The DS1000, DS1002, and DS1003 are 4-port BASIC-programmable industrial controllers designed primarily for serial-over-IP and serial control projects. All three devices come preloaded with a fully functional serial-over-IP application (open-source).
These devices differ in the type of serial ports they offer:
With its four conventional RS232 ports, the DS1000 is ideal for relatively low-cost projects.
For applications requiring a mix of port types, there is the DS1002, which sports universal RS232/422/485 ports with programmable selection of each port's mode.
Finally, especially demanding industrial installations can rely on the DS1003, which adds galvanic isolation on top of the universal ports.
