This technical tip post covers the history and challenges of connecting RS-232 serial devices together.

The nice thing about standards is that there are so many to choose from. Like every profession, industrial automation has a veritable cornucopia of standards we need to be aware of. RS-232 is no different or special in that regard.

Let's take a look at the history of this hardware communication standard and use that as a springboard. We'll take a look at how modern microprocessor technology can be adapted to this very commonly used data communication standard in the industrial automation world.

Learn how to set up, install, and communicate using a groov EPIC serial I/O module.

Many industrial automation applications require communication between the controller and multiple serial devices. The GRV-CSERI-4 module provides four independent and isolated serial ports for this purpose. Each port is software configurable to communicate with RS-232 or RS-485 (half duplex or full duplex) serial devices.
