Hi
i have an electronics meter of iskra company model MT860s. But i dont know that have to test its rs485 port communication bcoz i turned it on but this give no data on rs485 port. Is there need any configuration pls illustrate it is urgent .
after check your meter specs your meter support RS232,IR and RS485 , and if you prepare the setup the meter will not send data without you send the Reading command, and you should have IEC 62056-21 software to communicate with meter
