OPOS Drivers basically consist of these two layers:
With the PREH OPOS driver you can easily communicate with all PREH keyboard extension modules under Windows operating systems.
The actual version is able to control the following modules:
Further detailled information on the latest version of the Preh OPOS Driver can be found in the file Readme.txt. This file is displayed when starting the installation. Additionally it can be reviewed after installation by a start menu shortcut.
Attention!
Before starting installing the OPOS drivers, you should read the
important annotations regarding the system requirements
at the end of this document.
Before using the OPOS driver you need to install the Common Contol Objects as well as the PREH Service Objects.
We have included the Common Control Objects Version 1.10.001 installer into this package. Please Note: For the Preh OPOS driver demo applications it's recommended to have installed the CCOs version 1.4 or above.
The common control objects have been developed by Curtiss Monroe Copyright, (c) 1999-2007 RCS, Inc.; Dayton, OH. Informations and updated versions you can find at http://www.monroecs.com.
To install the Common Control Objects please run this installer file:
"OposCCOs-1_10_001.exe"
To install the PREH Service Objects please run this installer file:
"Opos0110007b.EXE"
During the installation process of the OPOS drivers, a detailed OPOS
online help will be generated automatically.
Within this help you can find descriptions about OPOS properties and
events of all modules.
Attention!
The OPOS sample files can only be executed if the OPOS driver is
allready installed on your system.
In addition to the OPOS driver, the PREH keyboard modules must be
programmed with the OPOS-specific headers and terminators. For doing
this you should use the latest WinProgrammer version.
If you want to send commands towards the PS/2 keyboard under WindowsNT,
2000 and XP, the PREH PS/2 keyboard driver must be installed properly.
Start the sample applications using the appropriate start menu entry. Further detailled information can be found in the file Readme.txt.
For the modules magnetic stripe reader (MSR), keylock, line display (LCD)
and for the POSKeys easy sample files are available for Microsoft Visual
Basic and VisualC.
The executeable file as well as the sourcecode can be found in the appropriate
subdirectories.
For uninstalling the PREH OPOS-Treiber please launch "Add/remove programs" in the control panel.
The following operating systems can be used:

Annex: Content of the file Readme.txt for PREH OPOS Driver for Windows V1.10.007b:
============================================
PREH OPOS Driver for Windows 1.10.007b
============================================
When using notepad you should activate "word wrap" for correct view of this file.
0. System Requirements
======================
Operating systems supported:
Windows9x, Windows NT4.0, Windows 2000/XP
The OPOS Common Control Objects (CCOs) must also be installed in addition. Please Note: For the Preh OPOS driver demo applications it's recommended to have installed the CCOs version 1.10 or above.
Preh keyboard or module configured to "OPOS settings" - see chapter 2.
1. Installation
===============
Just follow the installation wizard.
The installation of the "Preh Driver Pack" is recommended. This package is included and will be started automatically at the end of Preh OPOS Driver setup procedure, if the included DriverPack version is newer than the installed one. If the version is same or older you should not install the driver pack again - except: see 6. Troubleshooting.
If one of the older Preh packages OPOS/JavaPOS previously was installed, some settings might be overwritten by default values during the DriverPack installation.
We recommend to uninstall all older Preh OPOS/JavaPOS packages which did not contain any Preh DriverPack before continuing (e.g. Preh OPOS Driver V1.4.46).
You need to have administrator rights to replace the Keyboard Driver within Windows NT and Windows2000/XP.
2. Configuring the Keyboard using the WinProgrammer
===================================================
To use OPOS driver you need do configure keyboard's modules to OPOS settings, if not already done.
The Preh keyboard's modules (MSR, Keylock, POSKeys, etc.) must be programmed using the Opos headers.
This is done in the Preh WinProgrammer by enabling the option "OPOS settings" when creating a new keyboard layout.
The PosKeys are programmed using the Macros {POSKey001} ... {POSKey128} - usually on StdKey-Layer with Autorepeat OFF.
Finally this keytable configuration must be downloaded into the keyboard.
Notes:
For common Preh keyboard types you can find some ready-to use sample keytables in the Preh WinProgrammer:
Please use the appropriate configuration from WinProgrammer's subdirectory .\Keytables\OposJavaPOS.
3. Usage / OPOS Demo Applications
=================================
For each supported OPOS device you can find a sample program to demonstrate the capabilities.
Please start the sample application using the appropriate start menu icon.
Then just use the usual steps (Open / Claim etc.).
