INSYS GPRS 5.0 serial
HSComm
The configuration of the INSYSGPRS 5.0 serial takes place via AT commands which are
entered by a terminal program or a control program in the form of character sequences.
For a simple set-up, all basic functions of the INSYS GPRS 5.0 serial can be entered without knowing the individual commands and their parameters, using the configuration
software.
The software can be installed on the operating systems Microsoft Windows 2000 and
Microsoft Windows XP. A terminal window to enter commands directly is available.
In Chapters 6 - Connections - and 7 - Functions -, the HSComm or another terminal program can be used for the configuration. The HSComm has an integrated terminal program. The AT commands can be directly entered at the menu item “Terminal”.
The HSComm checks the connected device during startup. By default, only those settings
can be selected which are implemented in the identified device.
The buttons in the right column can be used to select the current settings, to restart (reset) the device, or to set the factory settings (default).
The selected configuration of the parameters is only sent to the INSYS
GPRS 5.0 serial after you click on the button Send values.
Menu File. The current configuration can be saved as a file and re-loaded at a later date.

INSYS GPRS 5.0 serial
Additional information for leased line
The INSYS GPRS 5.0 serial will automatically establish a leased line after the device is
switched on, or after a reset. The connection is monitored and re-established after interruptions.
For the implementation the selection of the remote terminal – CSD, IP or URL – is required as a first step. In our example, we selected an IP address as remote terminal.
In a second step, the IP address of the remote terminal must be stated together with the
according port. In our example, this is the IP 192.168.100.1 with port 80.

The connection setup and the connection itself are monitored.
If the connection can not be established (network failure,
no response from remote terminal) or if the connection is
terminated, the INSYS GPRS 5.0 serial will automatically
start reconnecting.
To limit the connection costs for inaccessible remote terminals (for each connection setup data packets are created and billed), the delay time will increase for every
new repeated attempt.

5.2.4 During the connection
5.2.4.1 Keep Alive
The data transfer via GPRS is packet-oriented. If no side of the
TCP connection sends data, there will be no traffic via the
transmission link. This also means that it can not be determined
if the remote terminal has disappeared without properly terminating the connection (e.g. due to a failure of the radio network
or a failure of the remote terminal).
It can also happen that GPRS network providers terminate connections themselves, if there is no data transfer for an extended
period of time, to be able to offer the resources to other participants.
For these cases, TCP offers a suitable accessory by sending Keep
Alive messages. The period between two monitoring packets can
be set to 1 minute steps (or be turned off completely). If three
successive monitoring packets are not responded to, the connection is regarded as terminated, and the INSYS GPRS 5.0 serial
returns to offline mode. If the device is configured as a leased
line device, the connection will then be re-established.
Keep Alive will mostly be used for leased lines, because the application on location is usually not able to assume the connection control and monitoring.
Alternatively, the settings can be entered or modified using the
terminal program.
Note: Keep Alive generates traffic; in principle, each Keep Alive
packet is an empty TCP/IP message which must be confirmed. For one Keep Alive two empty TCP/IP messages
with 40 bytes each are required.
When selecting the timeout, besides ensuring that the connection is monitored, the pricing of the current GPRS contract must
also be considered.

5.2.4.2 Forming data packets
For a TCP/IP-based transmission such as the “TCP transparent”
connection, the transmitted amount of data consists not only of
the sum of all user data of the application and the required TCP/IP
headers.
Each TCP/IP message has a protocol overhead of 40 bytes. For each
message there is also a confirmation message from the remote
terminal with 40 bytes as well.
It is important to select the suitable parameters for the application
to form the TCP packets in the integrated TCP/IP stack.
The INSYS GPRS 5.0 serial sends a data packet to the remote terminal when:
INSYS GPRS 5.0 serial
AT**TCPAGG=
<agg-time>
¾ The maximum size of 512 bytes is reached
¾ Since the preset waiting time (default: 100 ms) no character
has been sent via the serial interface, and data is already
waiting in the send buffer
AT**TCPAGG=100
For a calculation example see Chapter 8.8.3

5.2.5 Termination
Connections can be terminated as follows:
Manual termination using the ATH command in online command
mode
By DTR drop (for the setting AT&D2)
If the remote terminal hangs up
After switching from data mode to online mode, the connection
will remain established. However, data is no longer transmitted to
the remote terminal. The online command mode is also entered by
DTR drop (setting AT&D1) or by activating the reset input twice
within 10 seconds.

