DS1102 Programmable 3-channel
RS232/422/485 Controller

The DS1102 is a compact Tibbo BASIC/C-programmable industrial controller with Ethernet and optional Wi-Fi* connectivity. The DS1102 targets serial-over-IP and serial control applications as well as industrial automation solutions.

The DS1102 features a multi-channel RS232/422/485 port. The device has a single DB9M connector and is priced as a single-port product, yet provides 3 independent RS232 channels, 2 independent RS422 channels, or a single RS485 channel.

The device can be powered via its power jack or the available power-over-Ethernet module*.

In addition, the DS1102 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 DS1102 is supplied with the DIN rail and wall mounting plates.

The DS1102 comes preloaded with a fully functional serial-over-IP (SoI) application that turns the DS1102 into a powerful serial over IP (SoI) device, a.k.a. the device server.

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