The Default Device Names for Preh Keyboard's modules are:
* "PREH POSKeyboard"
* "PREH MSR"
* "Preh Keylock"
* "PREH Tone Indicator"
* "PREH HSMSR" for RS232 msr module
* "PREH Line Display" for old LCD module of MWX and MC/WX keyboards
* "PREH Scanner" for scanner module of MWX and MC/WX keyboards
The Names of OPOS Devices are set in Windows Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS\
Please Note:
Behaviour of demo applications for MSR and PosKeyboard was changed in version 1.10:
Activated option "Automatic Enable" causes the demo app to always re-enable DataEventEnabled after DataEvent.
The MSR demo application behaviour was changed in version 1.4.0.50:
Now the application does not automatically execute "GetTrackData" in case of an error event being recorded.
To retrieve the data of the "healthy tracks" in case of an error event, click onto the track fields in the dialogue.
4. Special System Configuration
===============================
4.1 Interface Settings
======================
The Keyboard interface setting is located in the Windows registry. For changing the interface you have to change the registry key.
This can be easily done by importing regkeys. The registry key for the interface is located at:
HKEY_LOCAL_MACHINE\SOFTWARE\PREH\Keyboard\INTERFACE
0x00000000 = PS/2 Interface
0xffffffff = USB Interface
For special older keyboards with RS232 interface also:
0x00000001 = RS232 Schnittstelle COM 1
0x00000002 = RS232 Schnittstelle COM 2
0x00000003 = RS232 Schnittstelle COM 3
0x00000004 = RS232 Schnittstelle COM 4
4.2 LowLevel Keyhook for PS2
============================
This feature was added in Driver Pack V1.1.0.0
It is only available for Windows NT4.0(SP3)/Windows 2000/Windows XP.
The automatic starting/closing of the server application using Registry Key "LLKeyhook" is only supported by package Preh JavaPOS.
The Preh Keyboard Server for PS2 can also be started manually by running "PrehKeySrv.exe".
"PrehKeySrv.exe" is installed in DriverPack subfolder "...Preh\DriverPack\ps2"
An active server application is indicated by a Preh icon in the Windows Systray.
Tip: Automatically start the Preh Keyboard Server for PS2 during Windows startup:
* Either placing a shortcut to PrehKeySrv.exe in the Windows' Startup folder -or by-
* Using the following "Run" entry (REG_SZ) in the Windows Registry:
SOFTWARE\Microsoft\Windows\CurrentVersion\Run
"Preh PS2 Keyboard Server" = "C:\Program Files\Preh\DriverPack\ps2\PrehKeySrv.exe"
In the Preh OPOS installer V1.4.0.52 a dialogue "LowLevel Keyhook" was added.
If selected, such Run key is automatically added to the registry.
Note: When using unattended installation such registry key is not automatically generated.
4.3 POSKeyboard Translation
===========================
The DataEvents result codes can be translated into user defined codes.
This is a requirement of the OPOS standard (please see OPOS documentation).
The appropriate registry keys are located here:
[HKEY_LOCAL_MACHINE\SOFTWARE\OLEforRetail\ServiceOPOS\POSKeyboard\PREH POSKeyboard]
"POSKey001"=dword:00000001
...
"POSKey128"=dword:00000080
In previous packages this keys could be added manuall or using some Registry files:
.\util\PosKey_128.reg
.\util\PosKey_default.reg
In the Preh OPOS installer V1.4.0.56 a dialogue was added to configure the POSKeyboard:
The first option activates a translation table for the Preh POSKeyboard which results in continuous codes matching the programmed keyboard macros {POSKey001} .. {POSKey128}.
The second option does not modify the translation table. Basically you will get hardware specific non-continuous codes.
For unattended installation this is configurable using the option "KB_TRANSLATE". For details please refer to "Auto_install.txt".
5. Uninstall
============
5.1 Uninstall the Preh OPOS driver using Windows Control Panel -> Add/Remove Applications.
5.2 If no more needed, you also can remove the package "Preh Driver Pack" the same way. Attention: If other packages are installed on this computer which still use this drivers (like Preh JavaPOS, etc.) you must not(!) uninstall the Preh Driver Pack!
6. Troubleshoting
=================
6.1 Message: PREH 'keyhook.dll' not found
-----------------------------------------
Obviously you have installed/removed a older software package (e.g. Preh OPOS Driver V1.4.46) after installing the driver pack. By doing so, several Windows registry settings were removed, which are required for the functionality of the PREH system files "keyhook.dll".
=> Solution: (Re)Install the latest version of the Preh DriverPack.
6.2 The codes for POSKeyboard data event are not continuous
-----------------------------------------
You should use POSKeyboard Translation as described in chapter 4.3.
