In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

One of the main benefits of RS485 is that you can put multiple devices on a single link. This is a pleasant difference from logic-level UART or RS232, especially for our sensor and other smart ...

and other Sealevel RS-485 serialdevices. The compact device works with both two-wire and four-wire RS-485networks and can be secured to the serial port with a pair of thumbscrews toprevent accidental ...

This allows RS-485 to implement multipoint linear bus topologies using only two wires. The linear bus topology is often based in a master-slave arrangement, where one device (the master device ...

The adapter circuit consists of two devices (Fig. 1). The RS-485 receiver, IC1a, is always enabled. It senses the Tx output of the PTP slave board, drives the timer (IC2), and enables the RS-485 ...

Robustness and reliability have made RS-485 an industrial workhorse. A minimum differential signal swing of 1.5V and reliable operation over common-mode voltages ranging from -7V to +12V have ...

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 ...

Analog Devices, Inc. (ADI) has introduced the ADM2867E series of reinforced iCoupler® isolated RS485 + integrated isolated dc-to-dc converters. These new parts provide low radiated emissions and ...

For serial port connections, RS-232, RS-422 and RS-485 devices are by no means common but still are in place for line-of-business solutions that may interface to non-computer systems. A number of ...
