1. From the Windows Control Panel select the Leica Imaging application the one that has the Leica logo this shows the Server select dialog Select the required driver from the Image Server configure dialog gt Select Image Driver Select Preview and see that the DC Twain window appears Now check OFF the DC Twain selection and check ON the Peripheral server and install it Please use the DM microscope SDK that is automatically installed from the Server CD Make sure you select the correct radio button for the model of DM Microscope you will be using If you have a later version e g V4 13 please completely uninstall this Also you must manually remove the remaining configuration files Step 3 If all is OK so far you should now be able to install the IA software as normal n Refer to Read the Release notes on the CDs before you start the installation A Hints If you have messages on starting the camera suggesting that the camera is not connected when it obviously is try closing the application and rename the LastUsed configuration file from the folder WinNT Twain_32 LeicaDC If these files are corrupt or not compatible the cameras will not start DC300 resolution is high and can be used with Leica QWin However you cannot see the whole image on the screen at full resolution so the DC300F and DC350F are better choices to use with Leica QWin With Leica QWin when using high res cameras go to preferences and check on all the f2. uninstall is performed Also rename as old the configuration files in the Twain32 directory these are not necessarily compatible with a different version of DC Twain Install the DC Camera software first carefully following the instructions provided on the CD Make sure that this is working correctly e g using Windows Imaging PaintShop or IM 50 before installing Leica Servers Leica DC Camera with lA applications 1 Installation advice Issue 2 Feb 2002 Note If the cameras are not working do NOT proceed You will only compound any problems You must have the DC Cameras working independently of the IA applications before you install the IA applications Check the camera installation as described on the DC camera CDand retry the installation Step 2 Install Server CD You will find the user manual for the server on the CD Read it before proceeding Note Only install one server component at a time and check it is working correctly before you install another component You should only have one tick box set for installation at a time Warning the uninstall button will remove ALL servers not just those with ticks new to them Use with extream care Install Leica DC Twain from the Server CD Do not install the old drivers for DC cameras using PCI3 interface boards these boards are not compatible Do not re install any other drivers from the Server CD at this time for example M eteor drivers M ake sure all are checked OFF
