1 Feature List
The Technica Engineering BR SPY mini samples BroadR-Reach Frames directly on the bus
without influence of the original network. The data Frames are enhanced with additional in-
formation as an exact timestamp and the bus port the data was originally sent on. All data
can be recorded on a PC or datalogger for detailed offline analysis.
Timestamps are in 0.04 μs resolution and synchronous to all connected lines.
Optionally other UseCases (Frame Generator, Trigger Generator, …) can be upgraded.

3.3 RJ45 Ethernet connectors
There are two RJ45 Standard Ethernet connectors of the front side for Gigabit Ethernet.
Depending on the selected Use Case they are forced to be 100 Mbit/s or Gigabit Ports.

Page 9of 23
4 Status LEDs and Pushbutton
The BR SPY mini has several status LEDs at the front side of the case.
The “Host” LED1 must be ON, and “Host” LED2 must toggle slowly (approx. 1 sec).
If LED2 does not toggle or LED1 is OFF, an error has been detected by the Host.
The “FPGA” LED1 and LED2 show the setting of the DIP switches 3 and 4. When one of
these switches is ON, the corresponding LED is ON.
The 4 BR Link LEDs 1A to 2B monitor the link status of the ports BR1A to BR2B. The LEDs
are lit when there is BroadR-Reach link detected. These LEDs are updated in real time.
Note: There is an issue when P/N of the bus are swapped. The LED may be on in this case
on BroadR-Reach slave side, but there will be no data transmission possible.
The built-in LEDs in RJ45 connector shows the status of the gigabit ports. The left (orange
LED) is lit by a link-up. The right (yellow) will blink on data traffic.

5 Configuration
The BRSPY mini is configured by 8 DIP Switches on the front of the device.
DIP Switch 1: ON = BroadR-Reach Port 1A is set to Master Port 1B to slave.
OFF = BroadR-Reach Port 1B is set to Master Port 1A to slave.
DIP Switch 2: ON = BroadR-Reach Port 2A is set to Master Port 2B to slave.
OFF = BroadR-Reach Port 2B is set to Master Port 2A to slave.
DIP Switch 3 to 4: Use Case Selection. Binary Coded from 00 to 11.
Please refer chapter “Use Cases” in this User manual for further
information.
DIP Switch 5 to 8: Frame Generator speed, burst and packet size selection

6 Use Cases
Four different Use Cases can be configured by DIP Switch 3 and 4 for the BRSPY mini. After
changing this switches, a hardware reset is required.
6.1 Dual Media Converter Mode
The simplest Use Case is the double Media Converter, selected by setting the DIP switches
3 and 4 to “00”. The BR SPY mini will act similar to two completely independent Media Con-
verters from BroadR-Reach to Fast Ethernet in Full Duplex Mode.
The two data streams of the two Media Converters are completely independent of each oth-
er. Both data streams are full duplex and the RJ45 Ports are input/output. The PC can send
data.
There are no buffers in this Use Case.
The RJ45 Ports work in Fast Ethernet (100 Mbit/s) Mode in this Use Case.

6.2 Spy Mode
In this Use Case the RJ45 Ports work in Gigabit Mode. The copied data from the two 100
Mbit/s BroadR-Reach Ports are combined to one 200 Mbit/s stream and are sent on one Gi-
gabit link. To do a collision resolution the packets are buffered on the BroadR-Reach Port.
In the Spy Mode, the signals received in BR1A and BR1B ports are combined in one stream
and sent on GB1 port, while the signals received in BR2A and BR2B ports are combined in
one stream and sent on GB2 port.
The PC is not able to send data. The RJ45 Ports are output only.
This UseCase is very powerful in combination with the TimeStamp Feature (see Chapter
6.2.2.):
UseCase “01”: Spy Mode without Wrapper (TimeStamp Feature disabled)
UseCase “10”: Spy Mode with Wrapper (TimeStamp Feature enabled)
In this case, the communication between two BroadR-Reach ports is possible. BR1A and
BR1B ports can send packets each other, as well as BR2A and BR2B.
6.2.1 Spy Mode without Wrapper
In this case, no header is added in the sent Ethernet frame, and the received frames on the
BroadR-Reach ports are forwarded directly to the corresponding Gigabit port, without suffer-
ing any modification.

