Multi-channel RS232 Port
The DS1206 features a multi-channel RS232 port. Internally, the DS1206 has four
independent serial ports, and each of those ports can potentially have its own RX,
TX, CTS, RTS, DSR, and DTR lines. Physically, the RS232 port of the DS1206 has
three output lines and four input lines. Flexible mapping allows you to choose how
these inputs and outputs will be used.
The serial-over-IP application supplied with the DS1206 defines 15 mapping options.
