Industrial Networking: Introduction to Networking

Doug Bell introduces Chris Harris. Networks communicate in several ways including by wire, wireless, and fiber optics. Various standards such as RS-232, RS-422, RS-485 and Ethernet come with the particular device being...

Industrial Networking: Basics of RS-232

The RS-232 standard allows for communication between two devices in either a master-slave or master-master configuration. A master-master configuration does not require the cables to be changed however the hardware needs to...

Industrial Networking: RS-232 Media and Hardware

All types of connectors are found with RS-232 with no set standard, zip links are a solution especially in long distance (up to 50 feet) applications. DTE and DCE devices require different wiring configurations. The device...

Industrial Networking: Networking Protocol Basics

A compatible wiring scheme does not mean two devices can communication with each other, they need the same language. In a network, there must be a device that produces a signal for the network to work, cannot have two slave...

Industrial Networking: Basics of RS-422

The RS-422 standard allows use with up to 11 devices and 4000 feet of wire. The standard is commonly confused with RS-485 and can even work with RS-485 devices. RS-422 is not widely supported. Long-time automation trainer Doug...
