Connect the tester and pickup device with the audio cable. 3.This monitor also Support Audio testing:Test the audio input from pickup devices. It is important to know how to wire devices on an RS485 network, especially when a non opto-isolated device is present. The RS485 network is wrongly referred to as a "2 wires plus shield" network. End of line termination resistor (120 ohm 1/4 watt) to be installed at both ends of network. 2 Alphanumeric LCD, and MAX485 UART to RS485 converter IC connected to each end of an Ethernet Cat-6E cable via an RJ45 connector. One to two logic-high stop bits mark the end of a character. RTU (Remote Terminal Unit) mode transmits 8-bit messages as two 4-bit hexadecimal characters in a continuous stream. RS485-LN ships with two DIN rail holders, a LoRa antenna, and a programming cable. The device ships with an Ethernet RS-485 communication interface as well as a RS-485 to USB cable, which is said to be able to communicate with a PC using proprietary Windows based software (and driver, I think).

Entire USB protocol handled by the electronics in the cable. Sig- lines are twisted as twisting nullify the effect of electromagnetic noise induced in a cable and provide a much better immunity against the noise which allows the RS485 to transmit the data up to 1200m of range. The main reason behind using these Ethernet Cables over normal wires is that they provide much better protection against noise creeping in and distortion of the signal over high distances.

The QScreen Controller’s kernel software contains a complete set of high level driver routines for the Serial2 port, and these functions are summarized in the Control-C Glossary. 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). The RS-485 port is connected to the UART port on the Raspberry Pi using a SN65HVD72 interface. 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. The device that initiates a data transfer is the master, and all other devices on the network are slaves.

The words port and channel are used interchangeably to refer to a serial communications link. We can gain insight into the operation of the RS232 protocol by examining the signal connections used for the primary serial port in Table 9 6. The transmit and receive data signals carry the messages being communicated between the QScreen Controller and the PC or terminal. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. Our USB development kits use GasLab® software for setup, calibration, data logging, and real-time data analysis. Custom FTDI USB - RS485 Cable with Molex connector, fits all GasLab EC and MX Smart Sensor Boards and Development Kits. 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.
