API Codec Quick Start Guide

What is the API Codec? If you are working with TCP/IP or Wireless communications, you might want to consider using the API Codec to handle all communication functions.  The API Codec will “wrap” standard commands with a Header, Byte Counter, and a Checksum, which eliminates the need for timeout command processing (the standard method of communications which stalls processing of commands). he API Codec is a faster, more reliable method of communicating to NCD devices, particularly when working with network- or wireless-based devices.  The API Codec makes communications more resilient to errors and eliminates timeout requirements of standard communication methods.

I2C Communications Quick Start Guide

Introduction I2C communications is a integral part of communicating to sensors and peripheral devices.  Learning to implement I2C Communications in combination with NCD devices allows users to expand their relay controllers into sensor monitoring and control applications.  One of the greatest benefits of I2C communications is the simple protocol for talking to external devices.  Since many manufacturers generate sensors and chips that support I2C communications, it is possible to monitor and control thousands of different external devices by simply learning a few simple commands. NCD is manufacturing and developing many controllers that support I2C communications.  Most notably, Fusion series controllers all include at
