5.3 Using the RAD-Galaxy as an Ethernet Media Converter
When set to media converter mode, the RAD-Galaxy treats each connected device
independently, rather than as tapped pairs. To see how this works, we’ll demonstrate the
difference in behavior when this mode is activated, using the same setup we created in
Section 5.2.
Upon completing the previous section, you will have both an Ethernet client node and Vehicle
Spy sending requests to a server node, which replies with a response to each request. Let’s
see what happens if we switch the RAD-Galaxy from tap to media converter operation.
1. Start neoVI Explorer:
Click the button located in the main Vehicle Spy toolbar just
under its menu; the neoVI Explorer window appears. (If you require assistance with
using neoVI Explorer, please refer back to Chapter 4).
2. Connect to the RAD-Galaxy:
Click the RAD-Galaxy in the hardware list and then press
the
Connect
button.
3. Change to Media Converter Mode:
Select
One Pair Ethernet (BroadR)
in the
parameter group tree, then click the drop-down box on the right and change its selection
from “Tap” to “Media Converter”.
4. Save Changes:
Press the
Write Settings
button to update the RAD-Galaxy.
5. Exit neoVI Explorer.
6. Switch to Messages View.
7. Go Online.
8.
Go Offline.
Notice the differences now when you examine
Messages View
. You will still see
Client Request
messages from the Ethernet client device attached to RAD-Galaxy channel 1, and
VSpy
Client Request
messages coming from Vehicle Spy on the PC. Each
VSpy Client Request
will
have a
VSpy Server Response
message right after it as before. However, the
Client Request
messages will not have prompted the sending of
Node Server Response
messages by the
server device on channel 2. Since the RAD-Galaxy is in media converter mode, traffic from
channel 1 is not forwarded to channel 2 (and vice versa) so the Ethernet device acting as a
server does not see the
Client Request
messages sent by the Ethernet device acting as a
client. It only sees the
VSpy Client Request
messages from the PC.
5.4
Monitoring Conventional Vehicle Network Traffic
The RAD-Galaxy can be easily used to view all of the messages on your conventional CAN
networks, and support for LIN will be forthcoming in a future firmware update. If you’ve used
Intrepid vehicle network tools before, the process will be very familiar, and requires very little
setup.
