Question : How can I use two plug-in boards with DriverLINX in the same application?
Answer: DriverLINX supports the use of multiple boards from the same application. The key to doing so successfully is to have a unique Service Request for each board.
If using the ActiveX API (typically from Delphi or Visual Basic) place a DriverLINXSR control onto the form for each board that you use. If using the DLL API (typically C/C++ languages), declare a variable of the DL_ServiceRequest type for each board.
Another important piece of information for C/C++ users, is to make use of the SelectDriverLINX(instanceHandle) function each time you switch between the use of each board. For example, suppose you have a KPCI-3101 and a KPCI-PIO24 board. Before doing any digital I/O with the KPCI-PIO24, call the SelectDriverLINX with the instance handle returned when you opened the kpcipio driver for that board. Then, before starting any analog I/O task with the KPCI-3101, again call SelectDriverLINX but with the instance handle returned when you opened the kpci3100 driver.
