DS1101 Programmable 3.5-channel
RS232 Controller
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 that pin. 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.
The DS1101 comes preloaded with a full-featured serial-over-IP (SoI) application that turns the DS1101 into a powerful serial over IP (SoI) device (a.k.a. "device server"). A versatile Modbus Gateway application is also available.
Here is How You Can Use the DS1101
As a Serial-over-IP (SoI) Device
Serial-over-IP conversion is a large part of what we do, and there is an entire section of our website dedicated to serial converters (a.k.a. "serial device servers"). We offer an open-source serial-over-IP (SoI) app that turns the DS1101 into a full-featured RS232-to-IP converter.
As a Modbus
Gateway
Modbus is everywhere — it is virtually synonymous with industrial control! Our open-source Modbus gateway app allows you to seamlessly interconnect Modbus TCP, Modbus ASCII, and Modbus RTU masters and slaves.
Build Your Own
IoT Solution
The DS1101 is programmable in Tibbo BASIC and Tibbo C. Develop your very own IoT solution from scratch or take inspiration from our open-source applications and code samples published in the Code and Apps section.
