RJ50 Serial (Enhanced UART)
The USB Centric I/O Board provides one full RS-232 serial port (Enhanced UART) through an RJ50 connector. The port has a shunt to select between +12V (default), +5V, or normal RI functionality. Maximum power capability is 1A from this port. The power output from this port is protected by a self-healing fuse.
