The DS1202 is a miniature BASIC-programmable controller designed primarily for serial-over-IP and serial control applications. It comes preloaded with a fully functional serial-over-IP application.
The unique feature of the DS1202 is its multi-channel serial port. The device has a single DB9M connector and is priced as a single-port device, yet packs four independent serial channels. Have no use for those DSR and DTR lines? Turn them into RX and TX of an additional serial channel. Don't want CTS and RTS either? That's one more channel! In total, there are 15 different configurations to choose from.
