1. Remove the computer cover Carefully install the card in an available 5V or 3 3V PCI expansion slot you may need to remove a backplate first Inspect for proper fit of the card and tighten screws Make sure that the card mounting bracket is properly screwed into place and that there is a positive chassis ground Install an I O cable onto the card s bracket mounted connector Replace the computer cover and turn ON the computer which should auto detect the card depending on the operating system and automatically finish installing the drivers Run PClfind exe to complete installing the card into the registry for Windows only and to determine the assigned resources Run one of the provided sample programs that was copied to the newly created card directory from the CD to test and validate your installation The base address assigned by BIOS or the operating system can change each time new hardware is installed into or removed from the computer Please recheck PCIFind or Device Manager if the hardware configuration is changed Software you write can automatically determine the base address of the card using a variety of methods depending on the operating system In DOS the PCNSOURCE directory shows the BIOS calls used to determine the address and IRQ assigned to installed PCI devices In Windows the Windows sample programs demonstrate querying the registry entries created by PCIFind and NTIOPCI SYS during boot up to determine this same in2. down the card s response to eliminate noise spikes on DC inputs in industrial environments or to convert sinusoidal AC inputs The 5 mSec filter can be enabled for all inputs 0 15 by a software read from base address 3 or disabled by a write of any value to base address 3 The filters for inputs 0 7 can be programmed individually by a write to base address 7 when the previous global enable command has not been given a value of one in the corresponding bit location activates the filter and a value of zero disables that filter The status of filters 0 7 can be read back from base address 7 INTERRUPTS The card supports interrupts The interrupt level is assigned by the BIOS or plug and play operating system The assigned interrupt level can be viewed when PCIFind EXE is run see chapter 3 The card s interrupt capability makes it is unnecessary to continuously poll inputs by reading at base address 1 and 5 to detect when an input state has changed To enable interrupts read from base address 2 To disable interrupts write any value to base address 2 To clear an interrupt write any value to base address 1 The user must include the clear instruction in the interrupt service routine software For shared interrupt applications the card has an IRO status byte that can be read from base address 6 Bits O and 1 set indicate interrupts are enabled bit 2 set indicates an IRQ has been generated bits 3 thru 7 will always read 0 12 Manual PCI IDIO
