App note: Design considerations for a harsh industrial environment

Saturday, March 9th, 2019

This article discusses factors that influence the robustness of a circuit in a harsh environment, like you would find for industrial applications. The topics covered include ways to handle voltage transients and to protect against electrostatic discharge (ESD) and faults. Link here Semiconductor (IC) robustness—what is the operating temperature range? How...

isoUSBRS422, an open source isolated USB-RS422/RS485 converter board

Thursday, December 17th, 2015

Alper Yazar has posted an update on his open source isoUSBRS422 project we covered previously: As I said, basically it is an USB ↔ RS-422/RS-485 converter board. It can be used to communicate devices with RS-422/RS-485 interface by using a USB port of PC. Also, ground of USB port is...

App note: Reference of Maxim RS-485 chips

Saturday, December 24th, 2011

Maxim describes the features of their RS-485 line of transceivers. It's important to chose transceivers for RS-485 communication that fall within the specifications of your network. The RS-485 standard is used in many applications, such as professional stage lighting. There is no clock signal so all the devices have to...
