WebDec 17, 2024 · These signals are the primary RS232 signals, but the protocol allows for secondary signals as well. They include secondary DTE, RTS, DCD, TxD, and RxD. The secondary signals are used to optionally connect DTE and DCE equipment. RS-232 cables Null modem connection Null modems enable serial communication between DTE and … WebDec 17, 2024 · The TxD+ and TxD- lines carry transmit data while the RxD+ and RxD- contain the receive data. The distances these signals are carried is greater due to differential signals. The RS485 interface achieves superior transmission over greater distances and better data rate performance than the RS232 protocol.
