In a computer system, SCSI-2 and SCSI-3 may use this specification to implement the physical layer for data transmission between a controller and a disk drive. It works on half-duplex communication to implement the function of converting the TTL level into RS-485 level which means it can either transmit or receive at any time, not both, it can achieve a maximum transmission rate of 2.5Mbps. MAX485 transceiver draws a supply current of between 120μA and 500μA under the unloaded or fully loaded conditions when the driver is disabled. And if I do that, how can RS485 flags and RTS delays be set?

When I tried to read the registers of the meter through the software, I ran a serial port monitor software to sniff the bytes being sent and received to the meter. My question: Is it possible to send the request bytes (which were found above) to the meter and then get the answer bytes and saved them on pc? Basically, is it possible to communicate with the meter by sending the hex bytes and receiving the answer? I have a smart electricity meter that connects to the pc through RS485 serial cable.

If the bus is longer than a few meters then some kind of twisted pair cable is recommended. Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance. Without termination resistors, reflections of fast driver edges can cause multiple data edges that can cause data corruption. Finally, if this means that enabling RS485 mode is not required in this configuration, rs485 cable can the FTDI cable be bypassed entirely by using Raspberry Pi's built-in UARTs combined with a chip like ZT485EEN? I've tried using the ftdi d2xx drivers to connect to it, but so far I can't read any data and while the writes don't fail, I'm not sure they're working. Since Pi's built-in UARTs don't support the RS485 standard, I'm using the USB-RS485-WE-1800-BT FTDI cable. The SN65HVD72 IC converts the 3.3V UART port to RS485 differential voltages allowing communication with RS485 compatible devices over a twisted pair cable. 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.

I'm trying to port a program, which communicates over RS485 half-duplex UART, to Raspberry Pi. The RS485 Pi is a communication board supporting the RS-485 serial protocol, designed to work with the Raspberry Pi and other compatible single-board computers.

In contrast to RS-422, which has a driver circuit which cannot be switched off, RS-485 drivers use three-state logic allowing individual transmitters to be deactivated. Not a bad score at all as if you round it off, it’s actually a perfect five already. A 120R terminator resistor is included with the board.
