Overview
The 100BASE-T1/Ethernet Media Converter is a powerful yet inexpensive tool that
effectively bridges the gap between Automotive Ethernet and conventional
Ethernet.
100BASE-T1/Ethernet Media Converter consists of the following:
– One BroadR-Reach (100BASE-T1) Automotive Ethernet port
– One standard, 4-wire 10/100 Mb/s Ethernet port
Data received on either port is copied to the other, allowing you to connect an
Automotive Ethernet ECU to a standard PC network interface card or Ethernet
switch. Powered by USB for convenience, the 100BASE-T1/Ethernet Media
Converter is packaged in a rugged, lightweight enclosure, making it easy to take
anywhere it's needed.
The 100BASE-T1/Ethernet Media Converter is ideal for monitoring, analysis,
diagnostics, and other applications in an Automotive Ethernet environment.

Introduction 2
Keysight APM0100E 100BASE-T1/Ethernet Media Converter User Guide 13
Operation and Features
Understanding 100BASE-T1/Ethernet Media Converter's design will help you get
the most out of its operation and features.
General Operation
The 100BASE-T1/Ethernet Media Converter contains two different Ethernet
physical layer implementations (PHYs) that are internally connected as follows:
– A BroadR-Reach (100BASE-T1) PHY
– A conventional 10/100 twisted-pair Ethernet PHY
You can connect an Automotive Ethernet ECU or device under test (DUT) to the
BroadR-Reach (100BASE-T1) PHY using the 100BASE-T1/Ethernet Media
Converter's Molex Mini50 connector, while a regular Ethernet device attaches
through the 100BASE-T1/Ethernet Media Converter's RJ-45 jack.
Data received over either connection is automatically sent out on the other,
creating a seamless link between the two attached devices. Full-duplex operation
is supported so that data can be sent in both directions simultaneously.
100BASE-T1/Ethernet Media Converter's standard mini-USB connector provides
power to the device. Several LEDs provide useful information about the status of
the converter.
A typical application of the 100BASE-T1/Ethernet Media Converter is to connect
an Automotive Ethernet ECU to the Ethernet jack on a laptop or desktop PC.
Ethernet frames from the ECU can then be monitored using Intrepid's Vehicle Spy
3 software. Messages can also be transmitted from Vehicle Spy 3 through the
100BASE-T1/Ethernet Media Converter to the ECU, allowing any Automotive
Ethernet device to be queried, tested, and managed.
Features
The following lists the features of the 100BASE-T1/Ethernet Media Converter:
– Powered by an industry-standard mini-USB connection
– Broadcom BCM89810 BroadR-Reach (100BASE-T1) PHY
– Automatic master/slave configuration for the attached Automotive Ethernet
device

2Introduction
14 Keysight APM0100E 100BASE-T1/Ethernet Media Converter User Guide
– Molex Mini50 for Automotive Ethernet connection
– Standard RJ-45 for 10/100 Ethernet connection with an automatic
configuration for 10 Mb/s or 100 Mb/s Ethernet networks
– Link and activity LEDs for both connections.
– Full-duplex support for simultaneous data transmission and reception across
both PHYs
– Rugged aluminum enclosure with rubber bumpers for durability
– Ethernet cable and USB cable included
Figure 2-1 shows the main functional elements of the 100BASE-T1/Ethernet
Media Converter. The two PHYs are connected directly to each other via the
standard Ethernet Media Independent Interface (MII).

Introduction 2
Keysight APM0100E 100BASE-T1/Ethernet Media Converter User Guide 15
Interfaces and Indicators
All of 100BASE-T1/Ethernet Media Converter's components are located on its two
sides, making the device easier to use in cramped quarters. The two sides are as
follows:
– Conventional Ethernet Side
– Automotive Ethernet Side
Conventional Ethernet Side
Figure 2-2 shows the side of the 100BASE-T1/Ethernet Media Converter that
attaches to a conventional Ethernet network. The two components are as follows:
–RJ-45 Port: An industry-standard conventional Ethernet jack with integrated
Link and Activity LEDs that provide information about the 100BASE-T1/
Ethernet Media Converter's conventional Ethernet connection:
–Link LED (Green): Indicates that there is a valid connection between the
100BASE-T1/Ethernet Media Converter and another 10/100 Ethernet
device.
–Activity LED (Orange): Flashes when traffic passes in either direction over
the attached Ethernet cable.
In normal operation, you should see the Link LED is always on, and the
Activity LED flashing at a variable rate, with faster flashing meaning a higher
data transfer rate.
–Mini-USB Port: A standard mini-USB port that provides power to the device.

2Introduction
16 Keysight APM0100E 100BASE-T1/Ethernet Media Converter User Guide
The 100BASE-T1/Ethernet Media Converter's standard 10/100 Ethernet
connection will automatically negotiate to match the speed of the Ethernet device
to which it is attached. In most cases, it will run at 100 Mb/s, though it will
support connection to a device that runs at 10 Mb/s. The 100BASE-T1/Ethernet
Media Converter can be forced to run at either 10 Mb/s or 100 Mb/s by forcing
the other device to the desired speed.
Automotive Ethernet Side
This side of the 100BASE-T1/Ethernet Media Converter contains just one
interface — a Molex Mini50 jack shown in Figure 2-3. While there is no
standardized Automotive Ethernet connector type, many BroadR-Reach
(100BASE-T1) devices, which include the Broadcom switches and other
Automotive Ethernet hardware, use the Molex Mini50. The BroadR-Reach
(100BASE-T1) connection automatically configures itself as master or slave as
needed.
Figure 2-3 100BASE-T1/Ethernet Media Converter Automotive Ethernet
Side
The four LEDs indicate the status of the 100BASE-T1/Ethernet Media Converter’s
Automotive Ethernet link:
–Link (Green): Turns on when the 100BASE-T1/Ethernet Media Converter is
connected to an active Automotive Ethernet device and remains on as long as
the link is maintained.
–Err (Red): Flickers upon detection of an error by the 100BASE-T1/Ethernet
Media Converter's BroadR-Reach (100BASE-T1) PHY, such as detecting a data
transmission error in a received frame.

–Rx (Green): Flashes when receiving data by the 100BASE-T1/Ethernet Media
Converter from the connected Automotive Ethernet device.
–Tx (Green): Flashes each time when transmitting data by the 100BASE-T1/
Ethernet Media Converter to the attached Automotive Ethernet device.
Under normal circumstances, you will see the Link LED always on, with the Rx and
Tx LEDs flashing at different rates depending on how much data is being sent by
each device connected to the 100BASE-T1/Ethernet Media Converter. Assuming
that all devices are functioning correctly, the Err LED should rarely, if ever, light
up.
BroadR-Reach (100BASE-T1) Connector Pinout
Refer to Table 2-1 for the pinout of the 100BASE-T1/Ethernet Media Converter's
Molex Mini50 jacks, with the pin numbers shown in Figure 2-4.
Pins are numbered 1 to 4 from left to right looking at the jack shown in Figure 2-4.