GSM Data Connection (CSD Call)
CSD is the simple modem-like data connection in the GSM network,
without using the GPRS service. Remote terminals for the connection can be analogue modems, ISDN adapter, or GSM devices.
With the help of HSComm, the INSYS GPRS 5.0 serial can automatically accept the CSD call. Click on the tab “Basic Settings”.
5.3.1 Connection setup
Dial the number to which a connection is to be set up (always with
dialing code, except for special provider numbers).

Connection
Direct GPRS Connection via PPP
When directly using the GPRS functionality of the GSM/GPRS engine, the INSYS GPRS 5.0 serial will only make PPP raw data available after the dial-up into the GPRS network has taken place. In this
case, the application must perform the required protocol stacks
(PPP, TCP/IP) for the application. In this mode, the TCP/IP stack of
the INSYS GPRS 5.0 serial is not active.
Example: Connection via the RDT network of a PC.
In this mode, the INSYS GPRS 5.0 serial is the PPP server.
5.4.1 PDP context
With the PDP context, the Access Point Name (APN) of the GPRS
network provider is specified.
Note: see also Chapter 10 "GPRS Dial-in Parameters"
E.g.: The Vodafone APN address is
WEB.VODAFONE.DE.
There is basically the possibility to define different PDP contexts; in
this case it is stored as context “1” (see also Chapt. 6.2.4 “AT commands for GPRS”).
Note: The PDP context can not be stored permanently; it must be
re-entered every time the device is restarted.
AT+CGDCONT=1,

restart and reset, without user intervention.
All four globally used frequency ranges 850 MHz, 900 MHz,
1800 MHz and 1900 MHz are supported. At the respective
location, the INSYS GPRS 5.0 serial will automatically operate
with the frequency range provided by the network provider.
Before using the INSYS GPRS 5.0 serial, you should
check the certification requirements in the country of
deployment.

6.3.2 Scheduled logout/login
For function support even after infrastructure changes and
network software updates by the network providers, the INSYS GPRS 5.0 serial can be logged out of the GSM network via
a timer. The timer can be set by the hour up to a maximum of
99 hours and starts when the device is switched on. One
minute after the logout, the INSYS GPRS 5.0 serial will automatically log back in. The timer restarts.
If a TCP transparent or a data connection (CSD or GPRS) is

6.4.5 SMS storage locations
The automatic processing of an incoming SMS takes place via an independent, module-internal interface and has usually no effect on the
communication between the application and the GSM/GPRS engine.
Only when the SMS memory is accessed (especially reading and deleting), it can happen that the µcontroller accesses the SMS storage
location at the same time. In this case, the application would receive
ERROR as response. The application should therefore execute the
command once more, if necessary.
The INSYS GPRS 5.0 serial evaluates all SMS storage locations made
available by the GSM/GPRS engine (storage locations of the SIM card
and storage locations in the engine itself).

Remote Configuration
During a CSD or “TCP transparent” data connection, the INSYS GPRS 5.0
serial can be switched to remote command mode by entering the escape
sequence via the data connection from the remote terminal.
<Pause>
****
<Pause>
Note: After the 4 escape characters were entered (1 second pause before and after the entry, no return - <CR> -) at the local device,
the remote configuration at the remote terminal is activated. The
data connection is maintained in the background. The 4 escape
characters must be entered within 1 second.
If this was configured, the configuration password is queried before the
switching to the remote command mode occurs.
Note: see also Chap. 6.1.1 – Password protection
After the escape sequence is detected, the prompt for entering the
password appears.
If no valid password is entered within 30 seconds (attention: complete

Firmware Update
The firmware of the µcontroller can be loaded locally (via the serial interface), and remote (CSD or "TCP transparent" connection).
Before the firmware is updated, hardware handshake must always
be activated (INSYS GPRS 5.0 serial and remote terminal).
The process is started. The device prepares itself for receiving the new
firmware.
After the response, the firmware (file with the ending *.hex) is sent as a
text file.
After the file has been received, the device needs up to 60 seconds to
complete the upload. After that, the INSYS GPRS 5.0 serial will automatically restart.
Note: Depending on the loaded firmware version, the settings for the
extended functions are reset to factory settings after the update.
The SIM card PIN (AT**PIN) and the standard command settings of
the GSM/GPRS engine are maintained, which means that if automatic call acceptance (e.g. ATS0=2) is activated, the device can still
be accessed from outside to enable the re-configuration of the extended functions per CSD call via remote configuration.

