Slide Scanner Service

For technicians!

The service program (SlideScannerService.exe; SSS) is an essential tool to setup, install and test the scanners P250, Pannoramic SCAN, MIDI and DESK and is used for service actions of any kind. It allows also the move of connected units separately (not the entire scanner must be connected). The “Multi USB” dialog, shown after startup, allows configuring the service program for more scanners or units; the differentiation is done by the serial number of the USB controller unit. In other words, the technician may connect maximal 4 USB controllers at the same time. The hardware, connected to the USB controller may be an entire scanner or hardware units only, to be tested or moved. In such cases, the appropriate file “MicroscopeConfiguration.ini” is assigned to the appropriate USB controller. To avoid unauthorized use, the service program is license protected.

The description of the tools and options is based on the software version 1.17 and 1.18.

· Differences according to the actual scanner and special dialogues are explained separately.

Setup “SlideScannerService.exe”

The service program will be installed automatically during the installation of the scan program “SlideScanner.exe”; see also: “Setup the scan program”.

Attention: Do not mix the versions of SlideScanner.exe and the version of SlideScannerService.exe! Always use these programs with the same version number; otherwise the program SlideScannerService.exe could produce unwanted results and SlideScanner.exe does not work correctly or even freeze!

· This is important for the options “Brightfield preview calibration” and “Darkfield preview calibration” because these options using *.dll-files of the SlideScanner software. The options “Clear EEPROM” and “LowLevelService” working independent of the program SlideScanner.exe; therefore, if these options are used only, the version number is less important.

Requirements and start the service program

· Valid license file: “MService.lic” in the folder: C:\Program Files\3DHISTECH\SlideScanner\

· Before starting the software “SlideScannerService”, the USB driver has to be installed!

· Start the program “SlideScannerService.exe” by clicking the icon “SlideScannerService.exe” or from its folder.

For the actual path (folder) of the service program please refer to “Paths and locations”

If the license file is not recognized or invalid, a message “Missing license” is displayed.

· Please check the presence of the license file; see “Paths and locations”

· Please check the validity of the license file

Check the validity of the license file

Open the license file MService.lic with any text editor (e.g. Notepad or WordPad) and check:

· the expiration date and

· licensed options

Scanner types

To avoid confusion, the scanner type is recognized automatically by the service program (and the scan program of course) during start up; only the tools, needed for the appropriate, connected scanner can be reached; see also the parameter ”MicroscopeType” in the section [Microscope] of the file “MicroscopeConfiguration.ini”.

The found parameter value in the found “MicroscopeConfiguration.ini” decides the available options.

The microscope type is checked during the start of the service program and is true for all options of the selector menu; especially important in the “Low Level Service” part.

The microscope type can be

MicroscopeType= 3DMic4 MIRAX SCAN microscopes before the year 2006; equipped with the preview camera “Logitech QC 4000 pro”.

3DMic5 MIRAX DESK and Pannoramic DESK

3DMic6 MIRAX SCAN, the magazine has 50 slide positions and is equipped with the preview camera “DFK 21F04”

Preview Calibration

This part of the service program is an interactive tool and calculates the physical position (distance) of the preview camera in relation to the scan (main) camera.

More, detailed information can be found in the chapter

S_M_D: “Preview S_M_D” and “Steps of preview calibration”

P250: “P250_preview” and “Brightfield preview calibration procedure”

Low Level Service

This part of the program allows the handling of the components in a very high degree of freedom; see later in this description.

Clear EEPROM

This option clears the EEPROM content.

The EEPROM stores the scanner specific parameters and these are collected in the files “MicroscopeConfiguration.ini” and “MicroscopeSettings.ini” as well. To ensure an always proper function of the scanner, the content of the EEPROM should be updated after adjustments are done or units are exchanged and parameter values are modified.

· To update the content, the EEPROM must be cleared first; see also: “Clear the EEPROM”.

Darkfield calibration

This option uses a software algorithm to calibrate the darkfield preview.

Please refer to the chapters “Darkfield preview”, “Darkfield preview calibration” and “Calibrate the darkfield preview”

Exit

This is leaving the service program.

