CNT24-4(PCI)H 1
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.
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 supporting Win32 API
functions, such as Visual Basic or Visual C/C++.

CNT24-4(PCI)H
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).

Connecting a Board to a Connector
To input external pulse signals, use the interface connector on
the board.
Use CN1 for the photo coupler isolated input. For TTL level
input, connect CN2 to an external device by connecting the
optional cable CN2.
Matched pulse output is output from CN1. (Photo coupler

Photo coupler isolated Input Connection
Photo coupler isolated input connection with a rotary encoder
or a linear scale open collector output circuit is shown in the
Figure. The maximum input frequency is 500KHz.
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.

TTL-Level Input Connection
Use the TTL-Level Input for the connection with a rotary

maximum input frequency is 1MHz.
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 phase Z, this does not need to be connected.

CAUTION
The general input signal uses the same circuit structure.
The cable should be 1.5m or less.
To prevent malfunction caused by noise, separate the circuit
as much as possible from other signal cables and noise
sources.
One-shot Pulse Output Connection
When the count value of each channel and the user set value
match, the circuit outputs a matched signal for one shot (1
pulse). The signal output part uses the open collector method
by photo coupler insulation. As a result, an external power
supply is needed to run the board output.