Each AT command starts with the letters AT and ends with a “Carriage Return” (CR).
Capital and small letters will both be accepted, but the leading characters must be either
‘AT’ or ‘at’. The command line is evaluated after the modem receives a Return command. In the description, a parameter with the letter “n” means that it can have various
values.
For example ATC<n>, where “n” can have the value 0 or 1, e.g. ATC1 (DCD always on).
For commands which expect a parameter but don't have a parameter, the modem will
automatically assume the parameter 0. For example, the commands AT&D and AT&D0
will have the same effect.
The commands are acknowledged with “OK” or “ERROR”. A command that is being edited will be interrupted by any further incoming character. Therefore, the next command
must wait for acknowledgement to avoid the deletion of the current command.
The standard AT commands can be entered locally via the serial interface if the device is
in offline state. In the online command mode, only the commands ATH and ATO are
available.
The extended INSYS AT** commands can be entered locally as well as remote (remote
configuration) and in most cases also via SMS. The configuration via SMS is restricted to
commands with responses of up to 140 characters.
Lining up several commands per input line is usually not possible. Further commands can be sent only after the processing of the previous command is completed with the output of the response.

8.1.2 GPRS
When using data services via GPRS, providers offer various contract options, especially
regarding the pricing (basic price, basic data volume, billing unit). Please contact your
provider for further information.
In general, GPRS providers bill every time a connection is terminated and daily at midnight (the provider will terminate the connection at this time), and all accumulated data
are rounded to the billing unit.
We therefore recommend selecting a rate which offers the smallest possible billing unit.
Many GSM/GPRS providers offer so-called M2M rates, which have an exact 1 kb billing
matrix.
58
Mai 06
INSYS GPRS 5.0 serial
Information Regarding GPRS
The transmitted amounts of data not only consist of the sum of the application user
data. They are rather packed into TCP/IP packets, which also generate network loads
and therefore add to the total costs.
It is also important to select parameters adjusted to the application to form TCP
packets:
¾ Maximum size (the packet is sent when this maximum size is reached)
¾ Maximum waiting time (the current packet is sent when the time has expired, see
AT**TCPAGG)
8.2
Network Design
The GPRS system is intended as additional service within the scope of the GSM system.
The GPRS data exchange (GPRS = General Packet Radio Services) runs packet-oriented,
based on the Internet Protocol (IP).
The following figure shows the basic design, where the application has to provide the
TCP/IP/PPP stacks. This is required when using the standard GPRS functionality of the i–

TCP Transparent
This function represents the main characteristic of the extended function. By means of
the integrated TCP/IP stacks, the INSYS GPRS 5.0 serial functions as “modem emulation”
for the application; the user data are provided transparently via the serial interface ("TCP
transparent" connection).
There is no need for the application to process any additional protocol stacks.
Due to the fact that the IP address of the the INSYS GPRS 5.0 serial can not be accessed;
only outgoing TCP/IP connections are supported.

8.4
Information Regarding GPRS
IP Addresses/Accessibility
The IP address of the GPRS end device is dynamically allocated by the provider and is
temporary, i.e. during the next dialup at the provider a new IP address is allocated.
In almost all GPRS networks the IP address can not be accessed from outside (routingenabled), as the providers perform the addressing for the switch from GPRS networks to
the “normal Internet” via a NAT table (Network Address Translation) to manage the address area limited by IPV4.
Furthermore, firewalls offer a security aspect, so the GPRS device is not accessible by socalled scanners because the IP address can not be accessed. As GPRS is billed by the
amount of data, this prevents unauthorized data traffic.
This also means that the following functions may not be possible:
¾ Pinging the GPRS device from outside
¾ Establishing TCP/IP connections to the GPRS device from outside
¾ Sending UDP/IP packets to the GPRS device from outside
All connections (channels) must be opened starting with the GPRS device. This means
that the GPRS device or the application behind it can only react as CLIENT.
Exceptions to this restriction will be provided by the according provider, if available.
Please also contact your provider to clarify if it is possible to use a VPN (Virtual Private
Network) for possibly required server functionality.

