With an integrated CANbus connector, the UNO-1251G is especially suitable for networking intelligent I/O devices such as sensors and actuators. Originally designed by Bosch, CANbus is characterized by its multi-master protocol, real-time capability, error correction, high noise immunity, and the existence of many different silicon components.

To aid development of CANbus applications the UNO-1251G includes the Advantech CANopen Protocol Library, which provides a C application programming interface (API) with which to use, configure, start and monitor CANopen devices.

To aid internet connection in areas where using wires is impractical, the UNO-1251G includes an easily accessible side mounted expansion slot which can be used for installing an optional wireless card without having to open up the entire unit.

The UNO-1251G has been designed to be operated remotely from any computer or tablet with a VNC (Virtual Network Computer) client installed and engineers can remotely access the UNO-1251G for diagnosis & control from wherever they are. Through WebAccess it helps move from proprietary systems to an open architecture and ease the integration of different devices.

The programmable OLED display provides operators with intuitive system status messages. It comes with a range of default messages, but is also able to be programmed, using the OLED Display API, by site engineers so specific messages can be shown.

As well as the RISC 32 bit ARM Cortex-A8 processor, the UNO-1251G also includes externally accessible micro SIM for 3G access and a micro SD card slot for additional storage, USB port, two 10/100 LAN ports, LED indicators, integrated 1G micro SD Card with OS installed and three COM Ports.
