1GENERAL INFORMATION
1.1 Functionality and Features of the 100BASE-T1
MediaConverter_EMC
The Technica Engineering 100BASE-T1 MediaConverter_EMC is always in a set of
two devices. One Device transmits data frames directly from the physical layer
100BASE-T1 to a proprietor optical Ethernet SFP-module port. The Delay time is
constant 2.0µs. The standard operational area is getting a connection to a device
under test in a shielded EMC Chamber. The recommended application can be seen in
the following picture:

2.1.2 SFP-Interface
There is one SFP cage for a MiniGBIC module.
It is not possible to use standard SFP-modules in this SFP-cage. In the parts list of the
100BASE-T1-MediaConverter_EMC_Set there are special reworked optical SFP-
modules, which are matching to the 100BASE-T1 MediaConverter EMC. It is
recommended to use these modules.
2.2 Other interfaces
2.2.1 DIP-Switches
The 100BASE-T1 MediaConverter_EMC has two DIP-Switches for configuration (see
Chapter 3).
2.2.2 Status LEDs
The 100BASE-T1 MediaConverter_EMC_Set 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 EMC 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 must be set to Master, the other must be set
to Slave Mode.
Note: The MediaConverter should always be set to FullOut. HalfOut was a former
configuration for EMC optimization but will cause an instable link.

4EMC Measurement Setup
The following diagram shows a typical EMC measurement setup.
The device under test is placed in a shielded EMC chamber together with one optical
MediaConverter. All devices inside the chamber are supplied by a 12 V car battery.
The only connection to the outside is a fiber Ethernet connection so no guided
radiation can occur.
The optical MediaConverter has been built to be EMC clean. So the source of all
radiation measured in the chamber will be the DUT.

5100BASE-T1 FILTER
The following 100BASE-T1 Filter is used in the 100BASE-T1 MediaConverter_EMC:
In Version 3.0 the TDK CMC ACT45L-201-2P is used for L32.
All Filter Versions are compatible and it will be possible to set up a stable link.
However, it is recommended to use the latest filter version.

6GENERAL EMC TEST INFORMATION
Testcases:
We test our EMC products with 350 V/m in a Stripline setup from 1 MHz to 1 GHz. The
devices are not damaged in this setup.
There will be no Link Drop on 100BASE-T1 or 1000BaseT1.
Warning: At frequencies below 1 MHz immunity must be tested at a maximum of
100V/m. Otherwise the devices will be permanently damaged!
We test our EMC products with 200 mA in a BCI substitution setup from 1 MHz to 1
GHz. The devices are not damaged in this setup.
There will be no Link Drop on 100BASE-T1 or 1000BaseT1.
Warning: BCI closed loop method is not allowed for 100BASE-T1 or 1000BaseT1
products. This test would permanently damage any device (independent of the vendor
of device) if your generator is strong enough.
Warning: At frequencies below 1 MHz the immunity must be tested at a maximum of
40 mA. Otherwise the devices will be permanently damaged!
Emission:
We test our EMC devices according to automotive emission standards. Because
standards and expectations vary, we grant a 4 week return period. You can test our
device according to your needs in your chamber. If you are not satisfied with the result
you can return the devices and get refunded.

7ADDITIONAL INFORMATION
•The delay time is constant 2.0µs. The delay is independent of the Ethernet packet
frame size.
•The 100BASE-T1 MediaConverter_EMC is optimized for automotive use. The
maximum line length for each BroadR-Reach segment is limited to 15 meters.
•For best EMC performance only linear power regulators have been used in the EMC
version of the MediaConverter. The case has been designed to act as a heat sink.
•At 12 Volt VBAT the loss is very big. If you have the chance to use 10 Volt VBAT
this would prevent the device getting hot.
