counter, multiplies its value by 3, stores the result in a 16-bit data field and transmits the
product back to the client.
To actively tap this communication, we disconnect the client and server nodes from each
other, and then attach the client node to BroadR-Reach channel 1 of the RAD-Galaxy and the
server node to BroadR-Reach channel 2. We could of course do this the opposite way (client
to channel 2 and server to channel 1) and it would work the same. We could also have used a
different pair of channels (such as 3 and 4) but not channels from different pairs (such as 2 and
3).
If you want to duplicate this exercise, then set up any sort of client/server exchange using two
Automotive Ethernet nodes, and then connect them to the RAD-Galaxy in the same way we
have. After correctly tapping the link using channels 1 and 2, you should see the green activity
LEDs below the numbers 1 and 2 on the left side the device flashing. You can now go online to
monitor the traffic exchange using the RAD-Galaxy and Vehicle Spy.

(BR) ETH02, which are the messages our nodes are sending. There may be other traffic that
