These subsystems are Modems, MUXs, RF up converters, RF down converters and more. RS485 to Ethernet Converters connect devices with RS485 serial interfaces to a local area network for transmission of serial data over wired or wireless Ethernet. While some RS485 to Ethernet Converters can be very simple devices, it is best practice to use one with advanced security functionality, data encryption, and user authentication to ensure network data transmissions, and access to network equipment is protected. They are designed to ensure that when you access attached devices over a network the connection operates as if you are locally connected to the RS485 port with a direct cable connection. Each E-16D monitoring system supports up to three E-RJ8-RS485 expanders, allowing for a total of 37 RJ45 RS485 sensors to be connected to the E-16D. If PT is set, all transmitted bytes with a parity bit will have an odd number of total '1' bits. The primary channel’s UART translates the bit-by-bit data on the serial cable into bytes of data that can be interpreted by the QED-Forth Kernel or by your application program. One of the application is VSAT NMS (Network Management System) where in software application running on one PC is used to monitor & control many sub systems.
AURORA, Ohio - April 30, 2020 - PRLog -- Network Technologies Inc (NTI) today announced the addition of the RJ45 RS485 Sensor Port Hub for its E-16D Large Enterprise Environment Monitoring System. We have been using Microcontroller Development Boards like Arduino, Raspberry Pi, NodeMCU, ESP8266, MSP430, etc. for a long time now in our small projects where most of the times distance between the sensors and board is not more than few centimeters at max and at these distances, the communication between the different sensor modules, relays, actuators, and controllers can be easily done over simple jumper wires without us being worried about the signal distortion in the medium and the Electrical noises creeping into it. There is also the GSM version; especially useful when only one sensor is needed in a remote location where other types of transmission cannot be used. But there are some limitations to it as it cannot support multiple slaves and multiple masters and the maximum data frame is limited to 9 bits. If you need to control multiple devices, the RS485 will be a better pick as well.

This FTDI converter cable provides a fast, simple way to connect devices with an RS485 interface to USB. FTDI USB to RS485 Serial UART Converter Cable incorporates FTDI's FT232RQ USB to serial UART interface IC, which handles all the USB signaling and protocols. Figure-1 depicts pin configurations of RS485 interface in a 9 pin DB9 connector. As shown in the pin diagram, RS485 has all the signals in differential configurations. However, if you require a higher data transfer speed over a longer distance, RS485 will work better. However, you can make the representative inverter in each block report the occurrence of a problem in the block. These characteristics make RS-485 useful in industrial control systems and similar applications. The RS-485 port on the RS485 Pi can be accessed through the male DB9 socket or the solder points on the PCB. We will send some data from the transmitter side over the cable from the Nano which is converted to RS485 signals via MAX RS485 Module working in Master Mode. In a multi drop configuration about 32 devices can be connected with 1 master controlling device.
Since it uses a differential line over twisted pair (like EIA-422), it can span relatively large distances (up to 4000 feet or just over 1200 metres). When communicating at high data rates, or over long distances in real world environments, single-ended methods are often inadequate. Rather, it relies on software handshaking via transmission of XON/XOFF characters to coordinate data transfer and ensure that information is not lost when one of the communicating parties is busy. By connecting pairs of these handshaking signals together, the terminal or PC can be made to think that the PDQ Board is always ready to send and receive data. This can vary greatly depending upon the device. This device stores the temperature in Centigrade, but as an integer 100x than the actual value. It may be that only the byte sent from the master to the slave is meaningful; nevertheless, each device simultaneously transmits and receives one byte. You can use one or both of the PDQ Board’s RS485 links to create such a multi-drop serial network.
