ReXgen Sleep/Wake up function Implementation

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).”

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

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

Notes:

• The logger will wake on CAN 0 and CAN 1 when Deep Sleep Mode is used.

• The logger will not wake up from this mode on connecting USB

Normal Sleep

Normal sleep mode with a power consumption of 25 mA.

a) Wake On CAN Options:

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.

Notes:

• Users can enable both options so the logger will wake on CAN 0 and CAN 1.

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.

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

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

Notes:

• The User can combine all the options so the logger will wake on CAN 0/CAN 1/Alarm.

c) Wake Up On Movement* Option:

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

Note:

• Available only in ReXgen Air Devices.