Clear the EEPROM

Answer the question with “Yes”.

· If the scan software “SlideScanner.exe” is started and the EEPROM is empty, the content of the appropriate *.ini files is written automatically from the actual folder of the HDD into the EEPROM, during the startup procedure of the program “SlideScanner.exe”.

· The path of the *.ini-files, used to update the EEPROM in the version with the operating system Windows® 7 is:

C:\ProgramData\3DHISTECH\SlideScanner\MicroscopeConfiguration.ini and MicroscopeSettings.ini

· In the version with the operating system Windows® xP is:

C:\ Documents and Settings\All Users\ApplicationData\3DHISTECH\SlideScanner\MicroscopeConfiguration.ini and MicroscopeSettings.ini

1. Start the program “SlideScannerService.exe”, option “Clear EEPROM”.

2. Answer the dialogue with “Yes”; then the EEPROM is cleared.

3. Leave the selector dialog with “Exit”

4. Start the program SlideScanner.exe; the *.ini-files will be saved automatically from the appropriate HDD folder into the EEPROM during startup the program, if the EEPROM is empty.

Low Level Service

Top line

After selecting the option “Low Level Service = LLS” the connected scanner type (Pannoramic 250), the serial number of the connected USB controller (11200261) and the version number of the service program (1.17.0.31917) is shown in the top line. The scanner type is derived from the found “MicroscopeConfiguration.ini” file; see also above “Scanner types”

Construction of the screen

The upper half of the screen contains the usual options like “X-Motor”, “Y-Motor”, “Focus-Motor” and “Turret-Motor” tools, during the lower half of the screen contains scanner specific units like DC controller, Objective changer and other special tools.

All the units of the scanner can be driven independently from each other; the technician defines the action without limits (the limits are given by the hardware limits of the construction).

· Because the sensors are handled in polling mode, the different units of the scanner may be connected or disconnected (can be switched active or inactive (Reset)) separately to save execution and response time.

Important

To spend a very high degree of freedom for the Low Level Service part of the program, only small software protections are implemented (and in addition, these can be overridden)!

The technician has to select carefully the action to be executed, otherwise units might be damaged, bend or made unusable.

The Low Level Service includes:

· Set the stepper motors to Home1,2.

· Check the functionality of the sensor Home2.

· Move any stepper motor a predefined or user defined number of steps; forward or backward respectively.

· Showing always the actual rotor position in steps, proceeded from Home1,2.

· Driving the DC-motor's rotor forward or backward as desired for the action requested; the stop event may be:

- The sensor action or

- The predefined runtime evaluated (named as Timeout)

· Showing always the actual state of the sensors.

· Switching on or off illuminations

· USB status monitoring

· Checking and monitoring the status of the unit, defined as “active”

· Displays the serial number and the electronics version number of the connected unit

· Stop of all movements in emergency situations.

Common tools

Global unit control

Active

Allows the use of the appropriate unit and switches it into the active state. The service program starts the communication with the motor or unit electronics. During this action the serial number of the motor and the firmware version with date is read out from the motor electronics.

By dragging or scrolling in the alphanumeric field the not shown part of the content can be displayed.

State

On the right hand side of the appropriate unit, the current position of the sensors Home1 and Home2 are shown; for information about the stepper motors and the sensors Home 1 and Home2 please refer also to the chapter “Stepper motor implementation” in the file “USB- and DC-controlling” and “Sensor Home1” and the hardware limits”.

Reset

Is used to switch inactive the appropriate unit if it’s not in use; so the response time of the other, active units is reduced.

Advanced

A dialogue with special parameters of the unit will be opened.

This option is used in special conditions only; the default values are meeting almost always the setup conditions. Exceptions will be discussed separately; in the part of the appropriate unit.

Emergency stop

In any cases, if mechanical jamming occurs, all actions in progress are stopped.

· Press this button if any action has to be stopped in emergency situations.

· The “Emergency power off” (P250) or the power switch for the power supply (S_M_D) can also be used to abort any movements.

