ZD-SafeLink ETH

Due to the point-to-point connection characteristics of Automotive Ethernet, integrating data acquisition devices into vehicles requires tedious wiring harness modifications. In addition, if the Ethernet connection becomes invalid due to the failure of the test equipment, it can directly affect the functionality of the entire vehicle. ZD's proprietary ZD-SafeLink ETH maintains the normal connection of the Automotive Ethernet through a passive reset design. When it is necessary to connect test equipment, any Ethernet port can be switched to the test equipment access side as needed. When used with the ZD Datalogger3 Series, the ZD-SafeLink ETH can actively reset the Automotive Ethernet connection to the original vehicle communication when the datalogger diagnoses a system error.

Application Scenario

When users need to connect the datalogger to test equipment, they can first reroute the datalogger's Ethernet interface port to the ECU Automotive Ports side of ZD-SafeLink ETH, then connect the test equipment's Ethernet port to the logger Automotive Ports side of ZD-SafeLink ETH. ZD-SafeLink ETH supports simultaneous connection of four channels of Automotive Ethernet. When the internal relay is in the connected state, the data logger maintains a normal connection to the ECU, and the Datalogger can act as a bypass device to receive the communication data from ECU.

To restore the original Automotive Ethernet connection, based on the working principle of ZD-SafeLink ETH, it can be divided into Passive Mode and Active Mode.

Passive mode: Users can perform the reset operation through the power supply (corresponding to the VBAT pins of the aviation connector), DIP switches, and program control.

Active Mode: Users can perform the reset operation by trigger (corresponding to the trigger pins of the aviation connector).
