Figure 5: RAD-Star Conventional Ethernet Side.
The standard Ethernet RJ-45 jacks on this side of the RAD-Star
correspond to their equivalently-named jacks on the Automotive Ethernet side. Each has a link LED (above and left of the
port) and activity LED (above right). The
CAN+PWR
port provides power to the device using an industry-standard DB-9 CAN
connector.
There is no need to configure standard Ethernet ports as master or slave. The labels on the
jacks here are instead used to match up the conventional Ethernet ports with their Automotive
Ethernet equivalents, as follows:
•
SLAVE:
Carries copies of messages transmitted by the AE device connected to the
RAD-Star’s
BR SLAVE
port, as well as messages from an attached PC intended for that
device.
•
MASTER:
Carries messages coming from the device on the
BR MSTR
port, or going to
that device.
Each RJ-45 has a pair of integrated LEDs that provide information about it:
•
Link LED (Above Left):
Indicates that a valid link has been established between the
RAD-Star and the conventional Ethernet network.
•
Activity LED (Above Right):
Flashes when traffic passes in either direction over the
attached Ethernet cable.
When the RAD-Star is used as an active tap, both ports will have their link LEDs on, and their
activity LEDs will flash at a rate proportional to the amount of data being transferred. Using the
RAD-Star as a media converter will result in the LEDs being lit on the port with the attached
cable, while those on the other port will remain dark.

Hardware and Software Requirements
You will need a small amount of support hardware to effectively use the RAD-Star, with the
exact equipment requirements depending on the intended application. Note that cabling
requirements are described in more detail in the section following this one.