Data Rates
The INSYS GPRS 5.0 serial has the following characteristics:
¾ GPRS Multislot class 12
¾ GPRS End device class B
¾ Support of coding scheme 1 to 4
¾ PBCCH Support
GPRS has several classes (multislot classes) which are relevant for the transmission
speed. The classes provide the maximum transmission speed for uplink and downlink.
The table below shows the number of time slots for the classes, which can be used for
uplink, downlink, and for the device altogether.
GPRS devices support all variants up to their own multislots.

scheme (CS). This information is unfortunately not available for the user. The network

Data rates of PC data only (without GPRS control data)
Note: The above mentioned values represent the theoretically maximum possible values.
In practice, the following applies:
GPRS will not provide guaranteed data rates or bandwidths for the application. The values allocated by the network provider (using coding schemes and time slots) can change
dynamically during a connection and, among other things, depend on the current
amount of connections in the GSM cell.
In the device class B, the INSYS GPRS 5.0 serial supports the GSM services GPRS, CSD and
voice. However, only one service can be executed at a time.
8.6
Quality of Service (QoS)
The above mentioned characteristic data rates (in the form of values such as “data
amount per hour” and maximum data amount) and delay times are a part of the Quality
of Services, among others.
Theoretically, there is a possibility for requesting a certain QoS profile from the provider
during the connection setup via AT commands (AT+CGQREQ) or to define a minimum
profile (AT+CGQMIN) which must exceeded by the QoS offered by the provider, in order
to enable the device to establish the connection.
Experience has shown that these settings will not show any success regarding performance improvement, as the providers always supply "Best Effort” as QoS, i.e. the best values according to the current network load during the moment of the connection setup.
8.7
Delay Times
Usually, there will be marginally higher delays than with a "normal" connection via GSM.
The delays will mostly be below one second.
The average delay times are stated with 700 ms, for GSM values of 500 ms are assumed.
In rare cases, delays of several seconds are possible; the applications at the GPRS end devices should therefore be set to maximum delay times.

software
The system consists of a data logger with 8 digital inputs and 4 analogue inputs. The received data can be output in adjustable intervals at the RS232 interface.
The evaluation software at the control center computer will either communicate directly
with the data logger via the RS232 interface, or via leased line modems for remote applications.
To save investment and maintenance costs (rent ...) when using leased line modems, the
connection should be made via a transparent GPRS modem.
In this case, the INSYS GPRS 5.0 serial is used. It is also used for leased line operation, i.e.
after being switched on it will automatically attempt to establish a connection with the
remote terminal, the INSYS virtual COM port. As soon as the connection is established, all
user data from and to the data logger are transmitted via a transparent TCP/IP connection. No adjustment is required for the data logger and the control center computer.
8.8.1.2 Data logger user data
A data logger message has the following setup:

8.8.2.3 TCP Keep Alive
Some GPRS providers terminate the connections when they are inactive. Vodafone, for
example, terminates the connection after approximately 30 minutes without data transfers. For this reason, applications that exchange data in larger intervals should consider a
Keep Alive timer. The TCP stack generates an empty TCP message in adjustable intervals
which the TCP remote terminal responds to. This will satisfy the expectations of the provider regarding the amount of data. The INSYS GPRS 5.0 serial provides this function.
The application will not notice this action.

INSYS GPRS 5.0 serial
Information Regarding GPRS
8.8.3 Calculation example
We assume a GPRS rate for data with a 1kilobyte billing matrix, as offered by T-Mobile
and Vodafone as M2M rate.
Usually, GPRS network providers bill once daily, e.g. once a day the sum of all accumulated data since the last billing is rounded to the next billing unit (here: 1 kilobyte).
Example T-Mobile: Contract M2M Connect (Date: September 2005)
¾ Basic fee: 3.95 Euro / month
¾ Data extension M2M Data 1 for 1 Mb free volume: 2.95 Euro / month
¾ Data extension M2M Data 2 for 2 Mb free volume: 3.95 Euro / month
¾ Data extension M2M Data 5 for 5 Mb free volume: 4.95 Euro / month
¾ Data extension M2M Data 10 for 10 Mb free volume: 6.95 Euro / month
The following examples show merely the pure data transmission. When a TCP/IP connection is established via theINSYS GPRS 5.0 serial, data is generated (128 byte). The INSYS
GPRS 5.0 serial will not terminate a once established connection automatically, i.e. the
amount of date for the connection setup may be ignored.
However, the following may occur:
¾ The remote terminal can no longer be reached (power failure in the control center, system crash, new IP address for the control center, …)
¾ The GSM/GPRS network breaks down temporarily
¾ The GPRS modem has a power cut
In all cases, the INSYS GPRS 5.0 serial will automatically attempt a new connection setup
to guarantee the availability of the application (attempts in intervals of 20s, 80s, 320,
1280s, 1h, 1h, 1h …).
For the M2M rates, for each (failed) connection setup attempt 1kilobyte amount of data
may be assumed (at a 1 kilobyte matrix); it is therefore recommended to plan a reserve
of 30 to 50 kb up to the according upper limit of the rate.

