This product is a PCI-compliant interface board that inputs and counts pulse signals from an external device. The board has eight channels of 32-bit up/down counters, allowing external devices such as a rotary encoder and a linear scale to be connected. Given below are examples of using the board for “detecting a position of the table of a machine tool” and “detecting a change in weight”. The pulse signal incoming interface is differential line receiver input or TTL level -compatible input that can receive pulse signals at high speed. When run with the dedicated support software, the application for this board can transfer data between the board and the PC at high speed using PCI bus mastering. Windows driver is supported with this product.
