1GENERAL INFORMATION
1.1 Functionality and Features of the 1000BASE-T1 SPY mini
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 additional 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 Use Cases (Frame Generator, Trigger Generator, …) can be upgraded.

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 required.

4USE 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.
4.1 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 4-1: Dual Media Converter Mode

1000BASE-T1 SPY mini User Manual
14
4.2 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 4.4).
Figure 4-2: SPY mode independent
4.3 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.

1000BASE-T1 SPY mini User Manual
15
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 possible.
This mode is very powerful in combination with the TimeStamp Feature (see
CHAPTER 4.4).
Figure 4-3: UseCase "10": Spy Mode Combined
Note: This mode, in combination with the Wrapper mode (see CHAPTER 4.4) activates
the 802.1AS Synchronization on the device (see CHAPTER 5.1).

4.4 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 synchronous 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.

51000Base-T1 SPY mini LUA Dissector for wrapped
data
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 must do 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:
https://technica-engineering.de/produkt/1000base-t1-spy-mini/
https://technica-engineering.de/wp-
content/uploads/2018/06/1000BaseT1_SPY_Mini_Wireshark_Dissector.zi
p
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.
5.1 802.1 AS Synchronization
When the user selects the SPY Combined Mode (see CHAPTER 4.3) with the Wrapper
enabled (see CHAPTER 4.4)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, removal, or failure of network components and network reconfiguration.

5.1.1 PTP of 802.1 AS Protocol
In an 802.1AS topology, the com-
munication 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:
ℎ ()=(6− 3)−(5− 4)
