3MATERIAL NEEDED FOR THE INSTALLATION
3.1 CONTENTS OF THE XCOM-SMS COMMUNICATION SET
The communication set Xcom-SMS contains the following material:
3.2 ADDITIONAL ITEMS
In addition to the material delivered with the communication set the use of an Xcom-SMS
necessitates a micro SIM card as well as a mobile phone that can send and receive SMS
messages. During installation there is also need for a computer and a slot headed screwdriver.
4INSTALLATION
There are two phases in installing an Xcom-SMS:
1. Configuration of the Xcom-SMS, using the Xcom Configurator software supplied on
the micro SD card
2. Wiring of the module
4.1 CONFIGURATION OF THE XCOM-SMS
Your Xcom-SMS module needs to know the PIN code of your micro SIM card in order to send SMS
messages, just as a mobile phone. You also have to enter the phone number linked with this micro
SIM card. During this phase you may also enter a test mobile phone number to which test SMS
messages, operating reports of your system and alarms will be sent.
To store these data in the Xcom-SMS you will have to use the micro SD card supplied with the
device.
1 Quick guide
1 Xcom-SMS with antenna
1 communication cable, 2m
1 micro SD card with adapter (contains
product documentation in pdf-format as
well as the Xcom-SMS configuration
software.)
Mounting plate

Studer Innotec SA
Xcom-SMS
User manual V 1.0.0 11
1. PIN Code:
Here you should enter the PIN code supplied with your micro SD card. It's a code of 4 to 6
digits. This code is mandatory except if it has been removed, using a phone, or if the SIM
card comes without a PIN code.
2. SIM Card Phone Number:
Here you should enter the phone number assigned to your micro SIM card. We
recommend to enter the international phone number format indicating the country
code from where the system will be operating. In the example above the country code is
+41, which is the country code for Switzerland.
3. Owner Phone Number:
Here you should enter the phone number to which messages and reports from your
system will be sent as well as the automatic message that confirms that the configuration
has been successful. It is recommended to use an international format with the country
code of the country where the system will be operating.
4. User Key:
Here you should enter the access code that you would like to use when accessing the
system in the future. This code (<key>) will be necessary when sending messages to your
system. Find out more about its signification and format, in chapter 6.2. This code is
mandatory and you will need it in order to generate the configuration files. Remember to
write down this code, without it it's impossible to communicate with your Xcom-SMS.
5. When all requested fields are filled out, press "Generate" to create the configuration files.
5. A window will automatically confirm the successful file generation. Click on OK, the
configuration of your SD card is completed.
You may now remove the SD card from your computer and insert it into the Xcom-SMS.
4.2 WIRING AND AUTOMATIC POWER-UP
Wiring the system is easy but requires meticulous attention in order to facilitate the smooth
functioning of the system. Once connected to your system the power-up will be automatic.
The SD card delivered with the Xcom-SMS contains a software update for all the
devices of the system (Xtender/VarioTrack/VarioString/…). When the Xcom-SMS is
connected, it will verify the software version of each device connected to the
communication bus. If the software version on the SD card is more recent than the
existing version on the devices, they will be updated which will cause a restart (with
interruption of operation) in the corresponding devices.

1. Insert the micro SIM card. It is a push-push connector (push to insert and push to eject). Insert
the micro SIM card until you hear a "click" from the spring.
2. Insert the micro SD card that contains the configuration files of your Xcom-SMS (see chapter
4.1). It is a push-push connector (push to insert and push to eject). Insert the micro SD card
until you hear a "click" from the spring.
3. Adjust the antenna (rotate the antenna and manually tighten it).
4. Check the termination on the device to which you will connect the Xcom-SMS. If the system
contains several devices it is necessary to connect the Xcom-SMS to one of the ends of the
system. Connect your module with the supplied cable to a free communication connector
in the system.

Figure 4.2: Connection schematics for Xcom-SMS
(example 2: system with several devices)
The start-up is automatic once the Xcom-SMS is connected and powered by your system. The
Xcom-SMS will perform different sequences indicated by the bi-coloured LED (red/green) situated
next to the communication cable. These sequences are summarized below:
1. Start-up of the Xcom-SMS. The bi-coloured LED will blink orange (green and red at the same
time) 2x repeatedly.
2. If your system requires an update the communication module will perform it automatically
depending on the contents of the SD card. It can be the update of one configuration file or
a complete system update. It can be quick or long, depending on its contents and can take
from a few seconds to several minutes (update of the entire system). When an update starts
the bi-coloured LED lights up for 1.5 seconds in orange, then keeps blinking in red.
3. Once the update is completed the module will access the micro SIM card and the
configuration files on your SD card. This sequence is indicated by the LED blinking in orange 2x
repeatedly.
With one other device in the system the termination on the other device should be
put to T as in "Terminated". See figure 4.1.
An incorrect setting of the terminations can lead to an erratic running of the system
or impede its updating.
With more than two devices in the system all Studer devices should be put to O as
"Open" apart from the devices at the ends of the communication chain. These
devices should be put to T as "Terminated". The Xcom-SMS does not have a
termination since it has only one communication cable port. See figure 4.2
An incorrect setting of the link ends can lead to an erratic running of the system or
impede its updating.
By default, the termination is terminated (position T) on each of Studer Innotec SA's
products.

