The X7R from Waysion Technology (China) is a 7-inch tablet PC designed to operate within truck in-cab and other applications within harsh environments.

CAN Bus interface maintains data communications via an extension cable, and it supports the 29-bit CAN-identifier. If required, the SAE J1939 higher-layer protocol can be implemented using an additional converter. The device receives data from CAN Bus based in-vehicle networks, process it internally, display the data, and direct the data to the tablet’s interfaces. Bit-rates from 50 kbit/s to 1 Mbit/s are possible with 250 kbit/s and 500 kbit/s used per default. The physical CAN Bus port comes with a 9-pin male D-Sub connector. 

The range of interfaces includes EIA-232, EIA-422, Gigabit Ethernet (RJ45), USB host (type A), and GPIOs (general purpose IOs). For wireless communication, modules such as Wifi, Bluetooth, 4G cellular, NFC, and GPS are available. Furthermore, Waysion offers the CANMonitor test and integration software used for the debugging and development of customized applications. 

According to the manufacturer, the device has been widely deployed by clients working on in-vehicle systems such as fleet management, mining proximity detection, precision farming, and other general applications for industrial or IoT (Internet of Things) use.
