2 Operation of the analyzer

 If possible, before starting the process of recording, receive the GPS signal to synchronize the

analyzer time to UTC. This will ensure the least possible timing errors during the recording and

a fast tuning time in case of a temporary loss of GPS signal.

 In order to ensure the compliance of the whole measurement with requirements of IEC 61000-

4-30 in terms of time marking for devices of Class A, the internal analyzer clock must be syn-

chronized to UTC, and GPS signal must be available for the whole process of recording.

2.11 GSM communication mode

2.11.1 General information about GSM connection

Built-in GSM modem ensures wireless communication with the analyzer from almost any loca-

tion with Internet access. Similarly as in case of USB and OR-1 connection, this mode provides the

user with a full control of the analyzer - the user may view current data, start and stop recording,

read the data for analysis, etc. To use this mode, the analyzer must be equipped with a SIM card

of the following service parameters:

 General Packet Radio Service (GPRS)

 static public IP address,

 SMS option to send alarm messages.

The communication is performed in the following manner:

 the modem connects to a GSM network, and then log on to the Internet,

 the modem initiates TCP/IP server service with IP address assigned by the service provider.

Usually, the port number used by the analyzer is 4001. The analyzer is present in the Inter-

net with this IP and port.

 PC from which the user tries to connect with the analyzer via GSM modem must have ac-

cess to the Internet.

 "Sonel Analysis 2" software while searching for analyzers, tries to connect to those analyz-

ers that have IP number configured in the data base (additionally the user must enable

"TCP/IP over GSM" in program settings). Only port 4001 of a remote host is checked by

default.

 If an analyzer is found under typed address and its serial number match the serial number

of an analyzer is the database, then the device will be shown in the list of found devices.

 After connecting the communication will be performed via the Internet. After completing the

connection, the software closes the connection with the analyzer, which enters a "stand-by"

mode waiting for a client connection.

2.11.2 Modem Configuration

In order to configure the SIM card and modem in the analyzer, the user must obtain the following

data from the data transmission service provider:

 PIN code for SIM card

 PUK code for SIM Card - for emergency cases, when SIM card is locked after repeated

attempts of enter wrong PIN,

Note

Ordinary SIM card removed from a cell-phone cannot be used with the

analyzer. GPRS in the analyzer requires a non-standard static IP address

service, reserved only for a given SIM card. This static IP address en-

sures that the analyzer has one permanent address in the Internet. This

type of service is commonly used for transmission "machine-to-machine"

(M2M) used e.g. in industry transmissions for monitoring and exchanging

measurement data between devices.
