NettetRS485 Standard. The RS485 Standard is similar to the RS422 standard upon which it is based. The main difference is that up to 32 transmitter receiver pairs may be present on the line at one time. A 120 Ohm resistor should be used to terminate either end of the main line. If more than one device may transmit data, the RTS line is used as a ...

Nettet6. mai 2024 · The output is in RS232 level, i.e. it contains negative voltages and goes up to 12V (the power supply level). I've used a voltage divider and a schottky diode so that I only get positive voltages up to about 3V. I don't know if this is relevant. I should get 16 bytes from each card, and I do.
