2.2 Other Interfaces
2.2.1 DIP switches
The 100BASE-T1 MediaConverter_NXP has two DIP switches for configuration (see
CHAPTER 3).
2.2.2 Status LEDs
The 100BASE-T1 MediaConverter_NXP has two status LEDs at the frontside of the
case for the 100BASE-T1 Port.
Upper LED:
Green Color. It is lit when there is a linkup on the 100BASE-T1 port.
Lower LED:
Yellow Color. It is toggling in alternation with the green LED when there is
communication.
Note: There is a bug in the used BroadR-Reach PHY. When the 100BASE-T1 Plus and
Minus lines are swapped, and the 100BASE-T1 port is set to Slave then the Link LED is
lit, but there is no data transmission possible. So please connect the 100BASE-T1 lines
correctly.

3CONFIGURATION OF THE DEVICE
The 100BASE-T1 MediaConverter is configured by two DIP switches on the front of the
device.
DIP-Switch
Status
Description
1
ON (up)
OFF (down)
100BASE-T1 Port is set to Master
100BASE-T1 Port is set to Slave
2
ON (up)
OFF (down)
100BASE-T1 Port is set to FullOut
100BASE-T1 Port is set to HalfOut
Table 3—1: Configuration of DIP-Switches
Note: In a 100BASE-T1 Link one device has to be set as Master, the other has to be set
as Slave.
Note: The 100BASE-T1 MediaConverter_NXP should always be set to FullOut. HalfOut
was a former configuration for EMC optimization but it will cause an instable link.

4STANDARD USE CASE
Here you can see a standard use case of the 100BASE-T1 MediaConverter_BCM:
Figure 4-1: Example for use case
MC: MediaConverter
DUT: Device under Test.
DIP-Switch 2 should be always ON, DIP-Switch 1 is dependent of the DUT. If DUT is
Master, MC must be configured as Slave (DIP-switch 1: OFF) and vice versa.

6ADDITIONAL INFORMATION
The 100BASE-T1 MediaConverter_NXP is optimized for automotive use. The
maximum cable length for 100BASE-T1 segments is limited to 15 meters
The difference between the 100BASE-T1 MediaConverter_BCM and 100BASE-
T1 MediaConverter_NXP is the used transceiver for the 100BASE-T1 PHY. In the
beginning of development there were problems with the interoperability of
different PHY manufacturers. Now the interoperability is given, and the
functionality is independent from the PHY manufacturer.
