11  Internet remote access 

The web site 

www.GSMLink.cz

 enables GSM pager remote control (to 

users) and setting (to installers). The following features are enabled:  

 

To get internet access to an installed and powered GSM pager you will 

first be asked to register your GSM pager on the first page. You will find a 
unique registration code for your GSM pager on the warranty card.  

11.1 Reset GSM 

If you need to disconnect and then reconnect the GSM module to the GSM 
network, then use the command “MASTER RESET GSM”. 
This does not affect any settings and is typically used for GPRS activation or 
charging up credit. This command always requires the Master code. 

 

12  Central monitoring station communication  

The GSM pager allows central monitoring via GPRS data protocol. The 
central monitoring station (CMS) gets arming, disarming and alarm 
information. It also regularly checks the communication link to the car after it is 
armed.  So if anyone tries to tamper with GSM pager communications, it will 
indicate an alarm at the CMS. 
 

 

13  Additional features 

13.1  Car battery low voltage reporting 

The GSM pager checks the voltage of the car battery. If the voltage is too 

low (10V) it will notify users via an SMS message. This avoids complete 
discharging of the car battery if you forget to turn off your lights etc. 

13.2  Back-up battery  

The GSM pager can be backed up by a BB-01 battery. Thus, the GSM 

pager can keep sending information. Back up time is provided for several 
hours. The manufacturer recommends regular BB-01 checking once a year. 
The battery should be replaced every two years. Low voltage of the back up 
battery (below 4V) is reported to the user via SMS (change the battery in this 
case). 

13.3 Car location 

If your GSM provider offers a location service, you have to activate the 

LOCATOR command after installation by the following SMS sequence:  

MASTER LOCATOR xx…x 

where:  

MASTER

           is the installers code 

 

xx...x 

 

is the provider’s sequence to obtain the position 
of the GSM pager SIM card  (check with your 
GSM provider for details)

  

 

After this sequence has been sent successfully once, the GSM pager 

memorizes the parameters and from this moment on you can obtain the 
location of the car by just sending the instruction  LOCATOR. 

 

Note: GSM location service may not be available in some countries. 

13.4  Pre-paid SIM card balance 

It is recommended not to use prepaid cards in the GSM pager. If you 
have no other choice than prepaid cards, you can enable the CREDIT 
instruction by following sequence:  

 

MASTER CREDIT  uuu..u  xx  yyy  zz  

 

where:  

uuu…u  

is the provider’s code to obtain the balance                                                                                                                                                                 

 

xx  

 

is the time period (in days) for regular checking 

 

yyy     

is the threshold level below which the balance is 
reported to the user (TEL1)

 

zz  

 

is the position of the first digit of the balance in the reply 
SMS from the provider

  

 

 

After this sequence has been sent once, the GSM pager will check 
the balance automatically every xx days and if the balance is lower 
than yyy the user will be notified (TEL1) 

 

If the CREDIT instruction is enabled in the above way, the  user can 
also obtain the current balance by the instruction CREDIT 

 

To disable the automatic balance checking set the time period “xx” 
to 00. 

13.5 Roaming 

If you travel abroad and your SIM card supports roaming, the GSM pager 
will work there too.

 

13.6 Siren activation 

If you are searching for a stolen car, you can operate the siren 

remotely by the following SMS instructions: 

 

MASTER SIREN   

turns the siren on for 10 minutes

   

MASTER SIREN ON

  

siren on permanently 

MASTER SIREN OFF

  

siren off 

 To avoid misuse of this option, only an installer can switch the siren on.

1 Before installation

 

The CA-1202 should only be installed by a professional installer. The 

manufacturer assumes no liability for damages caused by incorrect 
installation or use of this product.  

The Athos GSM pager is suitable for cars with 12 V and negative 

grounding. The main unit is designed for installation in the passenger 
cabin.  

Disconnect the car battery

 before starting installation; 

study the car 

owner manual first. 

Avoid drilling into the metal parts of the car body.  

Note:

 Use only proper crimping tools and parts to make connections. Cut 

all unused wires and insulate them properly.  

The thin wire which leads directly out of the central unit is the remote 

control and wireless detector antenna. The location of this wire affects the 
communication range. Place the antenna on a suitable plastic surface so 
that the other wires do not screen it. 

 

2 Wiring

 

 

YELLOW

 – siren output (+12V / max. 1,3A). 

 

 

Gray – instant activation input 

reacts to connection or disconnection 

from the ground (automatically recognizes logic).

