not a replacement for the “Operators’ Reference
Guide”.
2. System Description
The Internal SCSI Option is composed of a standard LSDT scanner with an
embedded microprocessor based co nt r oller. The unit’s external interfaces consists of a
SCSI 2 connecto r , RJ-11 serial connecto r , and a rotar y switch for selecting the SCSI
ID. The scanner control program running on the internal microprocessor board
provides the interface between the host commands coming from the SCSI bus and the
scanner hardware.
During a scan operation, image data from the scanner is buffered in a circular buffer
on the contr oller. The circular buffer is 4MB or optionally 16MB. If the host co mputer
fails to read th e image data in a timely fashion a data lost er ror will occur. T h is data
lost error is unique to the internal SCSI option. The older external SCSI option was
always configured with enough internal memory to buffer a complete image.
3. Installation
Please refer to the “Operato r s’ Reference Guide” section 2 for general unpacking
and setup. However ignore the sections 2.2.4 “Installation of Data Control Board
(DCB)” and 2.2.4 “Installation of Control Interconnect Cable”
Installation of the LSDT scanner with internal SCSI option should be easy. Plug in
the scanner power, at tach the SCSI cable and select t he SCSI I D and t he system is
ready to scan. Depending on the host system software the scanner configuration file
may need to be modified using the serial interface.
3.1 SCSI Cabling
The scanner has a 50 pin SCSI-2 connecto r. Connect directly from the host interface
card or another SCSI device.
P/N 0070-275, Rev 01, LSDT INTL SCSI OPTION, OPERATORS’ SUPPLEMENT MANUAL EC2051
Form No. 0069-978, Rev 01 3 OF 16
3.2 SCSI ID and SCSI TERMINATION
There is a small rotary switch on the back of the scanner next to where the SCSI
cable is connected. This switch selects bot h t he SCSI I D and enables SCSI bus
termination. SCSI ID’s range from 0 through 7. Every device on the SCSI bus must
have a unique ID. The switch rotates from “0” to “F”. Switch values from 0 through
7 select SCSI ID = value, with bus termination DISABLED. Switch values from 8
through F select SCSI ID = (value - 8), with bus termination ENABLED. For example
if t he rot ary sw itch is set to “C” then the scan n er will res pond to SCSI ID 4 with the
SCSI bus termination ena bled.

3.3 Hardware Configuration
Normally no hardware co nfiguration is required. The microcontr oller interface board
has 4 jumpers (JP1 , JP 2 , JP3, JP4) . Jumper JP1 is really a connector for a r e set butt on,
if jumped the syste m will not run (c on stan t re set). Jumpe rs JP 2 and JP3 are used to
configure the memory size. Jumper JP4 enables the SCSI bus state indicator LEDs.
When JP4 is enabled the LEDs show t he curr ent S CSI bus state. S ince the LEDs are
located inside the scanner they are only used for tro uble shoot ing.
WARNING: If JP4 is enabled th e LED s will cause stra y light that will adv erse ly effe ct
t he image qua lity.

3.4 Scanner Configuration (LSDTCONF.DAT)
The s c anner ha s sever al minor configura tion options. The file D: \LSD TCON F .DAT
on the internal controller defines all user configuration options. There ar e 7 option
parameters: protocol, inquiry type, target SCSI ID, wait for digitize, mode, film
present, and request sense length. The meaning and syntax of each parameter is
described in the following sections. The factory default sett ings are corr ect for the
majorit y of user s.
Example LSDTCONF.DAT file:
Protocol LUMISYS ; LUMISYS or ANSI
Inquiry_Type ANSI ; LUMISYS or ANSI
TARGET_SCSI_ID 4 ; from 0 through 6 are valid
WAIT_FOR_DIGITIZE FALSE ; either TRUE, or FALSE
; TRUE -> more like LS150/200
MODE NORMAL ; INTERRUPTABLE/NORMAL
; INTERRUPTABLE returns busy
; on image data reads when no
; data is available. Host must
; retry.
; NORMAL holds the SCSI bus
; until data is available.
FILM_PRESENT NO ; TRUE or YES if sensor present
REQ_SENSE_LENGTH 0 ; Non-Zero overrides response length
3.4.1 Protocol
This parameter sele cts the scanne r c ommand proto col, cu rren tly on ly “ LUMI SY S”
is supported.
Default = LUMISYS
3.4.2 Inquiry Type
This parameter selects t he format o f the Inquiry response data. Legal values are
“LUMISYS” or “ANSI”. It is highly recommended that “ANSI” be used. The correct
value is determined by th e host so ftware. So me host so ftware will ex cept eith er format.
Default = ANSI
P/N 0070-275, Rev 01, LSDT INTL SCSI OPTION, OPERATORS’ SUPPLEMENT MANUAL EC2051
Form No. 0069-978, Rev 01 5 OF 16
3.4.3 Target SCSI ID NOT USED T his parameters is provided only for compatibility w ith previous
version of the scanner. The SCSI I D is set ONLY using the rotar y switch at the back of
the scanner.
3.4.4 Wait for Digitize
This parameter det er mines the behavior of the scanner when a Digitize command is
received. Legal values are “TRUE” or “FALSE”. Most host systems prefer FALSE,
but a value of TRUE cause a more LUMISCAN 150/200 like behavior.
Default = FALSE
3.4.5 Mode
This parameter determines the behavior o f the scanner when a Receive Data
command is processed and the is no dat a cur r ent ly available. Legal values are
“NORMAL” or “INTE RRUP TABLE”. A setting of NORMAL causes the SCSI bus to
be held bu sy wh ile w aiting for the image data. While th e S CS I bus is he ld no othe r
SCSI device can be accessed during the 8+ seconds that it takes to load the film fo r
scanning. A sett ing of IN TER R UPT AB L E re turns a BUSY c ondition and the host
must poll until data is availab le. Most syste ms will scan co rrectly with either value, but
general host system performance could be affected. The corr ect value is determined by
the host system.
Default = NORMAL
3.4.6 Film Present
Th e setting of the p ar ameter s ind icates to the scanner the pres ence of a film presen t
sensor in the hardware. The factory value for this parameters should not be changed
except by a field service person insta lling a hardware upgrade.
Default = (depends are act ual hardware, TRUE if detecto r is present in hardware)
3.4.7 Request Sense Length
This parameter allows the length of the response to a “Request S ense” command to
be overridden. The correct value is determined by the host software. Don’t change this
parameters unless your host software requires it.
Default = 0

