OFF = 1000Base-T1 Port 1 is set to Slave.

DIP Switch 2: ON = 1000Base-T1 Port 2 is set to Master

OFF = 1000Base-T1 Port 2 is set 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.

6 Use Cases Different Use Cases can be configured with the DIP Switches 3 and 4 for the 1000Base-T1 SPY mini. After changing these switches, a hardware reset is required.

6.1 Dual Media Converter Mode

UseCase “00”: Dual Media Converter Mode

The simplest Use Case is the double Media Converter, selected by setting the DIP switches 3 and 4 to “00” (both switches down). The 1000Base-T1 SPY mini will function like completely independent Media Converters from 1000Base-T1 to Gigabit Ethernet in full-duplex mode.

The two data streams of the two Media Converters are completely independent of each other. 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 Gigabit Ethernet (1000 Mbit/s) Mode in this Use Case.

of 24

6.2 Spy Mode Independent UseCase “01”: Spy Mode Independient.

In this Use Case, the copied data from the two 1000Base-T1 Ports are logged independently in the in the 2 ethernets ports. The PC is not able to send data. The RJ45 Ports are output only. The communication between the two 1000Base-T1 ports is possible.

of 24

6.3 Spy Mode 2 in 1

UseCase “10”: Spy Mode 2 in 1

In this Use Case the copied data from the two 1000Base-T1 Mbit/s are logged into one 1000Mb/s stream and are sent on one Gigabit link. To do a collision resolution the packets are buffered on the 1000Base-T1 Port.

In this mode, the signals received in 1000Base-T1 Port 1 and 1000Base-T1 Port 2 are combined in one stream and sent on Ethernet Port. The PC is not able to send data. The RJ45 Ports are output only. The communication between the two 1000Base-T1 ports is possible.

This UseCase is very powerful in combination with the TimeStamp Feature (see Chapter 6.2.2.):

6.4 Spy Mode Independent with Wrapper

UseCase “11”: Spy Mode Independient with Wrapper (TimeStamp Feature)

In this case, a header is added on the Ethernet sent frame. The packet received in the 1000Base-T1 port will be logged through the corresponding Ethernet Port into an Ethernet RAW frame. The following picture shows the structure of an Ethernet 1000Base-T1 SPY 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 synchronous to all connected lines.

With this feature the user can record the exact time when the first bytes of a frame were received on a 1000Base-T1 port of the 1000Base-T1 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

Note: The following table shows the values of Port field:

6.5 1000Base-T1 SPY mini LUA Dissector Installation Guide In order to dissect the 1000Base-T1 SPY 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.

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:

Gigabit_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).

Note: Wireshark Version Number depends on the Wireshark version installed on

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.

6.6 Frame Generator Mode In this case, the device works as a Frame Generator, sending Ethernet frames on GB1 with Gigabit Speed and on all 2 1000Base-T1 ports with 1000Mbit/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 sequences 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 switch allows to select the Framerate:

o DIP Switch 7 OFF, DIP Switch 8 OFF (“00”): 5 MBit/s o DIP Switch 7 OFF, DIP Switch 8 ON (“01”): 50 MBit/s o DIP Switch 7 ON, DIP Switch 8 OFF (“10”): 90 MBit/s o DIP Switch 7 ON, DIP Switch 8 ON (“11”): 98 MBit/s

These rates are used in all 1000Base-T1 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.

6.7.1 Frame Format

The following image shows the Frame Format transmitted on all 1000Base-T1 ports and GB port in Frame Generator Mode.

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:

6.7 Status Reporter On any of the 1000Base-T1 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 two times, one per 1000Base-T1 port, giving information about the communication status in every single port.

8 Frequently Asked Questions – FAQ

Q: What is the delay time for Ethernet packets through the SPY?

A: The delay time depends on the UseCase that is set. For SPY Mode without wrapper the delay is around 12µs. For Media Converter Mode, the delay is around 2.8µs. This delay is independent of the Ethernet packet frame size.

Q: What is the delay time for Ethernet packets between two 1000Base-T1 ports?

A: For the Media Converter Mode, the delay between 1000Base-T1 ports is around 1.5µs. The delay is independent of the Ethernet packet frame size.

Q: Is AVB supported?

A: The SPY is especially built for testing AVB. For minimum delay the SPY has to be set to SPY Use Case. When using automotive AVB profile the time synchronization is not influenced by the SPY.

There is no special handling of AVB frames as this is not necessary.

Q: The 1000Base-T1 Link LED is lit but I have no valid Link. What is going wrong?

A: There is a bug in the used 1000Base-T1 PHY. When the 1000Base-T1 Plus and Minus lines are swapped, and the SPY Port is set to 1000Base-T1 Slave then the Link LED is lit, but there is no data trans-mission possible. So please connect the 1000Base-T1 lines preoperly.

Q: I am not able to see any packet in Wireshark in SPY -with or without wrapper- mode. What is going wrong?

A: Some Ethernet Adapters must have the VLAN & Packet Priority option disabled. Please,

change this configuration, going to Ethernet Adapter Properties/Advanced/Packet Priori-ty &

VLAN. If this option is enabled, just disabled. Otherwise, it should be enabled.