Important “TaskManager”

Rotor movement tools

The movement of the stepper motor’s rotor is realized with predefined step number buttons.

· In special conditions, and to reach any required position, the user can also define a number of steps to go, any time.

Motor steps

The actual position of the rotor is shown in a number of steps in distance to the position Home1,2.

If the appropriate unit is active, the content of the step counter is shown; see also “Motor steps”.

X-direction

The buttons are arranged horizontally like the mathematical X-axis; ; see also “X-direction tools”.

Y-direction

The buttons are arranged vertically like the mathematical Y-axis; see also “Y-direction tools”.

Activate all

All the motors and controllers are switched to the active state. This action is identical with the procedure to press the button “Active” for each unit separately.

Focus

The nominal center of the focus range is exactly 1600steps (in S_M_D) ; see also “Focus motor tools”.

Filter

The filter wheel of the reflector turret unit is driven by the use of these buttons.

The distance of two filter positions is exactly 6400steps in the gear driven RTU; see also “FL reflector turret tools”.

Home1, Home2

By pressing the button Home1, the rotor finds the start position inside of 1 revolution.

By pressing the button Home2, the entire mechanical drive is moved to its home position and by pressing the button Home2 second time, the step counter will be cleared.

See also “Home1,2”.

Motor steps

This part shows the step counter content of the appropriate motor.

· In this part the actual position of the rotor is shown for the stepper motors.

· If positive numbers are shown, the position of the rotor is identical with the step counter content.

· Negative numbers showing always the step counter content as a deviation in steps from the Home1,2 state in negative direction.

· If the appropriate motor is switched active and the Home1,2 position was found, the background is shown in green and the content is “0”; see (A).

· If the unit is in active state but the commands Home1,2 was not executed yet, the background is shown in white with “0” or any number; see (B).

· If the unit not reached the position home1,2 after issuing the command Home1,2, the background is shown in red; press the button Home2 again to reach the Home1,2 state; see (C) (focus motor with 6400steps/revolution). Press the button Home2 again, until the background is shown in green!

· If the unit is in the reset state, a single, grey “0” is shown on white background; see (D).

· The Z-position shows the actual number of steps of the focus unit motor.

“How to define hardware limits” “Sensor “Home1” and hardware limits” and “Stepper motors”

Rotor movement tools

The control of the stepper motor is done with the following tools; these existing for each stepper motor separately.

Home1,2

After switching active the appropriate motor, the home position of the motor (and the entire mechanical construction) have to be found by pressing the buttons Home1 and then press the button Home2. Use this sequence also, if the home position of the entire mechanical construction should be found any time.

If the mechanical drive should be checked for lost steps, press Home1 only. If there are no steps lost (+2 or -2 steps tolerance are maximal allowed); the number of actual steps should be “0” (zero) or a multiple number of 3200 steps.

“Sensors”, “Stepper motor implementation” and “How to define hardware limits”

Home2 test

This button is used to check the correct acting range of the sensor Home2.

· If the remark shows “bad”, the unit may work correctly, but the acting range of the sensor “Home2” is outside the nominal limits.

“Principle of sensor Home2”

Predefined step numbers

These buttons are used to move the rotor by 1 revolution, a half revolution and by 100 steps forward or backward respectively. If the button of the predefined number of steps is pressed, the number of steps is done from the actual rotor position in positive or negative direction.

“Motor steps”

User defined step numbers

If the desired number of steps can not be reached with the predefined step number buttons (or the buttons should be pressed very often to reach the desired position) the user can define in the numeric field a number of steps to go.

· Easily type in the desired number of steps to go into the appropriate numerical field

· Press the corresponding buttons without step number in positive or negative direction, the number of steps is executed from the actual rotor position

This possibility is often used if the hardware limits have to be defined or checked.

Important

· This options can easily create mechanical jamming or lost steps (as any other step number button also) if the number of steps to go is not calculated correctly.

· The directions forward and backward are defined in relation to the movement of the mechanical drive; the home position is always near to the negative limit

· Creating lost steps can be used to find the correct hardware limits!