4. Diagnostics
There are several diagnostic and maintenance programs that may be executed to
keep the scanner pe rformance optimal. At this time all diagn ostics must be run by u sing
internal “c ommand line utilities ”. To access the microprocessor a terminal, or a
computer running a terminal emulation progr am, should be connected to the serial port.
4.1 Serial Port Setup
At the back of the scanner, next to t he SCSI connector is a phone jack (RJ-11)
connector for an RS-232 serial line. This serial line uses a “3 wire” connection. Only
the transmit, r eceive, and ground wires are used. This port is set for 9600 baud, 8 bits,
No Par ity, 1 st op bit. (Note: some systems may be set t o 56K baud). T he serial port is
used to access the internal microcontro ller for system configuration, maintenance, and
diagnostics.
4.2 Scanner Control Program
Normally when the scanner is powered o n t he main contr ol program is executed.
Th e ma in pro gram is named “ LS DT ISO.EXE” . For hist oric al r easons it is some times
called LSDTS CS I. The L SD TISO p rog ra m takes command input from the SC SI bu s
and translates it into control oper ations for the scanner hardware. Image data is taken
from the scanner ha rdware, buffere d in onboard memory, a nd the n sent to the host.
When a terminal is attached to the serial port , input is received and process by the
control program. The LSDTISO prog r am accepts several single key commands: X, O,
D, F, L, and Q. These commands are case sensitive.
‘X’ - dump internal SCSI interface chip registers
‘O’ - display status of internal FIFO error flag (good or overflow)
‘D’ - enable/disable screen debugs (toggle), internal program status info
‘F’ - enable/disable SCSI commands (toggle), data, and status display
‘L’ - dump internal DMA controller registers [CAN CAUSE ERRORS]
‘Q ’ - qu it pro gr am, ex it to c ommand line pro mpt.
Note: the ‘L’ command can cause data loss and other erro r s if used while the
scanner is transferring data, DMA active.
Normally only the ‘Q’ quit command is used to get access to the command line
diagnostics.
Sometimes the ‘F’ Formatted SCSI data dump command may be used to try and
diagn ose syste m setup of h ost progra mming pr ob lems.

4.3 Command Line Maintenance and Diagnostics Utilities
Th e c ommand line utilit ies ar e access through the serial interface. After connecting
to the serial port , type ‘Q’ to cause the cont r ol program “LSDTISO” to exit. When the
“D:\>“ pro mpt a pp ears th e u tilities are r ea dy to run. A sub set of standa rd DOS
comma nds are available. When you ar e finished w ith the utilit ies eithe r reb oot the
system by power cycling, or run the LSDTISO program.
NOTE: Do NOT use the “DEL” de lete command to remove files for
the system flash memory file system. All the files on the system
are re qu ire d, miss in g file s will cause erro rs .
4.3.1 CHKCLUT - Check CLUT
The CHKCLUT program is used to verify that the CLUT file being used by the
scanner is corr ect. The CLUT file is used to adjust the pixel values to the cor r ect
optical density values. If CHKCLUT reports that perfor mance is out of specification
t he MKCLUT ut ility shou ld be run.
Th e CHKCLU T program scans a special film, called t he “step wedge ” film. The step
wedge is a film with band s of constan t den sity acr oss the film. A t ext file, called th e
“density file”, containing a list of the actual density vales for each wedge is read. The
program then compares the pixel values in the image with the “true” density values.
CHKCLUT serial_number density_tag
se ria l_numbe r - syst em ser ial numbe r, provide for compatibility, not used
density_tag - the unique specifier for the density filename. See the MKCLUT
description.

