When to use the RS485 carrier detect signal?
RS485 pinout Carrier Detect (CD) this control signal is used when a modem informs a computer that it has detected a carrier that the computer can use for data transmission. Receive Data (RXD) this line is used for data transmission between two sources. An example is data received from a modem transferred to a computer.
Which is better the RS232 or The RS485 interface?
The RS485 interface achieves superior transmission over greater distances and better data rate performance than the RS232 protocol. Transmission speeds of 30-35 Mbps are supported for distances of up to 10 meters. Data rates of 100Kbps can be achieved over distances of up to 1200 meters.
