1. About the Counter Input Driver

Counter input driver is composed of API-CNT(WDM) and API-CNT(98/PC).
API-CNT(WDM) is new driver software for executing counter input on Windows. It was developed by the goal of "easy to use" and "high functionality" compared with API-CNT(98/PC) that is a earlier edition.

When you use counter input devices, you are suggested to use API-CNT(WDM), but you should pay attention to the operation environment. API-CNT(WDM) is planed to support the new OS and devices, but not support Windows NT4.0, Windows 95, ISA bus and so on. For those environment mentioned above, please use API-CNT(98/PC).
(For details, please refer to 3. Specification Comparison)

4. Features of API-CNT(WDM)

Easy-to-understanding Interface

It can be used simply and easily because of the lineup of functions classified by functionality.

A lot of sampling programs are prepared corresponding to using method.

Concealing difference between hardware functionality

The difference between hardware is concealed in the driver as possible.

The function interface is common to API of USB device.

Easy to install and set up the driver

After a device is searched out, follow the wizard direction to install the driver.
After installation, you should just make a decision of the device name in property page of device manager.

5. Q & A

Is API-CNT(WDM) compatible with API-CNT(98/PC)?
Will API-CNT(98/PC) not be sold in the future?
Can API-CNT(98/PC) be changed to API-CNT(WDM) if it is being used at present?
Can the two kinds of driver be used at the same time?

Q. Is API-CNT(WDM) compatible with API-CNT(98/PC)?

A. Both API-CNT(WDM) driver and API-CNT(98/PC) driver are not compatible each other.

Please keep on using API-CNT(98/PC) if you still use existing system.
It is suggested to use API-CNT(WDM) in which case such as developing new system and investigating the change of using board.

Q. Will API-CNT(98/PC) not be sold in the future?

A. It will be kept on selling in the future.
Please keep on using API-CNT(98/PC) if you still use existing system.

Q. Can API-CNT(98/PC) be changed to API-CNT(WDM) if it is being used at present?

A. Yes. Uninstall the present driver and install the new driver.

Q. Can API-CNT(WDM) and API-CNT(98/PC) be used at the same time?

A. No. Two kinds of driver can not be used to one board.
For example, if API-CNT(98/PC) is being used, you cannot use API-CNT(WDM) for programming to implement the specific functionality.
