5. Hardware Commands
5.1. Turning ON the GE864-QUAD V2 / GE864-DUAL V2
To turn the GE864-QUAD V2 / GE864-DUAL V2 on, the pad ON# must be tied low for
at least 1000ms and then released. A pulse duration less than 1000ms should also
start the power on procedure, but this is not guaranteed.
The maximum current that can be drained from the ON# pad is 0,1 mA.
A simple circuit to do it is:
TIP:
TIP:
TIP:TIP:
To check if the device has powered on, the hardware line PWRMON must be
monitored. After 1000ms the line raised up the device could be considered powered
on.
NOTE:
NOTE:
NOTE:NOTE:
Do not 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 GE864-QUAD V2 / GE864-DUAL V2
power regulator and improper power on/off of the module. The line ON# must be
connected only in open collector configuration.
In this document all the lines that are inverted, hence have active low signals are
labeled with a name that ends with a "#" or with a bar over the name.
NOTE
NOTE: When the power supply voltage is lower than 3.4V, to turn ON the module, the
NOTENOTE
pad ON# must be tied low for at least 3 seconds.

For example:
1- Let us assume you need to drive the ON# pad with a totem pole output of a +3/5 V
microcontroller (uP_OUT1):
2- Let us assume you need to drive the ON# pad directly with an ON/OFF button:
A flow chart with proper turn on procedure is detailed below:

5.2. Turning OFF the GE864-QUAD V2 / GE864-DUAL V2
Turning off of the device can be done in three ways:
• by software command (see GE864-QUAD V2 / GE864-DUAL V2 Software
User Guide)
• by tying low pin ON#
Either ways, the device issues a detach request to network informing that the device will not
be reachable any more. To turn OFF the GE864-QUAD V2 / GE864-DUAL via pin ON#, this
must be tied low for at least 1000ms and then released.The same circuitry and timing for the
power on shall be used.The device shuts down after the release of the ON# pin.
The following flow chart shows the proper turnoff procedure:
TIP:
TIP:
TIP:TIP:
To check if the device has powered off, the hardware line PWRMON must be
monitored. When PWRMON goes low, then the device has powered off.

5.2.1. Hardware Unconditional Restart
WARNING:
The hardware unconditional Restart must not be used during normal operation of the
device since it does not detach the device from the network. It shall be kept as an
emergency exit procedure to be done in the rare case that the device gets stacked
waiting for some network or SIM responses.
To unconditionally Restart the GE864-QUAD V2 / GE864-DUAL V2, the pad RESET#
must be tied low for at least 200 ms and then released.
The maximum current that can be drained from the RESET# pad is 0,15 mA.
A simple circuit to do it is:

NOTE:
NOTE:
NOTE:NOTE:
Do not use any pull up resistor on the RESET* line nor any totem pole digital output.
Using pull up resistor may cause latch up problems on the GE864-QUAD V2 / GE864DUAL V2 power regulator and improper functioning of the module. The line RESET*
must be connected only in open collector configuration.
TIP:
TIP:
TIP:TIP:
The unconditional hardware reboot must always be implemented on the boards and
the software must use it as an emergency exit procedure.
