GPRS-T1
SATEL
The GPRS-T1 converter should be installed indoors, in spaces with normal air humidity.
When selecting the installation place, take into consideration that thick walls, metal partitions,
etc. will reduce the radio signal range. Installation in close vicinity of electrical systems is not
recommended, as it may adversely affect the device performance.
The module power supply source should provide sufficient output current and be equipped
with a battery.
The following installation procedure is recommended:
1. Connect the antenna to the socket on electronics board. Be careful not to damage
the socket.
2. Connect the terminals of control panel telephone communicator with the TIP and RING
converter terminals.
3. Connect the power leads to the +12V and COM terminals.
4. Connect the computer to the converter RS-232 (TTL) port (see: section "Local
programming through RS-232 (TTL) port").
5. Turn on the converter power supply.
6. Using the GPRS-S
OFT
program, define PIN code for the SIM card (if the card requires
entering the PIN code) to be installed in the converter.
7. Turn off the converter power supply.
8. Insert the SIM card into the socket (see: Fig. 4).
9. Turn on the converter power supply. Logging the telephone into the GSM network may
take a few minutes.
Note: If the SIM card PIN code is inconsistent with that defined in converter settings, the
inconsistency will be indicated by the electronics board LEDs (see: Fig.3 Example F).
The second attempt of using the PIN code will be made after 30 seconds. After
the third attempt to use the invalid PIN code, the SIM card will be blocked. In order to
enter the PUK code and unblock the SIM card, remove it and insert into the mobile
phone.
