7.3.1 Procedure

Brief summary of the procedure for activating the GSM modem:

 Verify that the GSM subscription is activated for data traffic, and that the SIM card doesn’t

have the PIN code activated, by installing the SIM card in a cell phone and turning on the

phone. If the PIN code is activated it must be disabled. Then call the cell phone from

another phone. It is usually (depending on operator) a separate number for data traffic. A

special ring signal should sound and the display should show “data call” or similar. This

ensures that the SIM card works and that the subscription is OK.

 Configure the meter for GSM modem by connecting a computer to the instrument’s

“Computer” port. Start PQ Online, establish communication and go to

File - Unit Configuration. Under the tab Communication and “Ext. Modem… “ the speed

(bits per second) should be set to 9600 as required by both the Falcom and Sony Ericsson

modem. If Unilyzer 901/902 is used, the speed should be set to 9600 in “Computer port”.

Press ”Send” and confirm.

 Install the SIM card in the GSM modem. Attach the antenna, the modem cable between the

GSM modem and the measure unit (UP-2210 – “Ext. modem”, Unilyzer 902 – use special

modem cable), and the modem’s power supply.

 Check the LEDs on the modem when the power is connected. The yellow LED should light

up immediately with a firm light (it’s the power indicator). The green LED should light up

after a couple of seconds, and then, after an additional 10-20 seconds, start blinking with an

approx. 2 second interval. If the green LED does not start to blink there is something wrong

with the SIM card (wrongly installed or PIN code active).

 Disconnect the power supply to the meter, and then re-connect it to ensure that the new

settings have taken effect.

 Verify that communication can be established from a phone, or preferably from a computer

with PQ Online together with another modem. When the signals reach the GSM modem you

should see that the green LED blinks faster (1-2 times/sec). The green LED continues to blink

more rapidly as long as the connection stays open.

 If PQ Online calls but no communication can be established with the modem / unit the

antenna must be checked and possibly moved. If the modem is located in a basement or

screened space the antenna may have to be moved up or outside. If the location is remote

directional antennas are available as accessories.

 The reception can be verified by placing the SIM card in a regular cell phone and verifying

that you can call from the antenna’s position.
