Abstract: The proper method of wiring an RS-485 network is described, with recommendations for twisted-pair cabling and correctly locating termination resistors. Received waveforms are shown for examples of proper and improper cable termination. Configurations are shown for a simple, single-transmitter/multiple receiver network through multiple transceiver to multibranched circuits. This application note provides basic guidelines for … More Guidelines for Proper Wiring of an RS-485 (TIA/EIA-485-A) Network

Supervisory Control and Data Acquisition (SCADA) is a system that uses coded signals over telecommunications lines to control remote equipment, using typically, a single communication channel for each remote station. SCADA was first launched in the 1960s, over the years it has had significant developments and used extensively by numerous industries that have required the … More Supervisory Control and Data Acquisition (SCADA)

Developers have long struggled with keeping testing information safe when working with protected information. While it is clear of the importance of keeping security such as surveillance or monitoring equipment functional, there are also scenarios where the actual data itself is the target. Businesses dealing in protected consumer information need to be especially vigilant when … More Networking Security and Compliance – Doing Business With Protected Information

Air Traffic Controllers hold an enormously stressful position. They make sure airplanes can safely arrive at their destinations. Operating from large control towers, they sit surrounded by equipment that must work well in order for their job to succeed. Over the last few years, there have been multiple instances of hackers attempting and in some … More Air Traffic Controllers Need Dependable Equipment To Help Defend Against Hackers

USB to RS485 converters are usually utilized to allow personal computers to get in touch with RS485-compliant tools on commercial automation networks, such as automation, video surveillance electronic cameras and also door protection card users. Although the RS485 spec recommends a default geography based upon ‘master-slave’ point-to-point or multi-drop configurations, the use of multiport repeaters … More USB to RS485 Converters – Types and Uses

The latest craze in the Web is making use of an Ethernet cable television in order to link your computer to the Internet. It is much faster compared to the old phone lines that were made use of for the past few years. Nonetheless, many people are puzzled regarding merely how they could utilize an … More USB to Ethernet Conectivity

Serial communication was originally developed for the teletype (nickname for a teletypewriter and trademark of the Teletype Corporation USA), an electro-mechanical marvel that emerged in the 1920’s for transmitting messages from one point to another. Some even used punched paper tape so you could relay information output from one teletype and feed the strip into … More RS232 and Mobile Data Systems

RS485 is an electric interface specification still commonly made use of by commercial automation tools such as sensors, electric motor managers, temperature level controllers and control valves that communicate real-time, deterministic data across bus-based networks. Although newer tools that utilize Ethernet-based network procedures are gradually changing it, there continues to be a very large mounted … More Benefits of Using RS232 to RS485 Converters

With each passing day it seems yet another globally recognised company is falling victim to a security breech. Customer data, confidential information and embarrassing leaked internal communications can bring a business to its knees from a public relations standpoint. Even more concerning is the possibility of hackers attacking a network infrastructure and halting business altogether. … More Security: Why Dependable Equipment Helps Keep Your Information And Employees Safe
