 The CSAFE protocol is licensed on a royalty free basis to any company, person, or organization wishing to use it.Most of the pins from the RJ-45 plug should be connected to a normal RS-232 interface configured for an asynchronous communication mode of 9600 baud with 8 data bits, 1 stop bits and no parity.Hardware handshaking for flow control (CTS as an input to Slave) is not required to support this protocol but is recommended.
