1.4. Safety Precautions
The following safety precautions must be observed during all phases of the operation, usage,
service or repair of any cellular terminal or mobile incorporating HMS1. Manufacturers of the
cellular terminal are advised to convey the following safety information to users and
operating personnel and to incorporate these guidelines into all manuals supplied with the
product. Failure to comply with these precautions violates safety standards of design,
manufacture and intended use of the product. Siemens AG assumes no liability for
customer’s failure to comply with these precautions.
When in a hospital or other health care facility, observe the restrictions on the
use of mobiles. Switch the cellular terminal or mobile off, if instructed to do so
by the guidelines posted in sensitive areas. Medical equipment may be
sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment
and hearing aids can be affected by interference from cellular terminals or
mobiles placed close to the device. If in doubt about potential danger, contact
the physician or the manufacturer of the device to verify that the equipment is
properly shielded. Pacemaker patients are advised to keep their hand-held
mobile away from the pacemaker, while it is on.
Switch off the cellular terminal or mobile before boarding an aircraft. Make
sure it cannot be switched on inadvertently. The operation of wireless
appliances in an aircraft is forbidden to prevent interference with
communications systems. Failure to observe these instructions may lead to
the suspension or denial of cellular services to the offender, legal action, or
both.
Do not operate the cellular terminal or mobile in the presence of flammable
gases or fumes. Switch off the cellular terminal when you are near petrol
stations, fuel depots, chemical plants or where blasting operations are in
progress. Operation of any electrical equipment in potentially explosive
atmospheres can constitute a safety hazard.
Your cellular terminal or mobile receives and transmits radio frequency
energy while switched on. Remember that interference can occur if it is used
close to TV sets, radios, computers or inadequately shielded equipment.
Follow any special regulations and always switch off the cellular terminal or
mobile wherever forbidden, or when you suspect that it may cause
interference or danger.
Road safety comes first! Do not use a hand-held cellular terminal or mobile
when driving a vehicle, unless it is securely mounted in a holder for
speakerphone operation. Before making a call with a hand-held terminal or
mobile, park the vehicle.
Speakerphones must be installed by qualified personnel. Faulty installation or
operation can constitute a safety hazard.

SOS
IMPORTANT!
Cellular terminals or mobiles operate using radio signals and cellular
networks. Because of this, connection cannot be guaranteed at all times
under all conditions. Therefore, you should never rely solely upon any
wireless device for essential communications, for example emergency calls.
Remember, in order to make or receive calls, the cellular terminal or mobile
must be switched on and in a service area with adequate cellular signal
strength.
Some networks do not allow for emergency calls if certain network services or
phone features are in use (e.g. lock functions, fixed dialing etc.). You may
need to deactivate those features before you can make an emergency call.
Some networks require that a valid SIM card be properly inserted in the
cellular terminal or mobile.

3.2. Power Supply
HMS1 needs to be connected to a power supply at the B2B connector (5 pins each BATT+
and GND).
The power supply of HMS1 has to be a single voltage source at BATT+. It must be able to
provide the peak current during the GSM uplink transmission.
All the key functions for supplying power to the device are handled by the power
management section of the analog controller. This IC provides the following features:
• Stabilizes the supply voltages for the GSM / UMTS baseband using low drop linear
voltage regulators.
• Switches the module's power voltages for the power-up and -down procedures.
• Delivers, across the VEXT pin, a regulated voltage for an external application. This
voltage is not available in Power-down mode.
• SIM switch to provide SIM power supply.
3.2.1. Minimizing Power Losses
When designing the power supply for your application please pay specific attention to power
losses. Ensure that the input voltage VBATT+ never drops below 3.3V on the HMS1 board, not
even in a GSM transmit burst where current consumption can rise to typical peaks of 2A. It
should be noted that HMS1 switches off when exceeding these limits. Any voltage drops that
may occur in a transmit burst should not exceed 400mV.
In IDLE and SLEEP mode, the module switches off if the minimum battery voltage (Vbattmin)
is reached.
Example:
VImin = 3.3V
Dmax = 0.4V
Vbattmin = VImin + Dmax
Vbattmin = 3.3V + 0.4V = 3.7V
The best approach to reducing voltage drops is to use a board-to-board connection as
recommended, and a low impedance power source. The resistance of the power supply lines
on the host board and of a battery pack should also be considered.
Note: If the application design requires an adapter cable between both board-to-board
connectors, use a flex cable as short as possible in order to minimize power
losses.
HMS1 Hardware Interface Description
Confidential / Preliminary s
HMS1_HD_V01.62 Page 20 of 39 2006-08-21
Example: If the length of the flex cable reaches the maximum length of 100mm, this
connection may cause, for example, a resistance of 30mΩ in the BATT+ line and
30mΩ in the GND line. As a result, a 2A transmit burst would add up to a total
voltage drop of 120mV. Plus, if a battery pack is involved, further losses may
occur due to the resistance across the battery lines and the internal resistance of
the battery including its protection circuit.
Figure 3: Power supply limits during transmit burst
3.3. Power-Up / Power-Down Scenarios
In general, be sure not to turn on HMS1 while it is beyond the safety limits of voltage and
temperature. HMS1 would immediately switch off after having started and detected these
inappropriate conditions. In extreme cases this can cause permanent damage to the module.
3.3.1. Turn on HMS1
When the HMS1 module is in Power-down mode, it can be started to Normal mode or
Airplane mode by driving the IGT (ignition) line to ground. This must be accomplished with an
open drain/collector driver to avoid current flowing into this pin.
3.3.1.1. Reset or Turn off HMS1 in Case of Emergency
Caution: Use the EMERG_RST pin only when, due to serious problems, the software is not
responding for more than 5 seconds. Pulling the EMERG_RST pin causes the loss of all
information stored in the volatile memory. Therefore, this procedure is intended only for use
in case of emergency, e.g. if HMS1 does not respond, if reset or shutdown via AT command
fails.
The EMERG_RST signal is available on the application interface.
3.3.2. Turn off HMS1
HMS1 can be turned off by Normal shutdown: Software controlled by AT command.
Be sure not to disconnect the supply voltage VBATT+. Otherwise you run the risk of losing
data.

