I have to read datas from some devices connected through a RS485-USB serial communication cable. The mention of "Ethernet RS-485 communication interface" confused me. To interface devices that support synchronized serial interfaces, but are not configurable like the QScreen, determine the device’s requirements for clock phase and polarity and configure the QScreen’s CPHA and CPOL accordingly. OS-MINIHUB sensors are designed to measure the surface temperature of non-reflective materials in industrial applications, from -20 to 1000°C (-4 to 1832°F). They are sealed to NEMA 4 (IP65), built from 316 stainless steel, and fully tested to industrial EMC standards. Bus Probes are a family of low-power environmental sensors with an RS485 interface. These protocols are summarized on this page, but for more information regarding their data formats and their use for simplex or multi-drop serial lines, consult Understanding Serial Communications (but keep in mind that that page is directed to the use of the UART Wildcard, so it uses different driver functions). Although the RS232 protocol specifies functions for as many as 25 pins, each communications channel requires only three for simple serial interfaces: TxD1 (transmit data), RxD1 (receive data), and DGND (digital ground). The RS232 protocol specifies the use of two separate grounds, a signal ground and a protective (or "chassis") ground.

The RS232 protocol specifies the use of two separate grounds, a signal ground and a protective (or chassis) ground. Each sensor has two mounting holes for attaching it to walls and other surfaces. The normal way to implement this is with a two wire system with differential signal levels. USB0 serial terminal to the rest of the system.

The value of each termination resistor should be equal to the cable impedance (typically, 120 ohms for twisted pairs). When PE is set (equal to one), the most-significant bit in each byte transmitted will be a parity bit that is either set or cleared by the serial port automatically in order to achieve even or odd parity. The devices use modbus RTU except for one that uses modbus ASCII. The probes communicate using the standard Modbus RTU protocol. Then you connect to the device, minimalmodbus.Instrument, and interact with it using the API.
