DS1206 Programmable 3.5-channel
RS232 Controller

The DS1206 is a compact Tibbo BASIC/C-programmable controller with Ethernet connectivity. The DS1206 targets serial-over-IP and serial control applications.

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.

The DS1206 comes preloaded with a fully functional serial-over-IP (SoI) application that turns the DS1206 into a powerful serial over IP (SoI) device, a.k.a. the device server.
