POCKET GPRS WATER
Quick Guide ver. 1.0 03/2009
Thanks for purchasing a Digicom product.
Pocket GPRS Water is a monitoring and signalling terminal based on the
GSM technology. It is ideal in the remote control and remote reading of water
and liquid meters and it is able to send via SMS the information to a specific
service center.
It can read the pulse counter and detect the wire cut alarm on 4 meters; as well
as the antitamper alarm of the device itself.
If an alarm is detected, Pocket GPRS Water will send immediately a notification
SMS to the Control Center, otherwise, depending on the factory setting, it will
send the meters reading every 15 days. Pocket GPRS Water is equipped with
an output to control an electrovalve.

INSTALLATION
1. Connect the antenna by inserting the O-Ring washer in the seat around the SMA
connector and screw tight.
To guarantee the IP 67 protection degree of the case the washer must stick the
device and the antenna.
2. Open Pocket GPRS Water to insert the SIM card and the cabling of pulse count
and of electrovalve.
3. Open the SIM holder by pressing and pushing it vertically towards the connectors.Now insert the SIM
card being careful of the SIM corner, so that the golden contact are downwords. Close the drawer,
press and push it counterclockwise the opening side to block and fix the SIM.
4. In the lower part of the device printed circuit look for the 6 connectors to which the female clips with
3 contacts must be put on after the correct cabling of meters and electrovalve.
5. Define which and how many cable glands you must use in your installation, considering the number of meters and the position
of the connectors on the printed circuit. Then insert the closing caps into the cable glands that are not used. In order to
guarantee the IP 67 protection degree of the case, screw tight the cable glands and stick the washer to the closing cap.
6. Insert the free cabling of the pulses counter or of the electrovalve into the cable glands, and go on screwing tight the cable
gland so that the washer perfectly stick the cable. In order to guarantee the IP 67 case protection degree, a single cable must
be inserted in the cable gland, that can also contain 3 wires inside.
7. The wires of the pulses counter or of the electrovalve must be stripped for about 7 mm so you can
insert them correctly in the female clips with 3 contacts.
8. To connect the wire in the terminal board, you need a screwdriver 2,5 x 0,4 mm.
9. Insert the screwdriver and press it in the upper hole of the female clip with 3 contacts. Insert the stripped wire and remove the
screwdriver; be sure the wire is correctly fixed to the clip.
10.Once the cabling is over, insert the female clip in the connectors of the printed circuit and press it at the bottom being careful
of the insertion way. Check carefully that the wires respect the contacts shown on the printed circuit:
Meter 1 Meter 2 Meter 3
Tamper1: wire cut meter 1 Tamper2: wire cut meter 2 Tamper3: wire cut meter 3
Cont.1: pulses counter meter 1 Cont.2: pulses counter meter 2 Cont.3: pulses counter meter 3
GND: common signal GND: common signal GND: common signal
Meter 4 Digital Input 5 Electrovalve output
Tamper4: wire cut meter 4 +4V1: not used Open E.V.: opening signal
Cont.4: pulses counter meter 4 Level Sense: digital input Close E.V.: closing signal
GND: common signal GND: common signal +16V: common signal
11.Once the cabling and testing is over, you can turn on the device by connecting it to the battery. Look for the Power connector
on the printed circuit; it is placed between the connectors 3 and 4 and insert the battery cables being careful of the insertion
wa y.
12.When the battery is connected, the GSM and STATUS leds will be turned off and won’t give any indication.
13.Now press PUL1 – Start button, placed between the connectors 1 and 2, for 5 seconds, then release it and check that leds are
turned on. The GSM led, near the SIM holder, will blink quickly during the search for the GSM network. When the blinking
slows down, it means the registration to the GSM network has been successful.The STATUS led, placed near the battery can
blink slowly or quickly depending on the device configuration.
From now on the operating Center will be able to set the device via SMS. When finished, close the device.

BATTERY REMOVAL
A Li-Thionyl 3,6V – 14Ah removable battery is available inside the device. This supplies
the power to Pocket GPRS Water. To remove the battery it is necessary to open the case,
take out the battery connector, cut the two self-locking bands with a wire cutter and remove
the battery.
To insert a new battery you need two new self-locking bands 200 x 3,6 mm. Insert the
new band into the loops on the printed circuit, then place the battery considering the
wire lenght and the position of the power connector (power). Fix the battery by pulling the
bands. The new battery must be compliant with. To discharge the old battery, please refer
