ADU  Series - USB Data Acquisition Interface SDK

ADU Device Pipe

The AduHid DLL provides a pipe to transmit commands and responses between an application program and the ADU device.

A command instructs the ADU device to perform some action. For example the SK1 command causes the ADU device to close relay 1.

Some commands generate responses that are returned to the PC. The responses travel on the ADU Device pipe. For example the RPK1 command causes the ADU device to return the status of relay 1.

An application opens an ADU Device Pipe with the OpenAduDevice function.

Commands are written to the device pipe with WriteAduDevice.

Responses are read from the device pipe with ReadAduDevice.

When finished close the device pipe with CloseAduDevice.


Note: all device pipe functions include "AduDevice" in their name
