As soon as you connect the DB-25 or OBD-II connector, the RAD-Galaxy should power up.
You will recognize this by seeing LEDs light up on the left side of the device (again, see

3.5 100BASE-T1 (BroadR-Reach) Network Connections
Now we will make the 100BASE-T1 (BroadR-Reach) connections between the RAD-Galaxy
and our Automotive Ethernet network. Assuming that the correct cable assemblies have been

of the cable assemblies you created into the matching sockets on the RAD-Galaxy
(Figure 51). The connectors are keyed, and you should hear a slight click when the plug
is correctly seated. Notice the release tab, which you will use if you want to remove the
connector later on.

If you are planning to use the RAD-Galaxy as an active tap, remember to interpose the RAD-

1+2, 3+4, 5+8, 7+6, 9+10 or 11+12. For example, if a node is connected to a switch port, then
