Converter acts as an Ethernet network interface card when plugged into an USB port.
The 100BASE-T1 USB Interface (Media Converter) connects a 100BASE-T1 network to any computer with an USB port. The interface easily connects Automotive Ethernet devices with OPEN Alliance BroadR-Reach (OABR) port, such as cameras or ECUs, directly to any PC without a need of an on-board network card.
The interface establishes a point-to-point link between an unshielded twisted-pair IEEE 100BASE-T1 (IEEE 802.3bw) port and USB-LAN port and works as a Network Interface Card allowing the user to configure the network adapter’s parameters, such as IP address and mask. The converter features a DSUB9 (BroadR-Reach, CAN bus) and Micro-USB connector. The OABR channel’s Master/Slave configuration is selected by a switch button or programmatically.
100BASE-T1 USB Interface offers a possibility to access SMI registers of the 100BASE-T1 transceiver (PHY) via a CAN bus or a USB’s virtual serial port. This enables the user to evaluate signal strength, detect polarity of the T1 port, carry out a BroadR-Reach media test to diagnose cable errors, fine-tune the PHYs parameters, and generally to read and write the registers.
