Figure 4: Using the RAD-Galaxy as a Media Converter.
The RAD-Galaxy allows a PC to interact with up to 12 Automotive
Ethernet nodes. Each node can send to the PC, and vice-versa, simultaneously.
Mixed Topology Operation
If the RAD-Galaxy is in active tap configuration, it is possible to connect a node to only one of
the two connections of any of its six pairs. With only one device in the pair, the node will only
be able to send and receive to and from the PC, effectively operating in media converter mode.
This allows you to “mix and match” how you use the 6 pairs in the device: for example, you can
use 5 pairs as active taps, and attach an addition device to the 6th pair by itself for use as a
media converter. This is depicted in Figure 5, which is just a slight variation on Figure 3.
Any combination of 6 active taps and 6 media converter connections is possible in this manner.
If you want to use the RAD-Galaxy as a media converter for more than 6 devices you must set
it into media converter mode as described earlier, which precludes using it as an active tap at
the same time.
