Industry 4.0 marks the fourth industrial revolution, characterized by distributed, intelligent control systems. Breaking from a past with large, centralized programmable-logic controllers, Industry ...

What is the difference between RS-422 and RS-485 and do you know when to use which one? How many devices can you connect to an RS-422 or RS-485 network? Can you mix RS-422 and RS-485 devices on the ...

Industrial data links requiring the transmission of RS-232 data over long distance, or between multiple RS-232 applications, often use RS-232-to-RS-485 converters. Despite the wide and high signal ...

Yes, you read that right: The decades-old RS-485 interface standard—the enhanced, differential, multidrop extension to the legendary, classic RS-232 interface—is alive and well. If you assume RS-485 ...

There are other RS-485/422 transceivers with inductive isolation available, but Linear Technology has taken a step forward. Its LTM2881 µModule includes its own complete, isolated dc-dc power supply, ...

Guest columnist Ian Doyle, product line manager for semiconductors at Bourns, describes how to provide suitable circuit protection for RS-485 ports. RS-485 is one of the most common interface ...

RS485 is a communication standard that should be part of the advanced hardware hacker’s arsenal; it’s not commonly encountered, but powerful exactly when you need it. It’s a physical layer interface ...

High-quality, low-capacitance data cables have impedances specific for RS-232/422 and RS-485 communication applications. High-quality, low-capacitance data cables have impedances specific for ...
