2.7 Reset signal
RESET signal is used to reset the HD Traffic Receiver Module. Whenever this signal is pulled
low, the module is reset. When the device is reset it stops any operation and after the release
of the reset it is unconditionally rebooted, without doing any detach operation from the network
where it is registered. This behavior is not like a proper shut down because any GSM device is
requested to issue a detach request on turn off. For this reason the Reset signal must not be
used to normally shutting down the device, but only as an emergency exit in the rare case the
device remains stuck waiting for some network response.
The RESET is internally controlled on start-up to achieve always a proper power-on reset
sequence, so there's no need to control this pin on start-up. It may only be used to reset a
device already on that is not responding to any command.
9 / 40
Reset Signal Operating levels:
Signal Min Max
RESET Input high 2.2 V* 3.3 V
RESET Input low 0 V 0.2 V
* This signal is internally pulled up so the pin can be left floating if not used
If unused, this signal may be left unconnected. If used, then it must always be connected
with an open collector transistor, to allow the internal circuitry the power on reset and under
voltage lockout functions.
2.8 2.75V_out power output
A regulated power supply output is provided in order to supply small devices from module. This
output is active when the module is ON and goes off when module is shut down. The operating
range characteristics of the supply are:

The Module is equipped with a 50 Ohm RF connector from Murata P/N MM9329-2700B.
Moreover, it has the antenna pads on the PCB to accept spring clips for antenna contact.
2.15 Power up / down scenarios
In general, be sure not to turn on the module while it is out of the operating range of voltage in
Chapter 2.2.
2.15.1 Turn on the module
The module can be activated via SYS_EN signal. When switch on the Module the SYS_EN signal
needs to be driven to high level for at least 150ms
2.15.3 Turn off the module
To switching the module off the following procedures may be used:
＊ Normal shutdown:
Page 13 of 40
Topic：

Software controlled by sending the AT command over the serial application interface.
＊ Automatic shutdown:

2.15.4 Turn off The module using AT command
The best and safest approach to powering down the module is to issue the AT command. This
procedure let the module log off from 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
OFF mode. In this mode, only the RTC stays active.
Command syntax: AT+CPWROFF
Command Possible responses
AT+CPWROFF
Note: switch off the module
Test command
AT+CPWROFF=?
After sending AT+CPWROFF do not enter any other AT command. There are two ways to verify
when the module turns off.
＊ Wait for the “OK”. It indicates that data have been stored in the non-volatile memory and
the module turn off in less than 1 second.
＊ Also, you can monitor the 2.75V_out pin. The low state of 2.75V_out definitely that the
module is switched off.
When the module is in POWER OFF mode the application interface is switched off and must not
be fed from any other source. Therefore, your application must be designed to avoid any current
flow into any digital pins of the application interface.
OK
Or
CME ERROR: <error>
OK
2.15.5 Inserted and removal action direction
These models are made very thin so that they may be smaller in size and light in weight than
before. Take care not to give then excessive force and insert by sliding when mating them
together or un-mating them. Otherwise, breakage may result. To prevent damage from incorrect
insertions please confirm the correct position before mating connection.
