The Axiomatic High Speed Automotive Ethernet to Ethernet Converter provides a purely physical, bi-directional conversion between Automotive Ethernet (1000BASE-T1), and Ethernet (1000BASE-TX) via PHY transceivers. No packets are stored or modified in this device. The converter supports a baud rate of 10, 100, and 1,000 Mbit/s. Status LEDs provide information on connection link, and communication. The converter is designed for the harsh environments of off-highway or industrial equipment. Automotive Ethernet networks use a 2 wire, unshielded, twisted pair (UTP) cable. Using Automotive Ethernet saves cabling costs for the machine builder.

The unit will be configured via the CAN (SAE J1939) port to act as a Master or Slave for Automotive Ethernet. The Master mode works if the connected device has its transceiver set to slave mode. The Slave mode works when the connected device has its transceiver set to master mode. Hard setting the master/slave relationship saves on setup-time costs and ensures that the Automotive Ethernet link is established quickly. As a comparison, regular Ethernet converters rely on auto-negotiation to determine master and slave.