All specified technical data was measured with a nominal input voltage, full load, and an
ambient temperature of 77.00 °F. The threshold value tolerances are subject to the typical fluctuations. A maximum of one value may be operated in the threshold value range.
The values were determined for a GSM receiving field strength of 16. For lower field
strengths on site the values will increase, especially for CSD or GPRS data transmissions.
The current consumption during data transmissions may also increase if the antenna is
not adjusted correctly.
This can occur for the following cases:
The antenna and/or the antenna cable are not adjusted to 50 Ω impedance.

SIM-Card
To operate, the INSYS GPRS 5.0 serial requires a 3V/1.8V SIM card from a GSM provider.
The SIM card is the identification towards the network provider.
The SIM card must be placed into the carrier with the contacts downward to ensure that
the contacts are on top of each other.
Change the SIM card only when the device is switched off.
12.7
Internal Design
For the INSYS GPRS 5.0 serial, a µcontroller is placed in series between the external serial
interface and the GSM/GPRS engine.
All commands sent to the INSYS GPRS 5.0 serial via the serial interface are first received
and evaluated by the µcontroller.
Mai 06
77
Technical Data
INSYS GPRS 5.0 serial
If the command results in just one action by the µcontroller, the response to the application (e.g. OK) is created directly by the µcontroller.
If the GSM/GPRS engine is activated while commands are entered, the response to the
application is determined by the engine; in this case, the µcontroller will just relay them.
During CSD calls or standard GPRS connections the µcontroller relays the data transparently in both directions.
When using the integrated TCP/IP stacks (TCP transparent) of the µcontroller, the data
from the µcontroller is packed into the according protocol elements, sent via the
GSM/GPRS engine and vice versa.
The periodically performed status queries (AT**GSMREQ) and evaluations of incoming
SMS occur internally on another interface; they will generally not have an effect on the
communication between the application and the INSYS GPRS 5.0 serial.

14.1
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 TC63. 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.
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
80
Mai 06
INSYS GPRS 5.0 serial
Internationale Sicherheitshinweise
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.
14.2
Compliance with FCC Rules and Regulations
The FCC Equipment Authorization Certification for the TC63 reference application is
listed under the
FCC identifier QIPTC63
IC: 267W-TC63
granted to Siemens AG.
The TC63 reference application registered under the above identifier is certified to be in
accordance with the following Rules and Regulations of the Federal Communications
Commission (FCC).
Power listed is ERP for Part 22 and EIRP for Part 24
“This device contains GSM and GPRS Class12 functions in the 900 and 1800MHz
Band which are not operational in U.S. Territories.
This device is to be used only for mobile and fixed applications. The antenna(s)
used for this transmitter must be installed to provide a separation distance of at
least 20cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Users and installers must be provided
with antenna installation instructions and transmitter operating conditions for
satisfying RF exposure compliance. Antennas used for this OEM module must not
exceed 8.4dBi gain (GSM 1900) and 2.9dBi (GSM 850) for mobile and fixed operating configurations. This device is approved as a module to be installed in other devices.”
Manufacturers of mobile or fixed devices incorporating TC63 modules are advised to include instructions according to above mentioned RF exposure statements in their end
product user manual.
Please note that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
If the final product is not approved for use in U.S. territories the application manufacturer shall take care that the 850 MHz and 1900 MHz frequency bands be deactivated
and that band settings be inaccessible to end users. If these demands are not met (e.g. if
the AT interface is accessible to end users), it is the responsibility of the application
manufacturer to always ensure that the application be FCC approved regardless of the
country it is marketed in. The frequency bands can be set using the command
AT^SCFG="Radio/Band"[,<rbp>][, <rba>].
The FCC label of the module must be visible from the outside. If not, the host device is
required to bear a second label stating, “Contains FCC ID QIPTC63”.
