Automotive Ethernet Link LED is not Illuminated
The RAD-Moon is not linked correctly to the BroadR-Reach device. Since BroadR-Reach
devices and cables may vary, this issue may be application-dependent. However, please try
the following:
• Double-check the connections at both ends of the cable.
• Remove the cable from the RAD-Moon and reconnect it.
• Check for a loose connection at the Automotive Ethernet device.
• Try a different cable, if possible.
Err LED Lights Up
Errors can occur occasionally on correctly-functioning Ethernet networks, so it is not a
problem to occasionally see the Err LED flicker. However, if you see this often, or the LED is lit
continuously, this typically indicates a problem that must be resolved.
Here are some suggestions:
• Fully check the setup of the device to ensure all cables are connected correctly.
• Try connecting the RAD-Moon to a different BroadR-Reach device. If this solves the
problem, the issue is likely related to that particular device.
• Connect the RAD-Moon to a different Ethernet port, device or network. Again here,
resolution of the issue in this way indicates a problem with the attached Ethernet unit.
• Unplug the USB connection from the RAD-Moon and then reconnect it. If this fixes the
problem but it occurs again shortly thereafter, please contact Intrepid for assistance.
Note that if you are connecting the RAD-Moon to a shared Ethernet network—one that uses
hubs rather than switches—you may see more errors than usual. Very few modern networks
are set up in this manner, however.
Data Sent by the Automotive Ethernet Device is Not Received
Check the Rx LED on the RAD-Moon. If it is not flickering, then data is not actually being
received by the RAD-Moon. Double-check the attached device to ensure that it is transmitting
and the BroadR-Reach 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 RAD-Moon
itself; please contact Intrepid.
