5 Hardware Commands

5.1 Turning ON the GE865

To turn on the GE865 the pad ON# must be tied low for at least 1 second and then

released.

When the power supply voltage is lower than 3.4V the pad ON# must be tied low at

least 3 seconds.

The maximum current that can be drained from the ON# pad is 0,1 mA.

A simple circuit to do it is:

NOTE:

Don't use any pull up resistor on the ON# line, it is internally pulled up. Using pull up

resistor may bring to latch up problems on the GE865 power regulator and improper

power on/off of the module. The line ON# must be connected only in open collector

configuration.

ON#

Power ON impulse

GND

R2

GE865 Hardware User Guide

1vv0300799 Rev.9 – 27-07-2009

NOTE:

In this document all the lines that are inverted, hence have active low signals are

labelled with a name that ends with”#" or with a bar over the name.

TIP:

To check if the device has powered on, the hardware line PWRMON should be

monitored. After 900ms the line raised up the device could be considered powered on.

NOTE:

It is mandatory to avoid sending data to the serial ports during the first 200mS of the

module startup.

GE865 Hardware User Guide

1vv0300799 Rev.9 – 27-07-2009

A flow chart showing the proper turn on procedure is displayed below:

GE865 Hardware User Guide

1vv0300799 Rev.9 – 27-07-2009

For example:

1- Let's assume you need to drive the ON# pad with a totem pole output of a +3/5 V

microcontroller (uP_OUT1):

2- Let's assume you need

to drive the ON# pad

directly with an ON/OFF

button:

5.2 Turning OFF the GE865

The turning off of the device can be done in three ways:

• by software command (see GE865 Software User Guide)

• by hardware shutdown

• by Hardware Unconditional Restart

When the device is shut down by software command or by hardware shutdown, it

issues to the network a detach request that informs the network that the device will not

be reachable any more.
