6.2.6 Data connection by GSM radio modem, Email and SMS transfer
If you like to transfer data or parameter of the viasis by GSM radio link you need
in common to obtain a second GSM radio modem for the communication with your
remote computer
. The radio modem must support CSD
protocol data communica-
tion. Further on you need two SIM cards of a provider, whose radio network
supports explicitly CSD data transfer with 9600 Baud data transfer speed.
For the use of E-mail data transfer and automatic viasis SMS alarm messages you need SIM
cards and contracts which include GPRS and SMS services. You may ask if the provider offers
contracts with data transfer only (without voice) services for business customers.
Before you obtain the SIM cards ask the provider if he covers the needed radio services
(CSD, GPRS, SMS) at the viasis measurement place(s) himself. Roaming service, the radio
service by a contractor of your radio service provider might be paid with high charges later on.
Regarding the questions „How to connect, install driv-
ers and setup your radio modem at your computer”,
please refer to the information given by the radio mo-
dem manufacturer. Finally a virtual COM port must
have been created in the Windows
Device manager
,
typical either in the device class
COM&LPT
or
Mo-
dems – Properties – Extended
, see also chapters 6.2.2
and 6.2.3.
Before you can connect with
viagraph
or another
minal software, check that the viasis is powered and the
radio modem is switched on by its related time
ule and (if needed) the PIN number of the SIM card is
set in the viasis, refer also to chapters 6.4.2.1 and
6.4.2.2.
In order to establish a connection with viagraph click
the button
Connect to device
see illustration 10 in the
viagraph start window.
After the modem was found the
Modem
screen is
shown, see also illustration 38. Enter the dialing num-
ber of the SIM card inserted in the viasis in the field
Number
. In the
Comment
field enter a unique descrip-
tion for the viasis.

Laptop or notebook integrated radio modems or “surf sticks” often offer an integrated modem with a virtual COM port for
various radio link protocols. But in almost all cases they do not provide CSD protocol capability . Therefore check if CSD
explicitly listed in the modem features in the provided manufacturer information.

CSD – circuit switched data

Viagraph expects a radio modem inserted SIM card with switched off PIN number request. This can be done by inserting
the SIM card in a mobile phone. Please follow the mobile phone manual, how to do it.
