Appendix C:

Digital Input/Output

The Digitanl I/O on the rear panel is designed to provide

the input and output operation for the system. For sample

DIO code, see DIO folder under LEC-7110 Utility in the

Driver and Manual CD.

Install IOA3_Demo Program on Windows

Refer to Appendix A: Lanner GPIO driver installation to

install Lanner GPIO driver first and then Install IOA3_

DemoSetup.msi

Via the Command Line

Specific to the PCH chipset used or Super IO chipset, the

commands and functionality vary by product models.

For more information, refer to the README or User Guide

contained within the utility folder.

For example: Here we have IOA3 utility, to execute, follow

the command description below:

The IOA3 utility for Digital Input/

Output-------------------------------------

The IOA3 device utility (ioa3.exe) Usage:

IOA3 COM3 GET VariableName

IOA3 COM3 SET VariableName value

IOA3 COM3 “get output_state” (get the high/low state for

the digital_OUT ports)

“set output_state decimal value of the port” (set

the high/low state for digital_OUT ports)

“get input_state” (get the high/low state for the

digital_IN ports)

Argument:

The decimal value of port is calculated as shown in the

following table:

For instance, to set the output state to DO3, DO2, DO1,

DO0=1 1 1 1, type:

IOA3 COM3 set output_state 15

Likewise, to get the output state of DO3, DO2, DO1, DO0:

IOA3 COM3 get output_state
