2HARDWARE INTERFACES
2.1 Connectors
On the label on top of the device you can see an overview about all HW-Interfaces of
the 100BASE-T1 MediaConverter_BCM.
2.1.1 Black MQS Connector
The pinning of the ECU connectors is listed on the label on top of the device as well.
(See Figure 2—1).
The Connector color is black.
The power supply for the device is supplied by pin 1 (12 Volt) and pin 10 (Ground)
Warning: If you apply a voltage higher than 18 Volt, the device will be damaged!

2.2 Other Interfaces
2.2.1 DIP-Switches
The 100BASE-T1 MediaConverter_BCM has two DIP-Switches for configuration (see
Chapter 3).
2.2.2 Status LEDs
The 100BASE-T1MediaConverter_BCM 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 BR 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_BCM should always be set to FullOut. HalfOut
was a former configuration for EMC optimization but it will cause an instable link.

4100BASE-T1 FILTER
There are different BroadR-Reach Filter in different Hardware versions of the 100BASE-
T1 MediaConverter_BCM:
The following BR-Filter is used in the Hardware version 3.0:
In Version 3.0 the Würth CMC 510010003 is used for L32.
In Version 3.0a the TDK CMC ACT45L - 2 01 - 2P is used for L32.
Figure 4—1: BR-Filter for HW v3.0 and v3.0a
The following BR-Filter is used in the Hardware version 2.0:
Figure 4—2: BR-Filter for HW v2.0
All Filter versions are compatible, and it will be possible to set up a stable link. It is
recommended to use the latest filter version.
