Tibbo Programmable Device Serial Controllers Comparison table
Tibbo serial controllers are device servers with a twist: While excelling at their primary use as serial-over-IP (SoI) converters, they can be used as programmable Internet of Things (IoT) nodes and adapted to perform a myriad of customized jobs.

Compact and versatile, these devices are perfect for network-enabling legacy serial systems, remotely controlling serial devices, as well as collecting and sending serial data to the cloud.

Feature-rich and easy-to-learn, the Tibbo BASIC and Tibbo C programming languages open up a world of application possibilities. Control serial devices and machinery. Collect, store, and manipulate data. Communicate with cloud services and more.

Ready to go

Coding not your thing? Use the preloaded Serial-over-IP (SoI) application or download one of our free, ready-to-use apps, like the Modbus Gateway. Our team of experts can also design an application for you. You spec it — we do the rest.

Choice of serial ports

  • WS1102 – RS232/422/485 port
  • DS1100 – simple RS232 port with power input
  • DS1101 – 3.5-channel RS232 port with power input/output
  • DS1102 – 3-channel RS232/422/485 port

Wireless Connectivity

Looking to improve your system's reliability by providing an additional communication path in case the Ethernet link goes down? Order the DS1101 or DS1102 controller with the Wi-Fi option.

Planning to go all-wireless? The WS1102 controller with Wi-Fi and BLE interfaces is your answer!

Optional power-over-Ethernet (PoE)

Cut the power cord and power your DS1100, DS1101, or DS1102 controller directly through the Ethernet cable!

The available PoE add-on is a true 802.3af device. It is compatible with a wide range of PoE-enabled switches and "power inserters."

Optional OLED display

The 96x32 OLED display available on the DS1101 and DS1102 devices is perfect for simple text and graphics.

Show messages, icons, status info, and prompts. To get inspired, see how we use the display in our Serial-over-IP (SoI) application.

Mounting not Optional

A DIN rail mounting plate is included with each serial controller. Not just a slap-on afterthought, our DIN rail plate is artfully fused into the product's body and accentuates its appearance.

Mounting your controller on a wall? One wall mounting plate also comes with each device.
