Page 13: Quick Start
ICP DAS provides a range of demo programs for different platforms that can be used to verify the functions of the I-8026W. The source code contained in these programs can also be reused in your own custom programs if needed. The executable file, can be used to retrieve the basic configuration information related to the module and to verify the AI read functions. -
Page 14: Api Functions
Writes the Digital Output value to the I-8026W module. i8026W_WriteDOBit Sets a specific Digital Output channel of the I-8026W module to ON or OFF. i8026W_ReadDIO Reads the Digital Input and Digital Output value from the I-8026W module. Reads a calibrated Analog Input value from a single specified channel in i8026W_ReadAI float format. -
Page 15: I8026W_Init
Before executing any functions on the I-8026W, the i8026W_Init function needs be called once for each I-8026W module inserted in the controller unit. For example, if there are two or more I-8026W modules inserted in the controller, the i8026W_Init function must be individually called for each I-8026W module by including the number of the slot where the I-8026W module is inserted. -

Page 32: Service Request Requirements
4.1. Service Request Requirements If you are using a stable signal source, such as a battery, to output a signal to the I-8026W module and are receiving incorrect or unstable data, prepare the following three items and e-mail them to service@icpdas.com. -
Page 33: What To Do When The Data Read From The I-8026W Seems Unstable
A floating signal source that is not referenced to a system ground point (earth or building ground) Because of the nature of the high speed data acquisition function on the I-8026W module, any noise coupled to a signal, or any change in voltage on an unstable source, is also captured. In this situation, signal filtering or isolation should be considered in order to enhance the quality of the signal. - Page 34 There was a gain index error. gain numbers should be in the range of 0 to 4.
