Rs232 rts/cts
WebOriginal use of RS232. When we look at the connector pinout of the RS232 port, we see two pins which are certainly used for flow control. These two pins are RTS, request to send and CTS, clear to send. With DTE/DCE communication (i.e. a computer communicating with a modem device) RTS is an output on the DTE and input on the DCE. WebMany converters from RS-232 to RS-485 are "port-powered converters" in which the RS-485 power is derived from the RS-232 RTS line (or sometimes a combination of the RTS and CTS (DTR) lines). Because the power available from an RS-232 port is limited, the RS-485 launch voltages are not achieved when using a port-powered converter with, for ...
