  • The State of Industrial Serial Communication
    RS-232, RS-422, and RS-485 have a long history in industrial automation. One of Moxa's most experienced engineers discusses the state of these legacy communication standards and how they are integrated in today's industrial communication equipment. Thoughts on industrial serial communication
