Turn off ELS31-VA/ELS51-VA

To switch the module off the following procedures may be used:
•

Software controlled shutdown procedure

: Software controlled by sending an AT command

over the serial application interface. See

Section 3.2.4.1

.

•

Hardware controlled shutdown procedure

: Hardware controlled by employing the

FST_SHDN line. See

Section 2.1.16.4

.

•

Automatic shutdown (software controlled)

: See

- Takes effect if ELS31-VA/ELS51-VA board temperature exceeds a critical limit.

3.2.4.1

Switch off ELS31-VA/ELS51-VA Using AT Command

The best and safest approach to powering down

ELS31-VA/ELS51-VA

is to issue the appropriate

AT command. This procedure lets

ELS31-VA/ELS51-VA

log off from the network and allows the

software to enter into a secure state and safe data before disconnecting the power supply. The
mode is referred to as Power Down mode. In this mode. Before issueing the switch off AT com-
mand, the ON signal should be set to low (see

). Otherwise there might be back pow-

ering at the ON line in Power Down mode.

While

ELS31-VA/ELS51-VA

is in Power Down mode the application interface is switched off and

must not be fed from any other voltage source. Therefore, your application must be designed
to avoid any current flow into any digital pads of the application interface.
