# HW Info Tool

The user application can transmit a CAN Message to ReXgen to trigger the following responses:

1\) Current Firmware version of the ReXgen.

2\) ReXgen should confirm that it is configured, has a configuration version, and has an active configuration.

3\) Send the serial number of the ReXgen.

4\) Send the RTC Date & time.

####  Format of the Transmitted message:

<table data-header-hidden data-full-width="true"><thead><tr><th width="165"></th><th width="123"></th><th width="123"></th><th></th><th width="108"></th><th></th><th></th><th width="106"></th><th></th></tr></thead><tbody><tr><td><strong>Function</strong></td><td><strong>Request ID</strong></td><td><strong>Transmit ID</strong></td><td><strong>0</strong></td><td><strong>1</strong></td><td><strong>2</strong></td><td><strong>3</strong></td><td><strong>4</strong></td><td> </td></tr><tr><td><strong>Firmware</strong></td><td>RX Ident</td><td>Tx Ident</td><td>FW_MAJOR_VERSION</td><td>FW_MAJOR_VERSION</td><td>FW_MINOR_VERSION</td><td>FW_BRANCH</td><td> FW_TYPE</td><td></td></tr><tr><td><strong>Configuration ID</strong></td><td>RX Ident +1</td><td>Tx Ident +1</td><td>Configuration Version Number</td><td> Configuration Version Number</td><td>Configuration Version Number</td><td>Configuration Version Number</td><td></td><td></td></tr><tr><td><strong>Manufacturing INFO</strong></td><td>RX Ident +2</td><td>Tx Ident +2</td><td>Product</td><td>Assembly</td><td>Batch</td><td>Batch</td><td> SERIAL_NUMBER</td><td></td></tr><tr><td><strong>RTC Time</strong></td><td>RX Ident +3</td><td>Tx Ident +3</td><td>UNIX Date/Time</td><td>UNIX Date/Time</td><td>UNIX Date/Time</td><td>UNIX Date/Time</td><td></td><td></td></tr></tbody></table>

Allows to drag and drop the same into the configuration. The tool has the following settings:

* Output CAN
  * Users can choose CAN 0 or CAN 1
* **Rx Ident:** Start range CAN ID of messages transmitted from an external tool.
* **Tx Ident:** Start range CAN ID of messages transmitted from ReXgen.

#### Example:

If Rx Ident is 7E0 and TX Ident is 7E8 in the configuration, the Identifiers will be as shown below:

| **Rx Ident** | **Tx Ident** | **HW Info**               |
| ------------ | ------------ | ------------------------- |
| 7E0          | 7E8          | Firmware                  |
| 7E1          | 7E9          | Configuration ID          |
| 7E2          | 7EA          | Manufacturing Info        |
| 7E3          | 7EB          | RTC Time (UNIX Date/Time) |

# 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/rexdesk-configuration-software-s/rexdesk-rexgen-series-configuration-software/rexdesk-manual/software-introduction/configuration-panel/transmitting/hw-info-tool.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.
