In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

Ratified in the early 80's as a new balanced transmission standard, RS-485 has emerged as the industry's seemingly eternal interface workhorse. Much literature has been written on the subject since, ...

As a standard for industrial communications, the RS-485 differential interface is useful in communicating long distances where immunity to common-mode noise is an important requirement. RS-485 ports ...

RS-232 was the PC serial communications standard for many years. Hardware and software support for this simple, yet effective, interface was included on every PC made until it was eventually replaced ...
