2Introduction
The Media Converter realizes a bi-directional network connection between 100BASE-T1 (BroadR-
Reach) and 100BASE-TX (Fast Ethernet) physical layer. The converter easily connects devices with a
standard OPEN Alliance BroadR-Reach (OABR) port, such as automotive cameras or ECUs, to a standard
computer network.
The device establishes a point-to-point link between an unshielded twisted-pair OABR port and
a Fast Ethernet port. The converter features one DSUB9 (BroadR-Reach, CAN bus), one Fast Ethernet

port with RJ-45 connector, and a Micro-USB connector (Chapter 4.1). The OABR channel is configurable
as either Master or Slave by a switch button or programmatically, and the device can be powered
either via DSUB connector or via USB. (Chapter 4.2)
The converter offers a possibility to access SMI registers of both transceivers (PHYs) via a CAN bus or a
USB’s virtual serial port. (Chapter 4.3) This enables the user to evaluate signal strength, detect polarity
of the T1 port, carry out a BroadR-Reach media test to diagnose cable errors, fine-tune the PHYs
parameters, and generally to read and write the registers.
2.1 Features
•Physical Layer conversion between 100BASE-T1 and 100BASE-TX
•Master / Slave configuration for OABR
•Automatic polarity detection for Slave
•6 Status LEDs
•Powered via DSUB9 or Micro-USB connector

4Device Description
4.1 Overview
The converter has three connectors, six LEDs (4 on top, 2 on RJ-45 connector), two DIP
switches and a reset button.
4.2 Power
The device can be powered over CON 1: pins 3 and 9 or over CON 2: USB Type –B. See Chapter
4.8 for information on galvanic isolation.
Figure 4 Power Options
4.3 Media Conversion
Connect 100BASE-T1 network over CON1 (DSUB9M) pins 4 (BP - Positive) and 5 (BM -
Negative). Connect 100BASE-TX (Fast Ethernet) network over CON2 (RJ-45). Do not forget to select
the select T1 Master/Slave configuration depending on your use case (Chapter 4.4.2), and to power
the device (Chapter 4.2).

Both RJ-45 and Micro-USB connectors use the standard pinouts. From left on RJ-45 port is
yellow and green LED. RJ-45 connector is galvanically isolated (Chapter 4.8). USB can be used for
diagnostic purposes (Chapter 5.2). The 100BASE-T1 Media Converter forwards Ethernet
communication packets between 100BASE-T1 and 100BASE-TX ports only.

Table 4 LED Function Description
4.6 CAN Bus Termination
Status information of the 100BASE-T1 Media Converter can be obtained over USB or CAN bus.
In case of a CAN bus connection, there is no internal termination resistor inside the device. Therefore,
a proper termination of the CAN bus is needed. The user needs to make sure the CAN bus is properly
terminated at both ends.
Figure 7 CAN Bus Termination
4.7 Factory Reset
The reset button is located on the side of the device (see Figure 3). For resetting to factory
defaults, power the device, wait a few seconds and then press and hold the button for 10 seconds. The
button can be pressed by tweezers or a pencil.
4.8 Galvanic Isolation
The Fast Ethernet (RJ-45) port is the only port of the device with galvanic isolation. Please be ware
that if you for example connect the device to a PC over USB, the ground signal of T1 link will be
connected to the USB port’s ground.

5Usage
The Media Converter offers a plug&play bi-directional connection between 100BASE-T1 and
100BASE-TX port. USB and CAN bus can be used for diagnostic purposes.
5.1 100BASE-T1 to 100BASE-TX Conversion
Purpose of the device is to inter-connect 100BASE-T1 (BroadR –Reach) and 100BASE-TX (Fast
Ethernet) physical layers.
Power up the Media Converter as described in Chapter 4.2. The green Power LED will light up.
Select T1 Master/Slave mode as desired - either by hardware (set the Master/Slave DIP switch
to ON or OFF) or by software (Chapter 5.2).
Connect your Fast Ethernet network to the RJ-45 connector. Yellow and green LED on RJ-45 is now in
state “On”. Yellow LED on RJ-45 port and green LED on T1 Link Act flashes, when is a communication
packet received.
When USB is connected to the computer, the Green LED on CAN/USB is enabled.
5.2 Diagnostic over USB
When connect the media converter to PC over USB, it will be enumerated as a virtual COM port.
Windows 10 operating system and newer is supported.
The 100BASE-T1 Media Converter Utility PC application allows to read the status of the device.
The utility can be downloaded from www.machsystems.cz/en/support .
Run “100BASE-T1 Media Converter.exe”. Now you see window of Windows application as
shown below. To start monitoring, click once on button „Connect“.
