RS485 cable length can be as long as 1.2 km, while RS232 only about 25 meters. Capabilities are used in the converter system made according to the following statement: monitoring parameters NCP series controllers, Modbus TCP network, handling controls: MN300, MN440, MN500, MN620, and heat meters - Mbus, the possibility of a software change controls, administration of the converter through a local or external PC terminal (TELNET), downloading and saving configuration files and files with FTP-client data (data downloaded, read and written by the application visualization once a day - which ensures the continuity of their records in the form of graphs), data storage (512 kB RAM with battery backup - data are recorded every 10 min, for 72 hrs.).Control and monitoring heat in Kolobrzeg installed by a company PUP SPIN SA in cooperation with the company TechBase Sp. The host software should attempt to connect to the device's IP and port to verify normal connectivity.

I tried connecting it directly to the computer either with a normal network cable or with a crossover cable but the web page doesn't open. To connect an RS485 device or RS485 network to any PC or controller, the PC or the controller should provide RS485 interface also. On the other side we also have converter RS232 - RS485 ATC - 108N, via the RS232 port is connected to cash or other device with RS232 port. If your PC or controller only has RS232 port then you need an RS232 to RS485 converter or adapter for your PC or controller. The circuit uses optical isolation (opto-coupler) to isolate your RS232 port from the RS485 cables. RS485 is simpler because it uses only two wire (or a single pair) to carry out the data in bidirectional manner, using RS232, we need 3 wires at minimum to carry the data bidirectionally. In a single phase system, analog and digital instruments are selected to measure voltage, current, frequency, and power factor. A single complex experiment or several individual experiments using multiple sensors can easily be monitored given the Brainchild's capability to record real-time inputs during one session. Able to handle multiple inputs, the datalogger provides useful information for experiments involving the heating of various liquids at a variety of volumes.

When you scan the bar code, the information actually gets sent on a 485 transceiver through a long cable to a PC somewhere within the store. Users now have the ability to monitor their live data and store all the information on the Brainchild itself or on a connected PC. They can easily update one PC, which will take care of all prices to the store. Xwire protocol over RS485 will allow cable runs of up to 1km - with suitable cable and grounding precautions- and up to 32 devices. 1. Connect the RS485 and your PC/Laptop through a LAN cable. A RS485 bus consists of one master and multiple slaves. RS485 master is the Master Brick which has a USB, Ethernet or WIFI connection to the PC running brickd. All the other Master Bricks with RS485 Extension must not have a USB, Ethernet or WIFI connection (they can use a USB Power Supply). A current transformer suitable for the application must therefore be selected. In multifunction instruments, not only the cables connected to the measurement, but also the RS485 serial port and the analog and digital inputs and outputs must be wired.

Use a 485 to USB serial cable, connect it to the interface of the 485 device and the computer's USB port, assign a COM port on the computer, open serial debugging assistant software, set the serial port parameters consistently, input the corresponding COM port, and monitor the data from the 485 device. If the serial port terminal device receives data but does not respond properly, monitor the data from the serial port device. The RS232-RS485 adapter circuit diagram is show below, RS232 DB9 is used as the RS232 port, while only a terminal block is used as RS485 connector. For RS232 a crossover cable is used where pin 1 is connected with pin 6 at the other connector, pin 2 with pin 5, etc. This interconnects the transmit and receive signals of both PLCs, and also the handshaking signals DTR and DSR. Transformers can be of different types, depending on the assembly system: a through cable or a cable with a coiled primary, transformers for assembly on horizontal or vertical bars. The small PCB sensor has mounting hole which allows it to be cable tied within the internal airflow of the Generator. The Brainchild's built-in display allows teachers and students to get a clear review of all measured data on its 6.4'' VGA Color LCD displaywith flexible screen configuration.
