This chapter provides information you should know before using the product.
About the Board
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 line receiver input 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 supporting Win32 API functions, such as Visual Basic
or Visual C/C++.

Features
-
This board is a PCI-compliant interface board for counting input pulse signals.
-
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 line-receiver 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 line-receiver and TTL-level).
-
Protective devices are equipped for line-receiver inputs.
