1 Security
IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF
YOUR GSM-MODEM, READ THIS INFORMATION BEFORE USE!
Your cellular engine FALCOM C2D-SI is one of the most exciting and
innovative electronic products ever developed. With it you can stay in
contact with your office, your home, emergency services and others,
wherever service is provided.
This chapter contains important information for the safe and reliable use of
the FALCOM C2D-SI. Please read this chapter carefully before starting to
use the cellular engine FALCOM C2D-SI.
1.1 General information
Your FALCOM C2D-SI modem utilises the GSM/GPRS standard for
cellular technology. GSM is a newer radio frequency („RF“) technology
than the current FM technology that has been used for radio
communications for decades. The GSM standard has been established for
use in the European community and elsewhere. Your modem is actually a
low power radio transmitter and receiver. It sends out and receives radio
frequency energy. When you use your modem, the cellular system handling
your calls controls both the radio frequency and the power level of your
cellular modem.
1.2 Exposure to RF energy
There has been some public concern about possible health effects of using
GSM modem. Although research on health effects from RF energy has
focused for many years on the current RF technology, scientists have begun
research regarding newer radio technologies, such as GSM. After existing
research had been reviewed, and after compliance to all applicable safety
standards had been tested, it has been concluded that the product is fit for
use.
If you are concerned about exposure to RF energy there are things you can
do to minimise exposure. Obviously, limiting the duration of your calls will
reduce your exposure to RF energy. In addition, you can reduce RF
exposure by operating your cellular modem efficiently by following the
guidelines below.
1.3 Efficient modem operation
In order to operate your modem at the lowest power level, consistent with
satisfactory call quality please take note of the following hints.
If your modem has an extendible antenna, extend it fully. Some models
allow you to place a call with the antenna retracted. However your
modem operates more efficiently with the antenna fully extended.
Do not hold the antenna when the modem is „IN USE“. Holding the
antenna affects call quality and may cause the modem to operate at a
higher power level than needed.

FALCOM C2D-SI VERSION 1.07
1.4 Antenna care and replacement
Do not use the modem with a damaged antenna. If a damaged antenna
comes into contact with the skin, a minor burn may result. Replace a
damaged antenna immediately. Consult your manual to see if you may
change the antenna yourself. If so, use only a manufacturer-approved
antenna. Otherwise, have your antenna repaired by a qualified technician.
Use only the supplied or approved antenna. Unauthorised antennas,
modifications or attachments could damage the modem and may contravene
local RF emission regulations or invalidate type approval.
1.5 Driving
Check the laws and regulations on the use of cellular devices in the area
where you drive. Always obey them. Also, when using your modem while
driving, please pay full attention to driving, pull off the road and park before
making or answering a call if driving conditions so require. When
applications are prepared for mobile use they should fulfil road-safety
instructions of the current law!
1.6 Electronic devices
Most electronic equipment, for example in hospitals and motor vehicles is
shielded from RF energy. However RF energy may affect some
malfunctioning or improperly shielded electronic equipment.
1.7 Vehicle electronic equipment
Check your vehicle manufacturer’s representative to determine if any on
board electronic equipment is adequately shielded from RF energy.
1.8 Medical electronic equipment
Consult the manufacturer of any personal medical devices (such as
pacemakers, hearing aids, etc.) to determine if they are adequately shielded
from external RF energy.
Turn your FALCOM C2D-SI modem OFF in health care facilities when any
regulations posted in the area instruct you to do so. Hospitals or health care
facilities may be using RF monitoring equipment.
1.9 Aircraft
Turn your FALCOM C2D-SI OFF before boarding any aircraft.
Use it on the ground only with crew permission.
Do not use it in the air.
To prevent possible interference with aircraft systems, Federal Aviation
Administration (FAA) regulations require you to have permission from a
crew member to use your modem while the plane is on the ground. To
prevent interference with cellular systems, local RF regulations prohibit
using your modem whilst airborne.

FALCOM C2D-SI VERSION 1.07
1.10 Children
Do not allow children to play with your FALCOM C2D-SI modem. It is not
a toy. Children could hurt themselves or others (by poking themselves or
others in the eye with the antenna, for example). Children could damage the
modem or make calls that increase your modem bills.
1.11 Blasting areas
To avoid interfering with blasting operations, turn your unit OFF when in a
“blasting area” or in areas posted: „turn off two-way radio“. Construction
crew often use remote control RF devices to set off explosives.
1.12 Potentially explosive atmospheres
Turn your modem FALCOM C2D-SI OFF when in any area with a
potentially explosive atmosphere. It is rare, but your modem or its
accessories could generate sparks. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always,
clearly marked. They include fuelling areas such as petrol stations; below
decks on boats; fuel or chemical transfer or storage facilities; and areas
where the air contains chemicals or particles, such as grain, dust or metal
powders.
Do not transport or store flammable gas, liquid or explosives, in the
compartment of your vehicle which contains your modem or accessories.
Before using your modem in a vehicle powered by liquefied petroleum gas
(such as propane or butane) ensure that the vehicle complies with the
relevant fire and safety regulations of the country in which the vehicle is to
be used.
1.13 Non-ionising radiation
As with other mobile radio transmitting equipment users are advised that for
satisfactory operation and for the safety of personnel, it is recommended
that no part of the human body be allowed to come too close to the antenna
during operation of the equipment.
The radio equipment shall be connected to the antenna via a non-radiating
50 Ohm coaxial cable.
The antenna shall be mounted in such a position that no part of the human
body will normally rest close to any part of the antenna. It is also
recommended to use the equipment not close to medical devices as for
example hearing aids and pacemakers.

