to take effect. Do not disconnect the USB port or shut the computer down during the update process. The
latest firmware is included in the ProfiShark installation folder.
Note: The ProfiShark Manager will compare the firmware of the connected device(s) with the ones included
in the installation folder every time it starts, allowing a new revision to be installed if present.
Capture Format
The Capture Format section allows users to enable or disable capture-related features. These options
apply to both Direct Capture and Live Capture modes. Additional customization of the capture process is
available in the Capture tab.
Enable timestamps in
live capture
Synchronize timestamp
(experimental)
Transmit CRC Errors
Keep CRC32
Disable Port A
Disable Port B
Packet Slicing
Appends a Unix formatted timestamp in the header of the packet data. This timestamp
can be interpreted by the Profitap Wireshark dissector in Live Capture mode.
Note: This option produces non-standard PCAP files, which require the dissector for
timestamps to be interpreted properly.
This option is ignored when using Direct Capture or Live Capture with the Extcap Tool,
both of which produce standard PCAP files with high-resolution timestamps.
Synchronizes the ProfiShark's clock speed to the clock of the host it is connected to.
When enabled, the host sends 1 pulse per second (1PPS) to the ProfiShark through
the USB port. The ProfiShark then smoothly adapts its own clock to the pulses.
This feature is useful for keeping the host clock and ProfiShark clock synchronized in
order to avoid long-term drift.
The drawback is that, since USB cannot provide high-precision timing, per-second
pulses can have a variation in the range of several milliseconds. This means that the
ProfiShark clock will change speed constantly (but not in steps, very smoothly instead).
Thus, this feature is not recommended when troubleshooting microsecond and
nanosecond delays in a short time range.
When enabled, the ProfiShark will include packets with CRC errors in the capture.
These packets are usually filtered out by network interfaces.
When enabled, the CRC32 information (32-bit Frame Check Sequence) located at the
end of the packets will be kept in the capture. FCS can be interpreted in Wireshark
(Edit \ Preferences \ Protocols \ Ethernet \ Assume packets have FCS).
If checked, frames from port A will not be captured.
If checked, frames from port B will not be captured.
ProfiShark 100M / 1G / 1G+:
The payload of every captured frame will be dropped, keeping only the header
information (the first 128 bytes) up to the application layer.
ProfiShark 10G / 10G+:
Only the specified amount of data will be captured for each frame, starting from the
beginning of the frame, specified in bytes.