4a. If everything functions well and the GSM connection has been established with your mobile
phone operator the module will start blinking in green 2x repeatedly. It will send a confirmation
SMS of the start-up to the phone number entered in the Xcom Configurator in the field "Owner
Phone Number". If you would like to send another test-SMS manually, briefly push the button
of the Xcom-SMS.
4b. If the system has not been able to complete properly the start-up, it will blink red 2x repeatedly.
No SMS will be sent. If you have a remote control (RCC-02/-03) an error message will be
displayed indicating the problem (if the error has been identified). For instance, if there is no
micro SIM card inserted into the Xcom-SMS, the RCC will display:

SD card inserted (high priority)
When a SD card is inserted the red and green signalisation LEDs blinks
simultaneously (orange) during 1.5 seconds and indicates that the card is
read/inserted correctly.
Update of the Xcom-SMS
During update of the Xcom-SMS (as soon as a micro SD card containing an
update has been inserted) the signalisation LED blinks red.
The updating process may take between 3 and 15 minutes. During this
period it is possible that the signalisation LED will stop for an instant. The
updating process is finalised as soon as the red signalisation LED stops
blinking for at least 20 seconds. Never interrupt an updating process.
Error detected during the update process or during data logging
If the Xcom-SMS detects an error, the red signalisation LED is continuously lit.
Micro SD card is full
If the Xcom-SMS detects that the micro SD card is full, the red signalisation LED
will flash.
Fatal errors of the Xcom-SMS
These errors will prevent the communication between the system and your
phone. The red signalisation LED will blink 2x repeatedly if the Xcom-SMS is facing
one of the following errors:
The micro SD card is not configured
The SIM card is not inserted
The PIN code of the SIM card is wrong
The SIM card is locked. Use a mobile phone and the PUK code to unlock
the SIM card.
Impossible to connect to the phone network.
In either case you will have to solve the problem (see chapter "Troubleshooting")
and then disconnect and reconnect the Xcom-SMS to its Xtender system
(disconnect and then reconnect the cable).
Occasional errors of the Xcom-SMS
The red signalisation LED blinks 2x once. These occasional errors are not serious
and will not prevent the use of the Xcom-SMS. For instance, the Xcom-SMS has
not been able to send an SMS.
Start-up of the Xcom-SMS
The signalisation LED blinks 2x repeatedly in orange (green and red LED lit
simultaneously) during the start-up of the system. During this period the Xcom-
SMS is not yet in operation.
In operation (low priority)
The green signalisation LED blinks 2x repeatedly if the Xcom-SMS is in operation
and none of the above states are present.

6HOW TO USE THE COMMUNICATION MODULE
6.1 OVERVIEW
A large number of the system's functions are accessible using the Xcom-SMS. However, it is not
possible to access all functionalities of the system remotely or though SMS.
The Xcom-SMS module includes the following functionalities:
Operating reports by SMS
Events sent by SMS
Start / Stop a device
Control the auxiliary relays
Access to the parameters (Read / Write)
Reading the user information
Changing the access code
Subscribe / Unsubscribe to reports and system alarms
Changing the language
Help
6.2 SECURE ACCESS
The Xcom-SMS module protects your system with an access code in order to avoid that a third
party takes control over a system by knowing its phone number. This access code, indicated <key>
in this document, is a unique code of 6 characters. These characters can be composed of
numbers ('0' to '9'), upper case or lower case letters ('a' to 'z' et 'A' to 'Z'). The access code is case
sensitive.
As it is not possible to identify the sender of an SMS command, the access code has to be used in
the beginning of each SMS. The access code must be followed by a space in order to be
acknowledged.
By default the access code is set to: 123456
It is highly recommended to change the access code to guarantee the security of your system
(see the command "newkey").
If an SMS is sent using an incorrect access code <key>, the system will send an error message in
return if it's possible to identify the sender. The error message has this format:
Xcom-SMS Error: wrong key
Attention, in case of loss of the code the configuration has to be repeated from
scratch using the Xcom Configurator available on the micro SD card.
Your installer may also reset the access code if necessary.
The number of consecutive error messages has been limited to 5. Thereafter the
Xcom-SMS is blocked during 24h before taking in consideration any new SMS.
This function prevent the system from being hacked by the scanning method which
would create important SMS costs (in reply) by the Xcom-SMS.

Xcom-SMS
User manual V 1.0.0 19
6.3 ACKNOWLEDGEMENT OF RECEIPT
Each message received by the Xcom-SMS will generate a return message that acknowledges
whether the SMS has been processed. It is possible to deactivate the return message function with
the command "smsrsp", see chapter 0.
If an SMS is sent with incorrect formatting or in a format unknown to the Xcom-SMS, the system will
return an error message by SMS if it is possible to identify the sender. The error message has this
format:
Xcom-SMS Error : wrong sms format
6.4 SMS FORMAT
SMS messages sent to the Xcom-SMS must have the following format:
The SMS should always start with the system access code <key>. The access code is
followed by one or several commands.
The following characters are authorized in the SMS commands:
oLower case letters 'a' to 'z'
oUpper case letters 'A' to 'Z'
oNumbers '0' à '9'
oSpecial characters; namely:
'.'
','
'?'
'='
When the Xcom-SMS receives an SMS it starts by verifying the access code <key>. If the access
code is correct the commands contained in the SMS will be controlled and then executed.
