# Connecting the Device

{% hint style="danger" %}
**Attention:**

* A qualified technician must install, connect, and commission the device.
* Ensure the power supply is disconnected before connecting the device.
* Please do not use the logger's USB port for data logging, as it may damage the port and will not be covered under warranty.
* Only use components from the starter kits or the accessories supplied.
  {% endhint %}

### POWER

Power supply to the product is provided via the male, 9-pin D-type connector.

{% hint style="warning" %}
**Notes:**

* The connector needs to be adequately tightened to ensure a reliable connection and proper operation.
* Do not short-circuit any pins.
* The maximum safe applied voltage is +34V.
  {% endhint %}

### CAN

ReXgen 1 can be interfaced to the CAN bus, from which data will be logged using D-Sub 9. The CAN-high and CAN-low from the vehicle or machine terminals must match the CAN-high and CAN-low terminals of the ReXgen1. ReXgen1 should be configured with the same baud rate as the device to which it is interfaced.

{% hint style="danger" %}
**Warning:**

* The connector needs to be adequately tightened to ensure a reliable connection and proper operation.
* Each end of the CAN bus must be terminated with a 120Ω resistor across CAN H & CAN L.
* Do not short-circuit any pins.
* The maximum safe applied voltage is +28V.
* CAN bus is not isolated by default; isolating devices can be purchased separately.
* Please do not use the logger's USB port for data logging, as it may damage the port and will not be covered under warranty.
  {% endhint %}

### USB

A USB cable can be used to interface with and power the device as a PASS-THRU device. It will configure the device for data retrieval as a data logger.

{% hint style="warning" %}

#### Attention:

* Please do not use the logger's USB port for data logging, as it may damage the port and will not be covered under warranty.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.influxtechnology.com/support_guides/rexgen-series-product-manuals/rexgen-1/rexgen-1-product-manual/getting-started/connecting-the-device.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
