The reason of that my datalogger is too far away from my converters, i want to use RF modems to establish communication between the datalogger and the converters.
The RF modem i have supports RS232 and RS485 at the moment and the baud rate od the modem is optional within standart range like(57600,19200,9600,2400 etc.).
I want to ask that what is the standart of communication between the data logger and the converters. And what is the speed?
Have a nice work,
