RS422 devices. These networks are often used in a half-duplex mode, where a single master in a system sends a command to one of several "slave" devices on a network. With the introduction of "automatic" repeaters and high-impedance drivers / receivers this "limitation" can be extended to hundreds (or even thousands) of nodes on a network. USB to RS485 cable: USB to RS-485 converter is used to monitor each controller on the network using Solar Station PC software. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices.

The Modbus protocol further enables RS485 by allowing a master to send and receive data from specific sensors on the bus or to communicate with all the sensors simultaneously. Our USB development kits use GasLab® software for setup, calibration, data logging, and real-time data analysis. This cable enables RS485 communication between our EC and MX Smart Sensor boards and development kits and our free GasLab software.

Custom FTDI USB - RS485 Cable with Molex connector, fits all GasLab EC and MX Smart Sensor Boards and Development Kits. RS485 is a serial data transmission interface standard that enables communication with sensors attached to the same bus (wires). GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.

The Serial Peripheral Interface, SPI, is a fast synchronous serial interface. USB to RS 422 / 485 serial adaptor cord is a high quality industrial USB plug and play dongle designed to instantly add a RS485/RS422 port to your PC or Mac system via USB interface. They translate the bit-by-bit data on the serial cable into bytes of data that can be interpreted by the operating system or by your application program. Although many applications use RS-485 signal levels, the speed, format, and protocol of the data transmission are not specified by RS-485. The SN65HVD72 IC converts the 3.3V UART signals to RS-485 voltages allowing communication with RS-485 compatible devices over a DB9 serial cable or twisted pair cable.

In order to facilitate the configuration of computer serial interfaces of different standards, remote data communication between external devices or intelligent instruments, it is necessary to carry out standard conversion on the serial interface. It's such a successful technique that it has not been supplanted by new modern communication technologies like TCP/IP. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. The RS232 signals are represented by voltage levels with respect to a system common (power / logic ground). It is helpful for demo and testing when the power supply is not available. USB to Serial cable RS485 is the ideal solution for connecting industrial devices such as laboratory testing and measuring equipment, monitoring devices, material handling equipment, and many more devices where mission critical applications are required. Working modes: asynchronous; point-to-point or point-to-multipoint; 2-line RS485 half duplex and 4-line RS422 full duplex. Note that the local and the remote must share a common ground, so a minimum of 3 wires are required for full duplex RS232 communications: a transmit wire, a receive wire, and a common ground. Newer protocols include the full duplex RS422 and the half duplex RS485 protocols, each of which drives differential 0 to 5 volt signals on the serial cable.
