NB3D Quick Start Guide
NB3D Device Activation
The NB3D is shipped in Flight Mode and should be activated as part of the installation process.
Every time a device is installed, it will need to be Activated or Swiped via the Magnet or NFC swipe as described below. This, in conjunction with the Survey - Swipe guide, will show if the device is configured and working correctly in the field.
Please note that the locations for the Magnet and NFC swipe are different than the other Taggle device models with the same form factor.
Please ensure you perform the swipe correctly and receive a valid response before completing the installation.
Activation with Magnet
Swiping with a strong magnet under the label near the base of the device will trigger an instantaneous transmission from the device over a 15 second period. It will also ‘Activate’ the device to begin transmitting from its configured interval ( if the NB3D is not a connectorised variant).
For the connectorised variant, the sensor cable attached and correctly wired to the M12 plug.
Note: If the sensor is a 2-wire sensor, then Pin 1 and Pin 3 must be connected, otherwise the NB3D cannot exit FLIGHT MODE.
Please note the direction of the swipe as per the image.
Activation with NFC
Activating the NFC unit by tapping once with an NFC reader or capable device over the area just above the label in the middle of the device will triggers an instantaneous transmission from the device over a 15 second period. It will also ‘Activate’ the device to begin transmitting from its configured interval ( if the NB3D is not a connectorised variant).
For the connectorised variant, the sensor cable attached and correctly wired to the M12 plug.
Note: If the sensor is a 2-wire sensor, then Pin 1 and Pin 3 must be connected, otherwise the NB3D cannot exit FLIGHT MODE.
When activating the NB3D with a NFC capable device with an app, you will be able to see that the device has the status OPERATIONAL when it is successfully activated.
See also the Where to Swipe Taggle devices knowledgebase article.
Taggle Survey Tool
An installer can trigger a burst of transmissions from the NB3D device using the procedure described above.
The installer can monitor the receptions from these transmissions using the Survey - Swipe section of the Taggle Data Portal.
More information and comprehensive instructions for the Taggle Data Portal can be found at Taggle Data Portal User Guide.
NB3D Wiring Diagrams
For the connectorised version of the NB3D, the M12 plug can be wired to suit different devices.
M12 Sensor Plug
The NB3D is supplied with a 5 pin M12 plug as shown. Note the centre pin (Pin 5) is not used.
When inserting the sensor cable through the rear gland in the plug attention should be placed to achieve a watertight seal. Sealing tape may be needed to thicken the cable outer diameter to ensure a watertight seal.
Replacement plugs are available from Taggle.
Sensor cable must be between 4mm and 8mm in diameter to ensure proper seal within the plug to prevent water entering and contacting the terminal block.

Commercial and Industrial (C&I) Meters
Most C&I meters have an option to provide a passive pulse output, and some meters can also provide a direction output. The passive outputs (sometimes referred to as “Open Collector” or “Open Drain” outputs) are usually implemented as a transistor switch to Ground. The exact markings of the outputs vary from different manufacturers but in general the ground side of the switch is usually marked as ‘-‘ and the high side marked ‘+’
Note the Tamper, Pulse, and Direction inputs have an internal pull-up resistor, and no additional external pull-up resistor is required.
For bi-directional meters the direction status must be logic high for forward flow and logic low for reverse flow. This implies that the output should be programmed to be in the ‘on’ or ‘energised’ state for reverse flow, as this will ground the direction input to the RTU.

3 | Ground | Pulse (-) and link from pin 1 |
4 | Direction | Not connected |
5 | None | Not connected |
2-wire devices must connect pins 1 and 3 to close the tamper loop.
