Selection of Operator - SIM card for Data
transfer
ClimaCheck and/or ClimaCheck distributors can supply SIM cards for most markets but due to the
operators pricing policies the roaming fees are often resulting in significantly higher rates so local
contracts can be cost-effective in some cases.
Requirement on SIM:
It must be configured and activated for GSM data communication which often require
some kind of “activation” by the operator even if the contract as such is including data
capability.
Typical amount of data for a standard system is 5-10 Mb of data per month depending on number
of channels and interval between data scans. Default is 1 minute when compressor is operating
and 5 minutes when compressor is off. To select operator with experience of data transfer Machine
to Machine (M2M) is recommended. Operators are using different settings in their network and it is
recommended to whenever possible use networks that offers
public IPs
to the connected devices
(many networks has a firewall disabling access from the outside). A Public IP means that the
ClimaCheck PA Pro can be contacted for configuration via Internet. The IP does not need to be a
fixed IP as the ClimaCheck on-line server monitors incoming traffics IP number. The sending IP is
displayed on the “Home page” for each system. If a SIM is set up to be behind the operators
firewall data can be sent out but configuration would have to be done with a locally connected PC
or through dial up connection, which is quite slow.
1.1
Setting up M2M communication
Experience shows that Machine to Machine (M2M) communication can be challenging to set up the
first time with a new operator.
Most operators are totally focused on the mobile telephone market. Even though smart phones use
data communication of the same type as in the M2M communication used by the ClimaCheck
Performance Analyser, it has proven that it’s difficult to get the correct configuration and
information required.
We therefor strongly advice first time set up with SIM from a new operator to
be done prior to going on-site to ensure functionality and avoid loss of time and
unnecessary travels.
Tests should preferably be done with the equipment to be used on site but the functionality of a
SIM and correct configuration can be tested with any ClimaCheck PA Pro and modem. By checking
that data is actually received on the ClimaCheck on-line server functionality can be validated
minimizing wasted time on site and return trips.
The information requested and how to enter it is described in
3.2 Entering APN and ISP phone
number
that should be required. Typically this is the “APN” address unique for each operator (this
is included in the configurations a mobile phone get when you first connect it to your operator).
This said the communication will not work if:
1.
The SIM card is not properly activated for data communication
2.
The PIN code is not removed from the SIM card before it is entered into the modem
3.
The Init string for modem is not sent from the PA Pro when UDP communication is
activated (only required with standard modem e.g. when router modem is not used).
