# NWIN002 2xPt100 temperature
The NWIN002 node has connectors for two 4 wire Pt100 sensors and can be battery or battery and DC powered.
* The green connectors for Pt100 4 wire sensors (marked 1 for index 0 and 2 for index 1 sensor) can be disconnected by pulling them upwards away from the circuit board. The sensor wires shall be screwed tight to the connector to minimize the connection resistance. The 2 pairs of wires from two sides of 4 wire PT100 sensor shall be connected to left and right pairs of pins of the sensor connector respectively. If a sensor with 2 or 3 wires is used, then the not used connector pin must be shorted with its pair. It is not recommended to use 2 or 3 wires sensors because the wires resistance will not be compensated which will introduce the measurement error.
* There is a holder for 2 AA batteries.
* A DC jack (5) is used to supply the node from an external 9-12 V power supply.
* There is a send and reset button (4) on the left side of the board. Please make sure that no cables can press this button.
* A transmission LED (3) is in the top left corner of the board. It blinks every time the node sends data to the gateway.
* The blue hinge can be removed for easy routing of cables as described in [Enclosure opening](/win-gateway-installation-manual/mechanical-installation/enclosure-opening.md).
* The cable slot is used to route the sensor cables as described in [Cables routing](/win-gateway-installation-manual/mechanical-installation/cables-routing.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://help.boomerang3.com/win-gateway-installation-manual/infrastructure/win-node-types/nwin002-2xpt100-temperature.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
