General Description

Diolan USB-IO Interface Adapter adds digital and analog IO capabilities to any computer with USB port. Any of 24 IO pins can be configured to accept inputs, to drive outputs, to send continuous PWM signals or to send single pulses.

You can configure pins in input mode to notify PC software when the input signal level is changed. To avoid contact bounce, signal level is accepted after it has been stable for a predefined period of time.

In PWM mode each contact can be independently configured to send square waves with predefined high and low signal periods. Periods can vary from 1ms up to 65 seconds.

Flexible API allows software development to use any programming language. Even if you don't want to deal with programming you can still benefit from GPIO-24 adapter. We offer a lot of ready to use software applications for this USB-IO Interface Adapter.

Diolan engineers are constantly working on additional functionality for USB-IO adapter. Forthcoming updates can be easily installed at the previously ordered units. If you want any specific GPIO-24 adapters functionality, we would be happy to implement customized SW at quite a competitive price. In case it is a common change that may be helpful for other customers, we might do it for free.