3.1.1 Determining the External Equipment Type
Before you connect the C2D-SI module (DCE unit) to external equipment,
you need to determine if the external hardware serial ports are configured as
DTE or DCE.
The terms DTE (Data Terminal Equipment) and DCE (Data
Communications Equipment) are typically used to describe serial ports on
devices. Computers (PCs) generally use DTE connectors and
communication devices such as modems and DSU/CSU devices generally
use DCE connectors. As a general rule, DTE ports connect to DCE ports via
straight through pinned cables. In other words, a DTE port never connects
directly to another DTE port. Similarly, a DCE port never connects directly
to another DCE port. The signalling definitions were written from the
perspective of the DTE device; therefore, a Receive Data signal becomes an
input to DTE but an output from DCE.
The C2D-SI is designed for use as a DCE unit. Based on the aforementioned
conventions for DCE-DTE connections it communicates with the customer
application (DTE) using the following signals:

4.2 Special functionality pins
Table 7 and table 8 show the pin-configuration of the AMP 177984-2.
In these tables CMOS means 2.8 V. You may use a 3 V or 3.3 V CMOS
level logic (never 5 V) on the 2.8 V I/O’s. However, it is required to add
serial resistance on all the lines you will use (typical value: from 4.7 to 10
KΩ).
There are a few pins needed for the operation of the module. The handling
of pins is described as follows.
Pin 30 (EN)
This signal is an input of the internal voltage regulator.
Pull to LOW to switch the voltage regulator off (for minimum current
consumption).
Pull to HIGH or leave the signal open if EN is not used.
Pin 27 (GPIO 1 Æ Flash_LED)
This signal can be used to show the current status of the module:
If GPIO 1 is LOW then the module is off.
If it is continuously HIGH then module is on, but not registered into a
network.
If GPIO 1 is flashing in a 2sec period then the module is on and
registered into a network.
If it flashes in a 1sec period then the module is on and a call is in
progress (incoming or outgoing).
GPIO 1 can be an input into a controller (here it needs to be driven by
an open collector circuit) or used together with a LED (see figure 3).

FALCOM C2D-SI VERSION 1.07
Figure 3: PIN 27
Pin 35 (SIMPREK)
This signal needs to be driven by an open collector circuit. It is used by the
module firmware to detect a SIM card exchange when the module is online.
A high to low transition means SIM card is inserted and the module will be
able to accept the AT+CPIN command. A low to high transition means SIM
card has been removed, the module will de-register from the network an
show the unsolicited error code CME ERROR: 10.
Figure 4: Sample application for SIMPREK
Pin 16 (RESET GSM)
This signal needs to be driven by an external open collector circuit.
• To issue a hardware reset pull the signal to LOW for a minimum of
100ms.

Pin 11 (SOFT_ON)
This signal needs to be driven by an external open collector circuit.
For switching the module on (external power must be connected!) set
the SOFT_ON signal to HIGH for approx. 3sec. The signal can be left
HIGH until module shall be switched off.
For switching the module off the commands AT+CPOF or
AT+CFUN=0 have to be issued.
- If SOFT_ON is HIGH then only the RF part of the module is off,
but the AT command set is still working (AT+CFUN=1 can be
used to wake up the RF part again) the Flash_LED stays HIGH.
- If SOFT_ON is LOW then the complete GSM engine goes OFF the
Flash-LED goes LOW. Some small power consumption will be
still there, use the EN pin to avoid that.
It is not recommended to switch the module on and off by means of the
power supply (e. g. by tying the SOFT_ON constantly to HIGH). The
module will so have no possibility to de-register correctly from the network
and this will cause problems at the next attempt to register.
Pin 18 (VCCRTC)
This pin is used as a back-up power supply for the internal Real Time Clock
of GSM/GPRS engine. The RTC is supported by the C2D-SI module when
powered on but a back-up power supply is needed to save date and time
when the module is switched off (see AT+CCLK to set the date and time).
If the RTC is not used, this pin can be left open.

4.2.2 Resetting the GSM module by AT+CFUN=1,1
If the GSM software is still running, while the user feels the need to reset
the module, AT+CFUN=1,1 can be used. This will de-register the modem
from the network and bring it into the state before the PIN could be entered.
The Flash_LED pin shortly toggle to OFF and back to ON again to show the
progress.

5.1 Receiver architecture
The GPS receiver in the FALCOM C2D-SI from FALCOM is a new GPS
receiver product that features the SiRFstarII chipset. This complete 12
channel, WAAS-enabled GPS receiver provides a vastly superior position
accuracy performance in a much smaller package. The SiRFstarII
architecture builds on the high-performance SiRFstarI core, adding an
acquisition accelerator, differential GPS processor, multipath mitigation
hardware and satellite-tracking engine. The receiver delivers major
advancements in GPS performance, accuracy, integration, computing power
and flexibility.

Figure 6: Default settings for the trickle power mode of FALCOM C2D-SI
trickle power mode: The FALCOM C2D-SI enters the trickle
power mode according to figure 6 (800 ms
OFF Time and 200 ms ON Time
) as soon as
valid GPS data are available. As a result the
average power consumption is reduced by
approximately 80 % (approximately 150
mW). The settings for the trickle power
mode can be modified using the SiRFstar
demo software. For example if the FALCOM
C2D-SI is configured to enter the OnTime
mode each 10s for a duration of 200ms the
average power consumption can be reduced
by approximately 95% (approximately
15mW, ca. 4,8mA at Vcc=3.3V).
Hint: The power-on scenario in Trickle
Power Mode differs from one in continuous

mode. If the module fails to acquire satellites
within a given period of time (approx. 150
sec), the module goes into an extended sleep
phase. The duration of this sleep phase is
approx. 30 sec. After that, the module wakes
up, make a reset and tries to acquire
satellites. This procedure repeats itself until
the GPS receiver can detect satellites.