Page 13 of 23
6.2.2 Spy Mode with Wrapper
In this case, a header is added on the Ethernet sent frame. The packet received in the
BroadR-Reach port will be logged through the corresponding Gigabit Port into an Ethernet
RAW frame. The following picture shows the structure of an Ethernet BRSPY mini RAW
frame, in this use case:
Note: The data Frames are enhanced with additional information as an exact timestamp and
the bus port the data was originally sent on. Timestamps are in 0.04 μs resolution and syn-
chronous to all connected lines.
With this feature the user can record the exact time when the first bytes of a frame were re-
ceived on a BroadR-Reach port of the BR SPY mini. It is also possible to see the complete
frame including the preamble and the CRC in Wireshark. Normally this information is re-
moved by your network interface.

6.2.3 BRSPY mini LUA Dissector Installation Guide
In order to dissect the BRSPY mini RAW Ethernet Frames, a LUA file for Wireshark is avail-
able on Technica Engineering website. To install the LUA file in Wireshark, the user must
follow the following steps:
1. Close Wireshark in case that the program is running on PC.
Note: Wireshark Version Number “1.12.12” is recommended.
2. Download the .ZIP file that contains all the LUA files, through this website:
http://www.technica-engineering.de/wp-content/uploads/2017/01/BroadR-Reach-
SPY-Mini-Wireshark-Dissector.zip
3. Extract the downloaded ZIP file. This file should contain the following LUA file:
BR_SPY_Mini_ETH_wrapper_BR.lua
4. Copy or move the LUA file in Wireshark plugins folder. The path should be:
C:\Program Files\Wireshark\plugins\(Wireshark Version Number).

Page 16 of 23
Note: Wireshark Version Number depends on the the Wireshark version installed on
PC. Wireshark Version Number “1.12.12” is recommended.
5. In order to copy or move the LUA files to the specified Wireshark plugins folder,
Administrator rights will be needed. In that case, the following window should appear.
Press Continue to proceed with the copy.
6. Run Wireshark.

6.3 Frame Generator Mode
In this case, the device works as a Frame Generator, sending Ethernet frames on GB1 with
Gigabit Speed and on all 4 BroadR-Reach ports with 100Mbit/s.
In order to select this mode, the DIP switches 3 and 4 must be ON (“11” Value). In addition,
the user can select different functionalities according with the set of DIP switches 5,6,7 and
8:
•DIP Switch 5: When it is ON, it selects the Burst Mode. In this mode, the device
sends 4 packets with the minimum IFG (Interframe Gap). These sequence of packets
consists on a burst of mixed packets -a large frame and three small frames.
•DIP Switch 6: This switch selects the Packets Size. When it is OFF, the size of the
frame will be 64 bytes, and when it is ON, the size will be 1500 bytes. The sizes don’t
include the preamble and CRC.
•DIP Switches 7 and 8: This switches allows to select the FrameRate:
oDIP Switch 7 OFF, DIP Switch 8 OFF (“00”): 5 Mbits/s
oDIP Switch 7 OFF, DIP Switch 8 ON (“01”): 50 Mbits/s
oDIP Switch 7 ON, DIP Switch 8 OFF (“10”): 90 Mbits/s
oDIP Switch 7 ON, DIP Switch 8 ON (“11”): 98 Mbits/s
These rates are used in all BroadR-Reach ports, and in GB2. In Frame Generator mode, this
port will work as Fast Ethernet port, sending status frames -see section 6.3.2.
In GB1, these values are multiplied by 10.
6.3.1 Frame Format
The following image shows the Frame Format transmitted on all BroadR-Reach ports and
GB port in Frame Generator Mode.

Page 18 of 23
The frame format is fixed, and the only difference between the packets is the Stream ID field.
This field shows the port number where the frame is being sent, as it follows:

6.3.2 Status Reporter
On any of the BroadR-Reach and in GB1, the CRC and Continuous Counter fields are
checked and the result is reported each second in a Status Frame. This frame is transmitted
on GB2 with the following format:
In this port, the StreamID = 5, and the GB1 works as a Fast Ethernet port. The following im-
age shows an example of a Status Frame in Wireshark:

The following table defines the content of the Status Frame Data. These fields are replicated
four times, one per BroadR-Reach port, giving information about the communication status in
every single port.
