概要?特點

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)).

• Can input two-phase and single-phase signals. Can input pulse signals up to 10MHz and can resolve phase differences as short as 25nsec.
• Can be converted to a differential input interface using the differential unit (CTP-4D) and connection cable (CNT-68M/50M) which are sold separately.
• One control signal input pin per channel.
• Can count values sampling at a maximum sampling rate of 20 MHz. Supporting bus mastering, enabling high-speed data transfer between the board and the PC without intervention from the CPU.
• Can generate an interrupt, issuing an external signal, or presetting/zero-clearing the count value when it matches an arbitrary predefined value.
• Support for both of low-profile and standard PCI slots (interchangeable with a bundled bracket).
