This is an PCI bus compliant interface board for counting the pulses input from the external device. The board has four channels of 32-bit up/down counters, allowing external devices such as a rotary encoder and a linear scale to be connected. The pulse signal inputting interface is unisolated LVTTL-level input that can input pulse signals at high speed. The application for this board can transfer data between the board and the PC at high speed using PCI bus mastering. With the Windows version driver (API-PAC(W32)).
