Ver.1.10 CNT32-4MT(LPCI) 1 4ch 32Bit High-Speed Up/Down Counter Board for Low Profile PCI (TTL Input) CNT32-4MT(LPCI) * Specifications, color and design of the products are subject to change without notice. This is a PCI bus compliant interface board for counting the pulses input from the external device. The board supports a low-profile PC I slot and, if replaced with the supplied bracket, supports a PCI slot, too. 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. Given below are examples of using the board for “detecting a posi tion of the table of a machine tool” and “detecting a change in weight”. 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. <Example > Linear ScaleCNT32-4MT(LPCI) Encoder CNT32-4MT(LPCI) - Detecting a position of the table of a machine tool Processing thing Tool Power supplyRelayBOX - Detecting a change in weight Power supply Rack 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 wi thout intervention from the CPU. Can generate an interrupt, issuing an external signal, or presetting/zero-clearing the c ount value when it matches an arbitrary predefined value. Support for both of low-profile and standard PCI slots (interchangeable with a bundled bracket). < 1 / 2 > Item Specification Input Counter Channel count 4 channels Count system Up/down counting (2-phase/Single-phase/Single-phase Input with Gate Control Attached) Max. count FFFFFFFFh(binary data, 32Bit) Input type Unisolated LVTTL level input Input signal Phase-A/UP 1 x 4 channels Phase-B/DOWN 1 x 4 channels Phase-Z/CLR 1 x 4 channels Response frequency 10MHz 50% duty Digital filter 0.1 μsec - 1.6384msec or not used (can be independently set for each channel.)

Driver Library API-PAC(W32) (Bundled) API-PAC(W32) is the library software that provides the commands for CONTEC hardware products in the form of Windows standard Win32 API functions (DLL). It makes it easy to create high-speed application software taking advantage of the CONTEC hardware using various programming languages that support Win32 API functions, such as Visual Basic and Visual C/C++. It can also be used by the installed diagnosis program to check hardware operations. CONTEC provides download services to supply the updated drivers and differential files.

You can connect to a rotary encoder or linear scale with a TTL level output circuit, or to an open-collector output circuit. The signal must be an LVTTL level input and can be up to 10MHz. As pull-up resisters are provided on the board, connect the pull-up voltage (3.3V to 5.5V max.) to the pull-up pins if connecting to an open collector output circuit/TTL-level output circuit. (If using 3.3V, connect to the VCC pin on the board.) Not connecting the pull-up voltage may affect the counter input channel left unconnected. For a two-phase input, connect both phase A and phase B. For a single phase input, connect to either phase A or phase B. If not using the Z phase, this does not need to be connected. Remarks The pull-up pins are PUP1 (pin 32 *1) for the counter input signal and PUP2 (pin 66 *1) for the control input signal. PUP1 (pin 32): Pull-up for A, B, and Z phase input signal PUP2 (pin 66): Pull-up for the control input signals and for the sampling input signals (DI0, DI1, DI2, DI3, CLKIN, STARTIN, STOPIN). *1 Connector pin number on the board.

To prevent noise from causing a malfunction, arrange the connection cable as away from any other signal conductor or noise source as possible. Using the On- Board Connectors How to Connect the Counter Input Signal

Ver.1.10 CNT32-4MT(LPCI) 4 Connection of a control input The control input signals consis t of one pin per channel that can be selected as the channel's counter start/stop or preset, and one pin per board that can be used as the start, stop, and clock for sampling. The signals are LVTTL-level inputs. As pull-up resisters (10KΩ) are provided on the board, connect the pull-up voltage (3.0V to 5.5V max.) to the pull-up pins if connecting to an open collector output circuit/TTL-level output circuit. (If using 3.3V, connect to the VCC pin on the board.) Not connecting the pull-up voltage may affect the control input pin left unconnected. Remarks The pull-up pins are PUP1 (pin 32 *1) for the counter input signal and PUP2 (pin 66 *1) for the control input signal. PUP1 (pin 32): Pull-up for A, B, and Z phase input signal PUP2 (pin 66): Pull-up for the control input signals and for the sampling input signals (DI0, DI1, DI2, DI3, CLKIN, STARTIN, STOPIN). *1 Connector pin number on the board.

CAUTION The connection cable length should be within 1.5 m. To prevent noise from causing a malfunction, arrange the connection cable as away from any other signal conductor or noise source as possible. External sampling clock signal (EXTCLK) Pin used to input the external pacer clock. The maximum frequency is 10MHz. If the external clock input is selected as the sampling clock, sampling occurs on the falling edge of the signal. EXTCLK tPWH tPWH : High-level clock pulse width 50nsec (Min.) tPWL : Low-level clock pulse width 50nsec (Min.) tPWL Other control input signals (DI0 to DI3, EXTSTART, EXTSTOP) These signals are TTL-level compatible and the trigger edge is software-programmable at either the rising or falling edge. High- and low-level hold times of at least 50 nsec are required to detect an edge of the signal. tHIH tHIH : High-level hold time 50nsec (Min.) tHIL : Low-level hold time 50nsec (Min.) tHIL tHIH Connection of a control output This outputs a general-purpose output signal (level output) or a one-shot pulse output to indicate a hardware event such as a count match. The signal is an LVTTL level output and can be set to positive or negative logic by software.
