2. PCI-DIOxx Series Configuration
This chapter provides detailed description of PCI-DIO64xx (PCI-DIO6400, PCI-DIO6401, PCI-DIO6402
with cPCI-DIO6400) series boards. It processes digital data of 32/32 bit In/Out, 64 bit In, and 64 bit
Out according to each board and uses PCI and Compact PCI interfaces.
PCI-64xx series boards use a high reliability photo coupler to increase the reliability and execution
of signals with isolated lines, and do not require an external circuit for initial state and a separate
mechanism for interrupt. Since the main interface is designed with FPGA, it is free to enhance or
modify functions, and it can be easily upgraded according to the user's needs.
