To install the driver, run dpinst.exe in the folder that contains the driver’s installation components. For more information about the Driver Package Installer, see Microsoft’s Hardware Dev Center website at https://developer.microsoft.com/en-us/windows/hardware. Opto 22 encourages OEMs that distribute software to wrap their applications and the necessary DLLs in an installer. Error Messages and Troubleshooting If one of the function calls returns false, it is an indication that an error or warning has occurred. -

Page 26: Rack Compatibility Information
Since these cards double the point capacity from their ISA cousin (the AC5), each has two 50-wire ribbon cable interfaces, referred to as bus 0 and bus 1. The PCI-AC5 and PCIe-AC5 cards include four LEDs that can be used for debugging or indicating application status. The AC5 and G4AC5 cards include one LED that flashes to indicate activity (reading from or writing to the card). -
Page 27: Pcie-Ac5
PCI-AC5 (newer version) There are two different versions of the PCI-AC5 card. The newer version shows “9278” on the white label. Power requirements for the newer card are 5.0 VDC @ 250 mA and 3.3 VDC @ 250 mA. This card is not compatible with computers that provide 5.0 VDC only. -
Page 28: Pcie-Ac5 (Older Version)
The older model has “8939” on its white label. Power requirements for the older card are 5.0 VDC at 600 mA. Again, note that LED numbering is reversed on the two cards. On this older board, bus 0 is labeled PCI-AC5-1 and bus 1 is labelled PCI-AC5-2. LED 1... -

PCI bus cycle. Reads and writes of other data sizes will result in unpredictable results. NOTE: The BIOS allocates the memory map of the PCI-AC5 well above the 1 megabyte address space of DOS architecture computers. DOS applications need a “high memory” driver or a DOS extender to access the PCI address space, as well as a DOS mode PCI BIOS extension function library to access the device’s PCI... -