Form No. 0069-978, Rev 01 8 OF 16
4.3.2 MKCLUT - Make CLUT
The MKCLUT program is used to create a CLUT file from scratch. The CLUT is a
lookup table that corr ects the raw pixel values to there true o p tical density values.
Th e MK CLUT pro gr am scans a special film, called t he “step wedge ” film. The step
wedge is a film with band s of constan t den sity acr oss the film. A t ext file, called th e
“density file”, containing a list of the actual density values for each wedge is read. The
program then compares the pixel values in the image with the “true” density values. By
using the differences between scanned pixel values and the true values, a co r r ection
LUT is generated. T his correction LUT is the “D:\CLUT0000.DAT” written to the
flash file system.
MKCLUT serial_number density_tag
se ria l_numbe r - syst em ser ial numbe r, provide for compatibility, not used
density_tag - th e unique specifier for the density filena me. The den sity file co nt ains
t he actual op tical densitie s of the step wedge film.
density filename = “DEN[density_ tag].DAT”
Example:
MKCLUT 0000 L15
uses density file “DENL15.DAT”
4.3.3 CHKMTF - Check MTF
Th e CHKMTF progra m is used to ve rify that t he s ca n ner is performing within
sp ecification s. This prog ra m re qu ire s the special “M TF” test film, an 8” by 10 ” film
with a group of vertical lines, a center black square, and a group of horizontal lines.
CHKMTF serial number
se ria l_numbe r - syst em ser ial numbe r, provide for compatibility, not used
4.3.4 CHKXYLIN - Check X/Y Linearity
The CHKXYLIN program is used to verify that the scanner linearity is within
specifications for both the X (pixels) and Y (lines) axis. This program requires the
special “Line ar ity” test film, a wh ite 14” by 17” film cr isscrossed b y X/Y lines spaced at
half inch intervals. This program detects the lines and measures there spacing.
CHKXYLIN serial number [threshold]
se ria l_numbe r - syst em ser ial numbe r, provide for compatibility, not used
t hresh old - optional th reshold multiplier value (default 1.25). This op tion is only
used in special circumstances where the lines on the XY pattern are not being detect ed.

Form No. 0069-978, Rev 01 9 OF 16
4.3.5 LNADJDT - Adjust X Linearity
The LNADJDT program is used to adjust the scanner X (pixel) linearity. This
program should only be used by a trained Field Service person.
4.4 Command Line Tools
The command line to ols are used to enable system maintenance and diagnostics.
These tools do not directly effect the scanner hardware.
4.4.1 EDDEN - Edit the Density file
The EDDEN prog r am is used to create and modify the density files used by
MKCLUT and CHKCLUT on the Internal SCSI scanner.
Command line:
EDDEN densityFile
where " de nsityFile" is t he actual file na me of the de nsity value
file. If you use MKCLUT/CHKCLUT as follows:
MKCLUT 9999 014
then the "densityFile" should be "DEN014.DAT"
example:
EDDEN den014.dat
Commands:
D num - DELETE wedge entry
nu m = wed ge numb er to delete
E [num] - EDIT / Entry mode
num = optional wedge number to start editing
H - HEL P display list of comman ds
P - P RI NT display the complete list o f de nsity file values

4.4.2 ED - Simple Line Editor
ed - line-oriented text editor , simila r to UNIX V7 ed
ED is a ve ry s imple lin e editor . It can be used to ed it all the text files used by the
internal controller system, even the density file normally edited by EDDEN. Nor mally
ED is only used to modify the LSDTCNFG.DAT file.
4.4.2.1 ED Syntax
ed [existing-file]
existing-file Only an existing file can be opened. Otherwise
a nameless edit buffer is opened; a name can be used with
the ‘f’ or ‘w’ commands.
As a line editor, ed operates in one of two modes: COMMAND mode, in which a
colon is displ ayed at the screen’s bottom to prompt for a command; and INPUT
mode, in which all keyboard input is added to the file (edit buffer). From
COMMAND mode, INPUT mode is entered by either the ‘i’ or ‘a’ commands.
From INPUT mode, the COMMAND mode is restored by entering a line
consisting of a singl e period by itself. If such a line is desired in the file, it can
be created by entering (for instance) two periods, then using the ‘s’ command to
change these to only one period.
A command consists of an optional line-range specification, a single character
indicating the command, and for some commands an optional third argument.
The line-range specification is either a single line number or a first-line number
and a last-line number separated by a comma. The character ‘^’ means the first
line of the file; ‘$’ means the last line of the file.
If the input command does not process correctly the “Oops” error message will
be displayed.
4.4.2.2 ED Commands
<newline>
If a line is specified, make that the new current line.
Otherwise advance the current- line-pointer by one line.
= Print the line number of the current line.
. (b y itself) P rint the cur rent line .
