Tap Options - Enable Switch Mode
This is present only when the parameter above is set to
Tap
. It is reserved for future
functionality and currently does not affect the operation of the device. (Note specifically that
this does not cause the RAD-Galaxy to behave as an Ethernet switch.)
OP (BR) ETH1 - OP (BR) ETH12
Each of these entries contains the same parameters and controls the corresponding
100BASE-T1 channel on the RAD-Galaxy (Figure 68).

Enabled
Placing a checkmark in this box enables the channel, while clearing the checkmark disables it.
When disabled, the
Link Mode
parameter is disabled (grayed out).
Link Mode
Provides control over link negotiation for the channel. Automotive Ethernet requires each link
to have one device configured as master and the other as slave: the PHY of the master device
generates a shared clock signal for the channel, and the slave device’s PHY synchronizes to it.
By default, the RAD-Galaxy will automatically adjust to complement the other devices
connected to its channels. However, if necessary, you can use these settings to manually
override this behavior:
•
Auto:
The RAD-Galaxy will automatically configure itself as master or slave as required
to establish a link to the other device on this channel.
•
Master:
This channel will always act as a master device.
•
Slave:
This channel will always act as a slave device.
Note that the designation of a device as master or slave only matters for low-level clock
synchronization as described above. Aside from this, the devices are peers on the network; the
master does not control operation of the slave.
