It is an interface card for PCI Express bus conformity. it can count a pulse signal from an outside device input. 8ch is equipped with 32 bits up/down counter, and high-speed data transmission is possible by the high-speed pulse input (a non-isolation Time To Live level, a differential) to 10MHz at the maximum by Bus master transfer function. In addition, It can count two phase signals, such as a rotary encoder or linear scales, and a single-phase alternating current signal. It attaches a Windows version driver library and can make the application that can made use of a characteristic of our hardware in.
