DS1101 Programmable 3.5-channel
RS232 Controller

The DS1101 is a compact Tibbo BASIC/C-programmable controller with Ethernet and optional Wi-Fi* connectivity. The DS1101 targets serial-over-IP and serial control applications.

The DS1101 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 DS1101 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 DS1101. Alternatively, the DS1101 itself can be powered through the pin 9. The device can also be powered via its power jack or the available power-over-Ethernet module*.

In addition, the DS1101 can be equipped with a 96x32 monochrome OLED display.

There are eight LEDs on the device's front: green and red main status LEDs, yellow Ethernet link LED, and five blue LEDs, which can be used for Wi-Fi signal strength indication and other purposes. A buzzer is provided as well.

Each DS1101 is supplied with the DIN rail and wall mounting plates.

The DS1101 comes preloaded with a fully functional serial-over-IP (SoI) application that turns the DS1101 into a powerful serial over IP (SoI) device, a.k.a. the device server.

* Wi-Fi and power-over-Ethernet options are mutually exclusive.
