Pocket AL I/O
2.1.4. Connection of external antenna
Once the inputs installation is over you can go on with the connection of the
external antenna.
Be sure Pocket AL I/O is powerd off, then connect the antenna SMA male
connector to the connector of Pocket AL I/O screwing it clockwise. In case of
problems, do not force the connector but check the correct way.
Attention: for the best gain of the antenna, place it upward
and at least one meter over the floor. In case Pocket AL I/O
is installed inside cabinets with metal surfaces, we advice
to place the antenna outside the cabinet for the best GSM
signal.
Pocket AL I/O will operate only after the registration to the GSM network with
a good quality signal. Three ways to check the GSM signal:
• Through a mobile phone
Insert the SIM you will put in Pocket AL I/O in a mobile phone and verify which is the zone with the best signal.
• Through the Power and Status leds
Power on the modem and verify that Power and Status leds start blinking after a few seconds. The Power led blinking means
the modem is registered to the GSM network. The Status led blinking means there is a good GSM signal.
Attention: The sole signalling of registration to the GSM network through the POWER led does not guarantee
the presence of a sufficient signal to use the device.
• Through the #GSM# configuration command
Though this command you can verify precisely the best place to install the modem and the antenna. For further information
see the paragraph CONFIGURATION MESSAGES.
2.1.5. SIM insertion
Now you can insert the SIM card. Any PLUG-IN SIM is supported by Pocket AL I/O. In order to avoid damaging or losing information,
we suggest not to touch the SIM gold area.
Attention: USIM are not supported.
Attention: check with your telecom operator if the SIM is enabled for SMS traffic. We suggest to verify the
correct operation by using it with a standard mobile phone; it is important to disable the PIN code request
and to try sending/receiving SMS messages.
In case of problems:
- verify the residual amount (in case of prepaid SIM);
- verify and eventually insert the Service Center number (ask your telecom operator).
Probably the SIM card will be supplied in a card holder compliant with devices using
full-size SIM:
1. Remove the SIM carefully from the SIM holder.
2. Be sure Pocket AL I/O is off by disconnecting the power supply.
3. Insert the SIM in the specific slot (refer to the information on the device). Then to
extract the SIM, press on it and push it inside the device, then release it.
2.1.6. Power supply
Pocket AL I/O power supply is between 5 and 32 Vcc (Pwr of 6 PIN terminal board). With a 12Vcc power supply give at least
500mA.
The wires must be stripped for about 10 mm so you can insert them correctly in the female clips.
Attention: The voltage must not exceed the indicated maximum value as this may damage the product.
