Each port includes RTS and CTS handshaking lines, as well as clockcontrol lines TXCLK and RXCLK for bit oriented synchronous protocols. Asynchronous portspeeds are generally 1200 to 115.2kbps, and other speeds dependent on bit orientedprotocols. When the RS-232 bit ports are configured for bit oriented protocol, the input andoutput bits are manually controlled by software. Bit protocols supported are per factory order.RJ45 PIN # Signal Type Signal NameJ7A-1 I/O Power GNDJ7A-2 I/O Power GNDJ7A-3 RS-422 TX+J7A-4 RS-422 RX+J7A-5 RS-422 RX-J7A-6 RS-422 TX-J7A-7 I/O Power +24Vdc OUT (Note 1)J7A-8 I/O Power +24Vdc OUT (Note 1) |
