The TE1021 is a point-to-point conversion tool from 100/1000Base-T1 Car Ethernet to 100/1000Base-TX regular Ethernet. We provide a companion cable with D-SUB9 Car Ethernet connector and RJ-45 crystal header connector to facilitate the connection between ECU and PC with Car Ethernet interface.

The TE1021 can be selected in Master or Slave mode with the push of a button, and the Ethernet data will be converted losslessly between Car Ethernet and 100/1000Base-TX Ethernet communication. Data transmission is full duplex in both directions. Mode configuration can be done simply by completing the DIP switches.

The TE1021 will be the ideal low-cost converter tool between 100/1000Base-T1 Automotive Ethernet and PC systems.
Suitable for R&D personnel, ECU production lines, test engineers, after-sales engineers, etc.
