This application showcases the analog and digital I/O features supported by the Remote IO Platform without using any industrial protocols. The platform communicates with a PC-based FreeMASTER application via NETC over ethernet.

• Signal generator
• MCU Digital Input pin control
• MCU Digital Output pin control
• AFE Digital I/Os control
• External Voltage Signal Measurement (HVSIG)
• Current Measurement
• Temperature Measurement
• Internal Voltage References measurement (LVSIG)
• Voltage Calibration
• Resistance Calibration

The application comes pre-programmed into the Remote IO Platform and is part of the Out-of-Box Experience.

This README contains simplified information. When using the Remote IO Platform for the first time after receiving the package, it is enough to follow the Getting Started Guide. For a comprehensive document with complete instructions, please refer to the User Guide.
