| DAQ Card Software 004 Q. How to use two or more cards in the same time without calling ActiveBoard() function again and again?
You can record the Base-Address
of all cards first, and then calling I/O functions directly
without ActiveBoard()function
calls anymore. For example, to use ISO-P64 under Windows 2000: // Get address first
1. ISO_ActiveBoard(0)
2. ISO_GetConfigAddress(&wBase0, &BoardNo) 3. ISO_ActiveBoard(1) 4. ISO_GetConfigAddress(&wBase1,&BoardNo) // I/O directly
5. ISO_InputByte(wBase0+n)
6.
ISO_InputByte(wBase1+n)