3.4. Power Saving
Intended for power saving, SLEEP mode reduces the functionality of the HMS1 to a
minimum and thus minimizes the current consumption.
The different sleep modes will be specified later.
3.5. RTC Backup
The internal Real Time Clock of HMS1 is supplied from a separate voltage regulator in the
analog controller which is also active when HMS1 is in POWER DOWN status.
In addition, you can use the VDDLP pin on the board-to-board connector to backup the RTC
from an external capacitor or a battery (rechargeable or non-chargeable). The capacitor or
battery is charged by the power management controller of HMS1. If the voltage supply at
BATT+ is disconnected, the RTC can be powered by the capacitor or battery. The size of the
capacitor determines the duration of buffering when no voltage is applied to HMS1, i.e. the
larger the capacitor the longer HMS1 will save the date and time.

The base band processor has an integrated SIM interface compatible with the 34.121 USIM
Testing IC Card standard. This is wired to an integrated SIM card holder. The USIM interface
supports 3V and 1.8V USIM cards.
Note: No guarantee can be given, nor any liability accepted, if loss of data is encountered
after removing the SIM card during operation.
Also, no guarantee can be given for properly initializing any SIM card that the user
inserts after having removed a SIM card during operation.
3.7. USB Interface
HMS1 supports a USB 1.1 Full Speed (12Mbit/s) device interface. The USB interface is the
recommended communication interface for high speed data transmission.
To properly connect the module’s USB interface to the host a USB 2.0 full speed compatible
connector is required. The HMS1 distribution contains the suitable USB driver to operate
HMS1 over USB. It is recommended to use this drive.
The USB host is responsible for supplying, across the VUSB_IN line, power to the module’s
USB interface, but not to other HMS1 interfaces. This is because HMS1 is designed as a
self-powered device compliant with the “Universal Serial Bus Specification Revision 1.1” (The
specification is ready for download on http://www.usb.org/developers/docs/).

3.8. Control Signals
Several control lines are signaling the states of the HMS1 module or control the module.
These states are power down, stand by, paging, GSM voice call, GSM data call, UMTS voice
call, UMTS data call or HSDPA connection.
3.8.1. PWR_IND Signal
PWR_IND notifies the on/off state of the module. High state of PWR_IND indicates that the
module is switched off. The state of PWR_IND immediately changes to low when IGT is
pulled low. For state detection an external pull-up resistor is required.
3.8.2. Status Signals
Two status signals (GREEN, BLUE) are provided for signaling the module’s connectivity
status:
• When searching for a network the signal 1 (GREEN) alternates at 2Hz
• When registered with a GSM network signal 1 is active
• When registered with a WCDMA network signal 2 (BLUE) goes active, signal 1 inactive

4. Antenna Interface
The RF interface has an impedance of 50Ω. HMS1 is capable of sustaining a total mismatch
at the antenna connector or pad without any damage, even when transmitting at maximum
RF power.
The external antenna must be matched properly to achieve best performance regarding
radiated power, DC-power consumption, modulation accuracy and harmonic suppression.
Antenna matching networks are not included on the HMS1 PCB and should be placed in the
host application.
The connection of the antenna or other equipment must be decoupled from DC voltage. This
is necessary because the antenna connector is DC coupled to ground via an inductor for
ESD protection.
4.1. Antenna Installation
To suit application requirements the HMS1 module adapts an internal antenna from Skycross
that is connected to the two antenna pads:
Figure 4: Internal antenna for HMS
4.1.1. Test Antenna
For production and type approval test the HMS1 module also provides a subminiature
coaxial switch from Hirose Ltd. The product name is:
MS-156NB

5.8. Electrostatic Discharge
The HSDPA engine is not protected against Electrostatic Discharge (ESD) in general.
Consequently, it is subject to ESD handling precautions that typically apply to ESD sensitive
components. Proper ESD handling and packaging procedures must be applied throughout
the processing, handling and operation of any application that incorporates a HMS1 module.
Special ESD protection provided on HMS1:
• Antenna interface: one discharge circuit
• SIM interface: serial resistor, clamp diodes for protection against over voltage.
• The remaining parts of HMS1 are not accessible to the user of the final product (since
they are installed within the device) and therefore, are only protected according to the
“Human Body Model” requirements.
HMS1 has been tested according to the EN 61000-4-2 standard. The measured values can
be gathered from the following table.
Table 14: Measured electrostatic values
Specification / Requirements Contact discharge Air discharge
CE ETS 300342-1 (June 1997)
ESD at SIM port ± 4kV ± 8kV
ESD at antenna port ± 4kV ± 8kV
ESD at 3.6V in, GND ± 4kV ± 8kV
Human Body Model (Test conditions: 1.5kΩ, 100pF)
ESD at SIM port ± 8kV ± 15kV
ESD at antenna port ± 8kV ± 15kV

Note: Please note that the values may vary with the individual application design. For
example, it matters whether or not the application platform is grounded over external
devices like a computer or other equipment, such as the Siemens reference
application described in Chapter 7.
