E2CAN MKII Gateway

Your choice for easy link of I/O to Ethernet, USB or CAN Interface.



The BRUNNER Ethernet-to-CAN (E2CAN) Gateway MKII is a powerful high-speed Ethernet to CANopen gateway that provides easy and flexible access to CAN networks via PC.
The two high-speed CAN connectors allow daisy chaining of the device in your CANopen network. The application on the host communicates over a standard TCP/IP socket with an ASCII protocol.

Further, our E2CAN Gateway provides a USB to CANopen gateway functionality whereas the device shows up as a USB HID game controller, so no driver installation is necessary. The gateway can handle up to 100% CAN-bus load via Ethernet, and is therefore particularly suitable for data-intensive applications.

The E2CAN Gateway offers comprehensive filter and analysis functions for CANopen through integrated dual TCP/IP socket server that allows the connection of up to 2 Client Sockets to the same CAN Network. This unique feature enables the use of the MK II Gateway as a CAN sniffer for various failure and performance analysis. CAN sniffer functionality is provided as well over the integrated USB HID port.

The E2CAN Gateway is powered over USB or external Power Supply. The easy configuration utilizes the web interface or our CANopen Commander Software. The E2CAN Gateway MK II has a robust industrial design and snap-on mounting possibility on various top hat DIN rails, which allows fast mounting and connection.
