GSM 622 modem is suitable for “TELECOSTER” telemanagement systems, installed in a remote position (e.g.
central heating site) for data communication to and from the central sites.
2. FUNCTIONS
GSM 622 modem is an E-GSM dual-band modem (900/1800 MHz) with a transmission speed configurable from
2400 to 14400 bps in non-transparent mode (with error correction).
It cannot communicate with modems having a transmission speed below 2400 bps (e.g. MCT 710).
It supports AT+ controls in conformity with standard ETSI GSM 07.05 & 07.07 & V.25ter.

9. SITING
The modem must be installed in a dry location that respects the relevant ambiental conditions given under 5.TECH-
NICAL DATA. If sited in a location classified as “Hazardous” it must be installed in a cabinet for electrical equipment
constructed according to the regulations in force for the class of danger concerned.
The modem can be mounted on a DIN rail and housed in a standard DIN enclosure.
The antenna must be installed in a zone covered by the chosen telephone operator, using, if necessary, the APA
812 extension.
10. ELECTRICAL CONNECTIONS
Proceed as follows :
• Loosen the four screws (6.3) that fix the cover to the base and separate the two parts.
• Mount the base on the DIN rail and check that the securing elements (6.4) anchor it securely
• Make the electrical connections according to the diagram and in observance of the safety regulations in force using
the following cables: :
– 1.5 mm2 for the power supply and the relay control outputs.
– 1 mm2 for C-Bus and RS232 for lenght limits see data sheet T 021.
• Switch on power (230 V~) and check its presence at terminals L – N and L1-N1.
• Switch off power, replace cover on base/terminal block and secure it with the four screws supplied (6.3).
• Connect the antenna cable (6.8) to the coupling (6.6) using the female-female connector (6.7)
You are advised not to insert more than two cables in a single terminal and if necessary to use an external junction
box .
11. C-BUS LINE CHARACTERISTICS
The C-Bus line’s communication speed can be set at 1200, 2400, 4800 and 9600 baud.
To set the desired speed, the TCB 908 tester can be used, connected to a PC.
The desired speed can be selected via the SWC 701 Remote Management software.
The C-Bus line can be up to 2000 metres long, with 100 slave units at the most, regardless of transmission
speed.
12. SIM CARDS
12.1 Purchase of SIM CARD.
You are advised to purchase the SIM card from your chosen GSM network service provider for business networks.
When purchasing, it is essential to request a card enabled for the transmission and reception of DATA with the
following communication modes: AUTOBAUDING; ASYNCHRONOUS; NOT TRANSPARENT (correction data
enabled).
12.2 Inserting SIM card in GSM 622
Before inserting the SIM card in the modem it is essential
to disable the PIN code of the card.
To do this, use a GSM cellular telephone and insert the SIM
card in it; then, following the instructions received from this
telephone, disable the PIN code.
To install the SIM card in GSM 622 proceed as follows:
– Ensure that the modem is switched off; You must NOT
insert or remove the SIM card while the modem is
switched on.
– Using a pointed object, press button (1) to extract card
holder (2).
– Insert SIM card (3) in the holder making sure that it is the
right way round
– Push in the card holder until it clicks into place.
– Power the modem.
12.3 GSM network signal strength indicator
LED (7.2) indicates the status of the modem :
- off : modem not ready;
- on : searching for signal, SIM card not inserted, absence of antenna or in reset stage
- slow flashing : signal present;
- rapid flashing : modem transmitting;
To know exactly the signal quality you must:
– connect GSM 622 to a computer (with SIM inserted and powered) and
– using a communication program or SWC 701 telemanagement program, send instruction “AT + CSQ” to the mo-
dem;
– read the reply coming from GSM 622:
– from 0 to 9 = the field is almost always too weak
– from 10 to 15 = the field is ususlly strong enough
– over 15 = the field is good
