The RS485 interface allows the creation of multi-point networks. Combined with the right cables, they are going to guarantee the creation of stable and functional RS485 networks. Usually a RS232 - RS485 converter is the preferred way to establish multi-point networks when working with RS232 devices. This way you can extend the RS422 signal for up to 4000 feet. Using the Solis Data Logging Stick, which uses WiFi to communicate, we were able to set up the inverter to send data to the remote soliscloud service, but we could not find any way to get capture data apart from scraping the basic status page built into the WiFi adapter which only gave watts being produced and daily output. So in order to transfer data from a RS232 serial interface engineers need a converter to be able to connect to a RS485 or RS422 interface. It is essentially a form of serial communication. The Alpha Wire range of industrial automation cable combines quality and reliability with high performance to meet the requirements of major automation communication architectures. If handshaking is not necessary, an ordinary 4 wire telephone cable could be used, provided that the pins are cross-connected as shown in the picture below.

The ideal RS485 network requires a dedicated wire for ground. RS485 communication is well-suited for robust and noise-resistant data transfer applications, making it ideal for environments with electrical interference or long cable runs. RS485 cables are commonly used in various applications such as industrial automation, building management systems, and other scenarios where reliable and noise-resistant communication is essential. The versatility of rs485 to USB cable extends to various industries, including manufacturing, HVAC (heating, ventilation, and air conditioning) systems, and security systems. Used by the CAN based Fieldbus systems, other open Fieldbus systems, PLC and DCS systems. A cable for use with RS-485 based systems. Moreover, RS485 cables are often utilized in systems that require multidrop configurations, where multiple devices share the same communication bus. One common type of rs 485 communication cable is the twisted pair cable. Category 5 (Cat 5, Cat 5e, and Cat 6) cables are the most common Ethernet cables in use today. No matter the devices, it is always good on real site installation to use a shielded cable, with 18-22AWG wiring and the shield connected ONLY to one end of the line.


In addition to the serpentine pair configuration, STP cables feature a metallic shield surrounding the conductors. Another type is the shielded twisted pair (STP) cable. 989227-01M. Host-Master/Master-Master Controller Cable. 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 communications port also contains pins for the bi-directional encoder bus. This MJ20-PRG module clicks in the PLC and provides one RJ11 socket for serial communications with a PC. Depends what you mean by a serial cable - Fibre, Ethernet, RS232, RS485, RS422, USB, HDMI, SMPTE292 are all examples of serial communications media. Red Lion ’s G3 HMI Series is not only the first to communicate with up to five different types of serial devices simultaneously, but lets you access, monitor and control these devices remotely - from across your network, or around the globe. The rs485 shielded cable is known for supporting multi-point communication, meaning multiple devices can be connected to the same network, facilitating versatile and complex setups.


The layout for this cable is shown below. To prevent noise to interfere with the communications, often twisted pair cable is used. The cable to be used is a shielded twisted pair (telephone type). Xwire protocol over RS485 will allow cable runs of up to 1km - with suitable cable and grounding precautions- and up to 32 devices. Bus Probes can be configured and tested using our web-based test app (you will need to connect the probes to your PC or Android smartphone via our Web485 board). Both will work with RJ11 connectors and CBL03 cables. GT8E-3S-HU (Hirose) Connectors. CAN Communication between master and host. Laureate meters are modular with a middle slot reserved for a communication board, as illustrated in our Laureates Overview web page. I plugged the male-male adapter to the cable and touched the middle pin again, and I could see garbage data again. I inserted a metal piece in the middle pin of the cable (the TX) and I could see garbage data showing on the screen (sometimes!). One key feature is its differential signaling method, which involves transmitting data using two wires with opposite voltage polarities. The adapter comes standard with a 10-foot power cable and two parallel 4 pin Molex RS-485 connectors.
