DS1206 as a 3.5-channel
RS232 Serial Device Server

The DS1206 is a compact Tibbo BASIC/Tibbo C-programmable RS232 controller with Ethernet connectivity.

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.

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

As a device server, the DS1206 is compatible with Tibbo Device Server Toolkit (TDST) for Windows. TDST includes the Virtual Serial Port Driver (VSPD), which enables you to use all serial channels of the DS1206 as remote COM ports of your PC. The Linux version of the VSPD is available as well.

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.
