Configuring the Bentley Tablet Driver with Summagraphics Tablets TechNote

This document provides configuration instructions for the Bentley Wintab driver used with a Summagraphics tablet.

Installation Notes
NOTE: If you are using a 16 Button Cursor on a Summagraphics SummaSketch Series tablet the Bentley Wintab Driver will not work. The CalComp Drivers must be loaded instead.

Before you install the Summagraphics tablet, a mouse must be connected to the computer. If no mouse is present, the cursor will not appear when the Wintab driver is started. Also check for the 25­pin bridge adapter­­the connection must reduce to a 9­pin for MicroStation to recognize the tablet.

When the computer boots the operating system will scan for devices on the serial ports. If a device is found and a service is not loaded, the operating system will sometimes disable the serial port. The Bentley Wintab driver does not deliver a service, therefore the tablet should be turned off when starting the computer. It is possible that you could leave the tablet turned on, as some newer tablets with a Plug and Play BIOS will not cause the port to be disabled.

Checking for Other Wintab Drivers
If you had the CalComp drivers previously loaded for the Summagraphics tablet, run the CCSETUP.EXE program (found in either the driver installation directory or on the installation disk). When the installation screen appears, click the Remove button. You will be prompted to restart the computer.

Make sure the Summagraphics Summasoft or CalComp Wintab drivers are not loaded on the system. Search your entire hard drive for the following files: WINTAB.*, TABCLASS.*, TABPORT.*, and CCNTDRV.*. The only files you need are WINTAB.EXE and WINTAB32.DLL in the ..\ustation directory. Delete any other Wintab files the search finds. If you are using Windows NT, go into the System Control Panel and select the Devices and Services icons. In the drivers list of both Devices and Services, look for the following drivers: Wintab, Wintab32, Summa*, Tabclass, Tabport and Ccntdrv. If found, set the Startup to Disabled and restart Windows NT.

Configuring the Bentley Wintab
Start the Bentley Wintab Driver (double­click the WINTAB.EXE application). At the interface screen select the appropriate tablet, size, buttons and COM port. There are quite a few formats for the Summagraphics series of tablets. See the chart below to select the correct tablet driver. If the COM ports are grayed out, there is still another driver accessing the COM port. Turn the tablet off and reboot the computer. Once windows is finished loading, turn the tablet back on and run WINTAB.EXE again. If the ports are still grayed out, double check the "Checking for other Wintab Drivers" step above.

When you have finished configuring the driver, click the OK button. The Wintab interface will close. Restart the Wintab driver (WINTAB.EXE) and the tablet should be functioning.

Note: You can either start or not start the tablet driver prior to entering MicroStation. If it is not started, it will automatically be loaded when MicroStation is started. If MicroStation starts and the cursor is gone, open a design file and type the DIG PAR command into the Command Window or Key-in browser. You should then see a little + sign; follow the prompts for the lower left and upper right corners.

Configuring the Buttons in MicroStation
To configure the cursor buttons choose Workspace > Button Assignments in MicroStation. The Button Assignments dialog box will open (see Figure 1). With the upper left cursor button in the upper section click on the button name you wish to configure (DATA, TENTATIVE, RESET, COMMAND, etc). The button name will highlight. After highlighting the appropriate button name, move your cursor to the lower section (Button Definition Area) and press the cursor button you want to assign to the action highlighted above. Place the cursor on the word "here" to make sure you're at the right location. In the top section you should see the "Invoked by" setting change.

Note: The Data button should always be invoked by the Left Button, the Reset button should be invoked by the Right button, and all the remaining buttons should be invoked by a button number. (Ex. Button 4, 5, 6, ..).

Figure 1

Note: MicroStation Version 5.0 will not display the cursor in the digitizer setup area. The cursor is still active and will function properly when tracing. Elements placed in the digitizing area will display.
