# ReXgen Sleep/Wake up function Implementation

<figure><img src="/files/p4mrXSKe1mJByKwX8qGT" alt=""><figcaption></figcaption></figure>

The logger goes to sleep mode when both the CAN bus become inactive.

Following are the triggers that can wake the logger when it is in Deep/Normal Sleep Mode:

| **Wake UP Options** | **Deep Sleep(1mA)** | **Normal Sleep (25mA)** |
| ------------------- | ------------------- | ----------------------- |
| USB                 |                     | Yes                     |
| CAN0                | Yes                 | Yes                     |
| CAN1                | Yes                 | Yes                     |
| ALARM               |                     | Yes                     |
| ACCELEROMETER\*     | Yes                 |                         |
| CLAMP/ERASE PIN\*   | Yes                 |                         |

*\*Will be enabled in the next quarter.*

## Power Consumption.

* Deep Sleep: 1mA.
* Normal Sleep: 25 mA

The sleep delay is specified in the “Sleep after no CAN activity for (minutes).”

&#x20;Three types of sleep modes are available:

* No sleep
* Deep Sleep
* Normal Sleep

### No Sleep

ReXgen will not use the Sleep/Wakeup function when ‘No Sleep’ is selected.

### Deep Sleep

Deep sleep mode with a power consumption of 1 mA

<div align="left"><figure><img src="/files/cuEJVTXQYFBtW2lwcPzb" alt="" width="361"><figcaption></figcaption></figure></div>

* Enable ‘Wake Up On Movement’ to wake up the logger on movement.

{% hint style="info" %}

#### Notes:

* 'Wake Up On Movement' is available only in ReXgen Air Devices and above.
* The logger will wake on CAN 0 and CAN 1 when Deep Sleep Mode is used.&#x20;
* The logger will not wake up from this mode on connecting to USB
  {% endhint %}

### Normal Sleep

Normal sleep mode with a power consumption of 25 mA.

#### a) Wake On CAN Options:

<div align="left"><figure><img src="/files/fPzIP8SQcuYd7sv847Xn" alt="" width="311"><figcaption></figcaption></figure></div>

1. **Wake Up On CAN 0:** The logger will wake up from sleep mode when CAN activity is on the CAN 0 Bus.
2. **Wake Up On CAN 1:** The logger will wake up from sleep mode when CAN activity is on the CAN 1 Bus.

{% hint style="info" %}

#### Notes:

* Users can enable both options so the logger will wake on CAN 0 and CAN 1.
  {% endhint %}

#### b) Wake On Alarm Option:

* **Wake Up Once:** The logger will wake up from sleep mode once on the specified date at the specified time.

<div align="left"><figure><img src="/files/ePFL6SbN3DaqkYQShh9K" alt="" width="308"><figcaption></figcaption></figure></div>

* **Wake Up Everyday:** The logger will wake up from sleep mode at a specified time every day.

<div align="left"><figure><img src="/files/0KuuYy1fhRZoupvJQNEi" alt="" width="308"><figcaption></figcaption></figure></div>

* **Wake Up Minutes after Sleep:** The logger will wake up from sleep mode after the specified time in minutes.

<div align="left"><figure><img src="/files/KKbovXrhMIbFEGOHzbIK" alt="" width="312"><figcaption></figcaption></figure></div>

{% hint style="info" %}

#### Notes:

* User can combine all the options so the logger will wake on CAN 0/CAN 1/Alarm.
  {% endhint %}

#### c) Wake Up On Movement\* Option:

The logger will wake up from sleep mode once any movement is detected.
