How to update the Firmware


  1. Do not connect Pockethernet to the USB port yet!
  2. Download the zip package and extract it to any folder
  3. Driver installation for Windows 7 and 8 only: Open the folder in a Windows file explorer, right click "Pockethernet Driver Beta.inf", select "Install". Confirm installation. (No actual driver binary needs to be installed, the inf file only instructs Windows to use its built-in USB CDC serial driver with Pockethernet) Windows 10 already has the necessary driver built-in.
  4. Start the application, "Pockethernet Firmware Updater vXY.exe" (Needs the .NET framework 4 installed)
  5. Connect Pockethernet to the USB port
  6. The firmware updater should recognize the device and show its serial number and current SW version
  7. Click the 'Start Update' button
  8. during the upgrade process, all 4 wire-pair LEDs turn blue. After a succesfull upgrade, the LEDs turn green (or red if there was a failure during the upgrade)
  9. Once the update has finished, disconnect Pockethernet from the USB port


The updater is a single 64-bit executable, also containing the firmware image for the device
  1. Download the archive file
  2. Extract the file 'pockethernet-XYy-fwupgrade'. If needed, make it executable ($ chmod +x pockethernet-vXY-beta-fwupgrade)
  3. Plug in Pockethernet to the USB port and check dmesg or the system log to see which tty device it has been assigned (usually /dev/ttyACM0)
  4. Run the updater with "./pockethernet-vXY-beta-fwupgrade /dev/ttyACMx"
  5. During the upgrade process, all 4 wire-pair LEDs turn blue. After a succesfull upgrade, the LEDs turn green (or red if there was a failure during the upgrade)

The app - Test View


The wiremap test determines (by transmitting signals through each wire) if a pin on a connector is connected to the correct pin at the other end.

Status Possibe Faults
Miswired Damaged connector / Cuts or breaks in cable / Wires connected to wrong pins at connector or punch block
Short Circuit Improper connector termination / Damaged Connector / Conductive material stuck between pins at a connection / Damage to cable
OK There's a connection to the wiremap-Adapter

The graphical wiring diagram shows the status of each individual wire: the corresponding connected pin is shown on the right side. In case of short circuits between the wires, these are shown with a red vertical connection, opens are shown in the middle as a break in the line.

The pair numberings and colors are based on the TIA colour scheme selected in the tools -> settings menu.


This test verifies the presence of a Power over Ethernet supply in mode A (pairs 2+3/Endspan) or mode B (1+4/Midspan) and reports the voltage measured. Additionally, voltages are also measured on each wire pair separately (e.g. pins 1+2, 3+6,...) to detect the presence of analog phone lines.

The PoE results - if present - are shown in the main summary line of the measurement, the individual pairs in a table below.

The TDR-based, single ended length measurement and fault locating tests the physical properties of a cable, with just one end connected to Pockethernet. See how long the cable is and if there are any short circuits, split pairs or bad terminations. Pockethernet also detects if the cable is connected to a switched off computer or switch.

The main status line shows the overall result of the measurement if each pair in the cable is terminated the same way (e.g. all pairs are open or connected)

Status Possibe Faults
Open Cable is not connected to anything
Short Circuit There's a short circuit somewhere in the cable
Connected to ETH port Cable is connected to a Ethernet port
Bad Termination There's a bad termination. The cable might be connected to a broken ethernet device/bad cableing installation

Graphical TDR

This features allows you to measure the imperfections of a cable along its whole length or a section of it. A short electrical pulse is sent down the cable, which is reflected from imperfections (short circuits, split pairs, impedance mismatches, open ends) or absorbed by proper termination (another ethernet port). The cable is measured from its beginning until the distance that is set by the slider. For a distance up to 30 meters / 100 feet, a high-resolution plot is conducted. The maximum distance is 300 meters / 1000 feet.

On the plot graphics, the horizontal axis shows the distance, while the vertical axis shows any reflections of the initial test pulse. The 4 color lines correspond to the 4 wire pairs in the cable according to the TIA settings. Short circuits show up as a negative reflection, open ends as a positive one, while with a proper termination the graph is completely flat.

Small imperfections in the +/- 10 range can be caused by cable extenders or patch panels, which can be conveniently detected by this feature.

This test determines if an ethernet link can be established, what the highest achievable speed is. The result is shown in the summary line: 10 / 100 / 1000 Mbit, Full Duplex / Half Duplex, MDI / MDI-X.

On gigabit links, additional information is shown: The delay skew of each pair (maximum allowed per IEEE specification is 45ns) and the polarity of each wire pair, which helps detecting any wiring errors.

Succesfully established a link


When activated, Pockethernet waits for up to 65 seconds after link establishment to receive CDP or LLDP packages.

These diagnostic packages contain information about the connected switch or router, like the physical port ID Pockethernet is connected to, the system name or management IP address. Information fields, called TLVs of the received packet are listed in the details section of this measurement.

VLAN tag

By activating this option, you can set up Pockethernet to use 802.1q VLAN tagging for any outgoing packet of DHCP requests or pings.

This allows you to test the network connectivity on a specific VLAN (ID), while also defining the packets priority (PCP: 0-7) and the Drop eligible indicator (DEI).

DHCP / static IP

This section allows you to test the networks DHCP settings and make Pockethernet request its IP configuration via DHCP, or you can set up static IP settings to be used for the ping tests.

In case of DHCP, the DHCP offer from the server is parsed and all important fields (e.g. server IP and MAC address, lease times, further servers) are listed in the details.

DHCP results


You can enter up to three IP addresses or domain names to be pinged.

The results include the pinged IP address (so that this test can also be used for DNS resolution) and the average ping time of 3 measurements.

The traffic sampling feature allows you to see samples (i.e. not all packets are forwarded to the APP) of the network traffic. Pockethernet will wait for 60 seconds and forward some of the the incoming packets to the app, where the destination and source MAC address are displayed along with any VLAN tag and the ethernet protocol/frame size field.

BER - Bit Error Rate test

The Bit Error Rate Test measures the overall quality of a cable run by sending and receiving large amount of ethernet frames and measuring how many of them get corrupted along the way.

To test different scenarios, you can configure the link speed which is used, the packets length and contents (fixed pattern of 0x5AA5 bytes or a pseudo-random sequence). The ratio of packets with CRC errors will be displayed in percent or ppm (parts per million) and is a directly proportional to the cabling quality.

The App - tools overview


The toner function allows identification and tracking of cables via an electronic signal that can be picked up with a tone probe. You can use it to identify individual cables in a bundle, identify individual wire pairs and track their path in culverts and walls. You can select on which wire pair the signal should be transmitted, which tone should be used at what volume. You can use any analogue tone probe to pick up the signal.


You can use this function to identify the ethernet port on switches and routers to which the cable is connected, by making the link LEDs blink. As a secondary function, you can manually test if a link can be established at specific speeds and duplex settings.

TDR calibration

This allows you to calibrate the TDR distance measurement and to adjust for the NVP of the currently inspected cable. As the 4 wire pairs in a cable have different twist rates and therefore different length, they can be adjusted separately.

For the calibration process, you need to connect a cable with all 4 pairs disconnected and of at least 5 meters length. Then press the Measure button, wait for the results and adjust the sliders of each pair, so that the 'Calibrated' values match the actual length of the connected cable.
