sleep

Usage

>> sleep

Security

Open.

Description

Immediately shuts down communications and implements any power saving measures which are possible, over-riding the 10-second timeout which normally invokes these actions (see Section Timeouts, output blanking, and power saving). Power saving measures typically include:

Any interface circuitry used for a Serial link.
Sensor channels activated only for the purpose of satisfying a poll command.

Any scheduled sampling activity is not affected. The sleep command does not attempt to power down a USB link, because there is always enough power available via USB to run the logger's basic functions; sensor channels used for a poll command will still be shut down.

If settings confirmation=on then the the sleep command will provide a confirmation response prior to performing the power saving measures, otherwise no response is expected.

Examples

TEXT

>> settings confirmation
<< settings confirmation=off

>> sleep
% No response after issuing the sleep command

The sleep command is issued with the confirmation state = off. The instrument will not respond and will immediately move into a low power state.

TEXT

>> settings confirmation
<< settings confirmation=on

>> sleep
<< sleep

The sleep command is issued with the confirmation state = on. The instrument will respond with the command prior to moving into a low power state.
