1 Feature List
The Technica Engineering 1000Base-T1 SPY mini samples 1000Base-T1 Frames directly on
the bus without influence of the original network. The data Frames are enhanced with addi-
tional in-formation as an exact timestamp and the bus port which 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.

5 Configuration
The 1000Base-T1 SPY mini is configured by 8 DIP Switches on the front of the device.
DIP Switch 1:
ON
= 1000Base-T1 Port 1 is set to Master.
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 infor-
mation.
DIP Switch 5:
Enable wrapper.
DIP Switch 6 to 8:
Frame Generator configuration
Note: After changing switches 1 and 2, a hardware reset is not required. These switches can
be changed on real time. After changing the rest of the switches, a hardware reset is re-
quired.
Note: The Frame Generator functionality is not available on this firmware version.

6 Use Cases
Four different Use Cases can be configured by DIP Switch 3 and 4 for the 1000Base-
T1_SPY_mini. After changing these 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” (both switches down). The 1000Base-T1 Spy mini will act similar to 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.
Figure 4: Dual MediaConverter Mode

Page 11 of 21
6.2 Spy Mode Independent
The user can select this mode by setting the DIP switches 3 and 4 to “01” (DIP Switch 3
down and DIP Switch 4 up).
In this mode the copied data from the two 1000Base-T1 Ports are logged independently
through the 2 Ethernets ports. There is no communication from Ethernet to 1000Base-T1.
The RJ45 Ports are output only. The communication between the two 1000Base-T1 ports is
possible.
This mode is very powerful in combination with the TimeStamp Feature (see Chapter
6.4., Spy Mode with wrapper).
Figure 5: SPY Mode independant

Page 12 of 21
6.3 Spy Mode Combined
The user can select this mode by setting the DIP switches 3 and 4 to “10” (DIP Switch 3 up
and DIP Switch 4 down).
In this mode 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 each 1000Base-T1 Port.
In the Spy 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 pos-
sible.
This mode is very powerful in combination with the TimeStamp Feature (see Chapter 6.4,
Spy Mode with wrapper).
Note: This mode, in combination with the Wrapper mode (see Chapter 6.4) activates the
802.1AS Synchronization on the device (see Chapter 6.5).
Figure 6: Spy Mode combined

Page 13 of 21
6.4 Spy Mode with wrapper
The user can activate the wrapper by setting the DIP Switch 5 to the up position. With this
feature, 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 PY 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 byte in the preamble field of
a frame was 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.

6.4.1 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 available on Technica Engineering website. To install the LUA file in Wireshark,
the user has to do the following steps:
Figure 8: Screenshot of 1000BASE-T1_SPY_mini frame

Page 15 of 21
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:
https://technica-engineering.de/produkt/1000base-t1-spy-mini/
https://technica-engineering.de/wp-content/uploads/2018/06/1000Ba-
seT1_SPY_Mini_Wireshark_Dissector.zip
3. Extract the downloaded ZIP file. This file should contain the following LUA file:
1000BaseT1_SPY_Mini_ETH_wrapper.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 the
PC
5. 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
6. To copy or move the LUA files
to the specified Wireshark
plugins folder, Administrator
rights will be needed. In that
case, this window should
appear. Press Continue to
proceed with the copy.
7. Run Wireshark.

6.5 802.1 AS Synchronization
When the user selects the SPY Combined Mode -see Chapter 6.3- with the Wrapper enabled
-see Chapter 6.4-, the 802.1AS Synchronization is automatically enabled.
With this functionality, the device will be able to synchronize with any Master Device. In this
case, the device will use the same TimeStamping as the Master Device, and this includes
the maintenance of synchronized time during normal operation and following addition, re-
moval, or failure of network components and network reconfiguration.
6.5.1 802.1 AS Protocol
In a 802.1AS topology, the communication
between a Master and a Slave Node is as
you can see in the picture to the right.
For a generic time tx, the Slave device can
correct this time as follows:
tx‘ (ns) = tx + t1 + t2 + ∆t - Path Delay
With t3, t4, t5 and t6, the slave device can
calculate the Path Delay as follows:
𝑃𝑎𝑡ℎ𝐷𝑒𝑙𝑎𝑦 (𝑛𝑠)=(𝑡6 − 𝑡3)− (𝑡5 − 𝑡4)

6.5.2 802.1 AS in 1000Base-T1 SPY Mini
The 1000Base-T1 SPY Mini device
works only as a Slave device, sending
Request messages to the Master de-
vice through GB2 port.
Connecting a Master Device to this
port, the device will synchronize its in-
ternal clock and it will use this cor-
rected clock as Timestamping on the
Wrapper Mode. If this functionality is
not enabled, or the Master device is
not connected to the GB2 on this work-
ing mode, the device will use its inter-
nal clock as Timestamping, without
correction.

7 Frequently Asked Questions – FAQ
Q: What is the delay time for Ethernet packets between two 1000Base-T1 ports?
A: For the SPY mode -independent or combined-, the delay between two BroadR-Reach
ports is around 1.19µs. 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 must be set to
SPY Use Case. When using automotive AVB profile the time synchronization is not influ-
enced by the SPY.
There is no special handling of AVB frames as this is not necessary.
Q: The FPGA or Host LEDs are not toggling as is described on the Chapter 4 of this
User Manual. What is going wrong?
A: There is a problem on the device. Please, remove the power supply and restart the board.
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 Priority
& VLAN. If this option is enabled, just disabled. Otherwise, it should be enabled.
Q: Is this device running with 100BASE-T1 connection?
A: No 100BASE-T1 support. Device is only for 1000BASE-T1 suitable
