10BASE-T1S Media Gateway

The 10BASE-T1S Media Gateway is a flexible 10BASE-T1S switch with CAN(/FD) gateway and user programming features. The device offers one 10BASE-T1S port, one Fast Ethernet port, a CAN channel with CAN FD support, and a USB 2.0 port.

10BASE-T1S Media Gateway Data Sheet

The media gateway can be used as a 10BASE-T1S – Ethernet switch (media converter) enabling a bi-directional communication between the 10BASE-T1S port, the standard Ethernet port, and the MCU, or as an Ethernet-CAN(/FD) gateway providing a data bridge between the Ethernet ports (10BASE-T1S and 100BASE-TX) and the CAN(/FD) channel. Gateway function for bridging a 10BASE-T1S network and a CAN/CAN FD bus can be configured over the embedded web server. The device can also be used as a USB to CAN(/FD) and an Ethernet – CAN(/FD) interface.

The Single-Pair Ethernet 10BASE-T1S port supports both CSMA/CD and PLCA modes, and allows for point-to-point and multi-drop network topologies. The port configuration, such as mode, BEACON transmission (PLCA coordinator), Node ID / Node count, and bus termination, can be easily set by on-board DIP switches.

C language SDK

The user can use the free-of-charge C language SDK to develop a custom device firmware. This provides the user a full control over the MCU and its peripherals, and extends the use-case scenarios. The SDK allows to use the on-board Ethernet switch and the ETH ports (MCU, 10BASE-T1S, 100BASE-TX), CAN(/FD) channel, LEDs, and DIP switches.
