Pinouts
OmniSwitch 6900 RS-232 console ports use either an RJ-45 connector or a USB connector. (Refer to
diagrams below.) Three signals are used: Transmit Data (TXD), Receive Data (RXD) and Signal
Ground (GND).
Note. No hardware handshaking (RTS, CTS) is used. Instead, software flow control (XON, XOFF) is
required, where XON is equal to ready and XOFF is equal to not ready.
