CNT-3208M-PE

Overview / Features

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.

• 8ch 32-bit up/down counter, high speed pulse input of 10MHz, and disconnection detection are available.
  • – A 32-bit up/down counter with 8 channels is mounted on one card, high speed pulse input up to 10MHz (unisolated TTL-level input, differential line receiver) is available, and disconnection detection can be performed for differential line receiver input.
    2-phase signals and 1-phase signals such as a rotary encoder or linear scale can be counted. Surge protection is realized by implementing protectors in the input circuit. In addition, 1pin/ch of control input signal is provided. It can be used as counter start/stop, preset, zero clear, general-purpose input.
• Bus master transfer function is provided.
  • – Bus master transfer makes it possible to transfer large data at a high speed without extra CPU load at a sampling rate up to 20MHz.
• Digital filter function to prevent wrong recognition of input signals due to noises is provided.
  • – Digital filter function by which noises of counter input signals (phase-A, phase-B, phase-Z) and control input signals can be prevented is equipped. Digital filter can either be not used or set within the range of 0.1μ – 1.6384msec by software.
    In addition, as all these input signals are taken into the internal counter via the digital filter, when using the digital filter, these signals are taken in with a delay of a specified duration.
• Windows compatible driver libraries are attached.
  • – Using the attached driver library API-PAC(W32) makes it possible to create applications of Windows. In addition, a diagnostic program by which the operations of hardware (interrupt, I/O address. I/O status) can be checked is provided.
• The synchronization control connectors are provided
  • – The synchronization control connectors which can make cards up to 16 pieces synchronously run are provided. In addition, the synchronous operation with CONTEC cards where a synchronization control connector is mounted can be easily realized.
• Functions and connectors are compatible with PCI compatible card CNT32-8M(PCI).
  • – The functions same with PCI compatible card CNT32-8M(PCI) are provided. In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to migrate from the existing system. Independent general-purpose timer is provided.
