High-speed up/down counter board for PCI Express

It is an interface board 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.

	8 chanels 32 bits up/down counter was equipped on one board, The high-speed pulse input (a Non-isolated TTL level, a differential) to 10MHz at the maximum is possible and can perform the disconnection detection when the differential input. It can count two-phase signal and a single-phase alternating current signal. It implements a protection element in an input circuit and realize surge protection. In addition, it carries one point/ch control input signal, and can use it as counter start/stops,pre-sets zero clear, and the general-purpose input.
	It can forward large-capacity data without hanging load to CPU by Bus master transfer.
	The digital filter is equipped which can prevent a noise of a counter input signal (A-phase, B-phase, Z-phase) and a control input signal. A digital filter can set to unused or in a range of 0.1uSec - 1.6384mSec by software. In addition, so that all these input signals go along a digital filter, and they are captured inside counter, When used a digital filter, they are captured by a delay for setting time.
	It carries the synchronization control connector which can let the board of 16 pieces at the maximum run in the same period. In addition, It can easily realize movement in the same period with a board made in us which carried a synchronization control connector.
	It is equipped with the function that is similar to PCI board CNT32-8M(PCI). Furthermore, To be compatible with of connector shape and signal placement, a shift from a existingl system is easy.
	In the input circuit, connects varistor for protection from a surge. In addition, it is equipped with the timer which can generate interrupt by the period when appointed it. It can perform timer setting in a range of 1 - 6553msec(1msec unit).
