Contec CNT24-4H Quick Start Manual

4Ch 24Bit Up/Down Counter Board for PCI
CNT24-4(PCI)H
* Specifications, color and design of the products are subject to
change without notice.
Features
It is equipped with four channels of 24-bit up/down counters.
The board can count two-phase signals, which can be outputs
of some rotary encoders and linear scales
You can select either a photo coupler isolated input or a
TTL-level input for each channel by software command.
Each channel can generate an interrupt request signal and a
one-pulse output signal when the count data matches a
pre-specified value.
The board is equipped with a programmable timer to allow
interrupts to be generated periodically according to a specified
timer value.
Each Channel is equipped with a general-purpose input signal
(both photo coupler and TTL-level).

CNT24-4(PCI)H
This product is a PCI bus-compliant interface board that counts
input pulse signals from external devices.
This product has four channels of 24-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 inputting interface is photo coupler isolated or
TTL-level input.
Using the bundled driver library [API-PAC(W32)], you can
create Windows application software for this board in your
favorite programming language
functions, such as Visual Basic or Visual C/C++.