 

 

WHITE – INP1 input

 - reacts to connection or disconnection from the 

ground (automatically recognizes logic). Reaction delay is 3 seconds

  

 

BLUE –

ignition key

 input (+12V). Be sure, that there is +12V while the 

key is on and while starting.

 

 

GREEN

 

– LED indicator

 – install it in a visible spot on the dashboard.  

Connect the other end of this lead to the GND.

 

 

BLACK – GND 

– connect to the original grounding in the car.

 

 

RED – power 12V - 

connect directly to the battery. Check that 

the installation is properly finished and that the GSM antenna is 
connected before powering up!!

 

 

ORANGE – back-up battery 

– connect a BB-01 optional battery 

(Jablotron) if desired. If the BB-01 is not connected, then ground the wire.

 

 

2x BROWN 

– immobilization circuit (8A permanently, max. 12A / 

3minutes). 

 

Pink 

– not used 

 

3  SIM card insertion 

1. 

Make sure, that the 

PIN password on the SIM is disabled

.  You can 

do this using a mobile phone (e.g. for NOKIA: MENU, SETTINGS, 
SECURITY SETTINGS, PIN CODE REQUEST, OFF). If your SIM card 
does not allow switching the PIN off, change the PIN to 0000. 

 

2. Activate the SIM card

 if necessary (see provider’s instructions), 

ensure that it works

 (by a mobile phone) and 

record its phone number

 

3. 

Using a thin pointed tool, press the colored button to release the SIM 

cardholder.  

Insert the SIM card into the holder

 with the gold contacts 

facing up and then reinsert the holder.

 

 

4  GSM antenna installation 

DO NOT switch the power on before the GSM antenna is connected

The provided antenna is adhesive and should be attached to the car window. 
The antenna should not be obstructed by any metal parts. It is recommend to 
install the antenna in a place where it is not easily visible (a tinted part of the 
window, behind the mirror etc.). If the car has an original GSM antenna 
installed, it can be used (if the connector is different, use an appropriate 
adapter). 

 

5 Initial powering-up of the GSM pager 

Make sure, that the GSM antenna is connected, the SIM card inserted 
and the wire harness installed properly. Then connect the power (car 
battery). The LED indicator will turn on and the siren will make a short 
chirp. Wait until the LED turns off (up to 1 minute).  

  If the LED starts to flash, no GSM network was found. In such a case 
turn the power off, remove the SIM card and try to use it in a mobile 
phone (at the place where the GSM antenna is).  Check also if the PIN 
protection is OFF (or set to 0000). If the SIM card logs into a network 
successfully, reinsert it in to the pager and repeat powering-up

.

 

After the GSM pager is powered up, you have to: 

a) 

Select  Mode 3

  by the command 

RESET EN 3

  

b) 

Enroll  remote controls 

(if used)  

c) 

Set the programmable features

 (phone numbers, DIP, SET, 

etc.). 

These can be done by:  

 

SMS instructions

 – see table 6.1. 

For example sending an SMS: 

MASTER RESET EN 1

 to the GSM pager will select Mode 1. 

 

Internet page:  

www.GSMlink.cz

 

is the most convenient way. To 

register there you need to know the registration code (printed on 
the warranty card) and the master code (factory default is 
MASTER). 

 

SIM Card phone directory editing 

(see table 6.1 for list of features 

which can be programmed this way). After the initial powering-up a 
list of parameters is created in the SIM card phone directory. If you 
then insert the SIM card in to a mobile phone, you can set 
particular features (by entering numbers into the created list). The 
entry for Mode setting is not automatically created, but it is possible 
to make a new entry with the name: RESET EN and the number: 1. 
Data entered this way are read by the GSM pager after the SIM 
card is reinserted. For security reasons it is erased after reading. 

 

6  Enrollment of remote controls 

Up to 4 RC-4x remote controllers and can be enrolled to the GSM pager 

(after Mode 3 is selected by the RESET EN 3 instruction).  

Remote control enrollment: 

1. Switch the 

ignition on

  

2.  Send the SMS instruction:  

MASTER LEARN RC

 

 

If the siren is connected to the GSM pager it will chirp 3x and the 
LED will start flashing.  

3. Press and 

hold buttons 

 and 

 together for 3 sec on the remote 

control.  

 

A siren chirp confirms the enrollment.  

 

By enrolling the first remote control all other remote controls 
previously enrolled will be erased (all the remote controls you 
want to use must be enrolled during the same enrollment 
session). 

4. 

Exit 

enrollment by 

turning the ignition off
