The DS1206 features a multi-channel RS232 port. The device has a single DB9M connector and is priced as a single-port product, yet packs 3.5 independent serial channels.

Another feature of the DS1206 is its software-controlled power output on pin 9 of the DB9 (serial port) connector — you can power an attached serial device directly through the DS1206. Alternatively, the DS1206 itself can be powered through the pin 9.
