MACH-ETH

SKU #: MA-MACH-ETH
New

The MACH-ETH is an automotive network interface that features one Ethernet port, two CAN FD channels, a LIN channel, a USB and RS-232 port, and multiple I/Os. The device can act as a Ethernet-CAN(/FD) or Ethernet-LIN interface as well as CAN(/FD)-LIN gateway, and a user-scripting feature allows to run user applications directly on the device. The open communication protocol enables access to interface’s channels over Ethernet or USB.

The communication protocol over Ethernet or USB enables access to CAN(/FD) and LIN bus channels over TCP/IP or virtual COM port respectively.

A user-scripting feature, which allows to run user applications directly on the MCU, can be used for HiL testing and rest-bus simulations. The device can act as an interface, a gateway, or bridge between all its channels.

An analogue input and a digital output enable the user to interact with external peripherals.

Integration

The open communication protocol (API) allows you to easily access CAN(/FD) and LIN channels over Ethernet TCP/IP or USB VCP. Over the protocol, the user can configure the CAN/CAN FD/LIN channels and transmit and receive frames.
