Data Sent By The Automotive Ethernet Device Is Not Received; Data Sent By The Conventional Ethernet Device Is Not Received - Keysight APM0100E User Manual

Data Sent by the Automotive Ethernet Device is Not Received

Check the Rx LED on the 100BASE-T1/Ethernet Media Converter. If it is not
flickering, then data is not received by the 100BASE-T1/Ethernet Media
Converter. Double-check the attached device to ensure that it is transmitting, and
the BroadR-Reach (100BASE-T1) cable is functional.
If the Rx LED is lighting up, check the link to the conventional Ethernet device,
and try a different cable if possible.
If both attached devices and cables seem to be correct, the issue may be with the
100BASE-T1/Ethernet Media Converter; then, contact Keysight
Support"

Data Sent by the Conventional Ethernet Device is Not Received

The conventional Ethernet side has combined transmit and receive LEDs, so first
disconnect the BroadR-Reach (100BASE-T1) cable from the 100BASE-T1/
Ethernet Media Converter. This action will ensure that any flickering of the Activity
LED indicates data received by the 100BASE-T1/Ethernet Media Converter from
the conventional Ethernet device (rather than data the 100BASE-T1/Ethernet
Media Converter is transmitting). By performing this action, if you do not see this
LED lighting up, the device may not be transmitting, or there may be a problem
with the regular Ethernet cable.
If the Activity LED is lighting up, reattach the BroadR-Reach (100BASE-T1) cable
to the 100BASE-T1/Ethernet Media Converter, and check the connection to the
Automotive Ethernet device. Try with a new cable if possible.
