modem is waiting for the first connection to be established on a designated port (called
Data Port
; default 8001).
Such connection can come from any application - an initiator of the TCP connection (such as +) called
remote peer
. This mode is recommended as it gives the initiative to the application. This mode requires the SIM
with a
public address
(also called
public IP
).
The
TCP Server
mode uses a so-called
Registration
. This is a method of translation of a
dynamic address
to
a form of a static credentials. It is essential for effective use of a SIM card with a
dynamic IP
. The dynamic IP
means that the IP address is changed each time the modem establishes connection to the Internet. The
Registration feature allows to use the current internet address by an external application for the connection.
There are two Registration methods supported by SV 258 PRO:
1. DynDns
2. Address Server
The
DynDns
is a service that allows to translate a static name to the internet address. The special controlling
application uses this name to identify SV 258 PRO in the Internet as an internet address. The properly configured
station provides means to validate its internet address to be recognized in the Internet. The static name provided
by DynDns service is translated by the DNS protocol to a given internet address to which an application can
connect to.
Note: To use this method the user should have a DynDns account and to input its credentials
(host name, login name and password) into the SVAN 958AG configuration. For more details
regarding DynDns service consult http://www.dyndns.org.
The
Address Server
is a Svantek own initiative of providing the instrument's current internet address. In this
mode, SV 258 PRO provides its current internet address to Svantek server. + is getting said address
to be able to connect to it. This mode doesn’t require any payments for the account and obtaining any credentials
as it comes preconfigured to the user, but it requires access to
www.svantek.com
domain from the GSM
operator network.
Note: To use this method contact your local SVANTEK distributor.
5.1.2 SMS / E-mail alarming
SMS / E-mail alarming functionality allows the SV 258 PRO to inform the user about exceeded thresholds by
SMS and/or E-mail notification. SV 258 PRO can send an SMS to a defined number and/or an E-mail to a
defined address with alarm, including the current value of the monitored result against the threshold level.
The E-mail alarming requires the credentials of the e-mail server to be used for it, including the SMPT server
name, the port number, sender name, login and password. The content of the message is created automatically,
and the user can add his own information to it.
Note: SvanNET provides also an e-mail service. SVAN 958AG is factory configured to enable
e-mail sending via SvanNET. The user can reconfigure it through + only (see
+ User Manual).
SV 258 PRO stations support SSL (Secure Socket Layer) connections to e-mail servers that require encryption.
Note: SvanNET e-mail service uses SSL connection.
It should be noted that SMS alarming does not require the modem to establish internet connection and, as such,
the SIM card does not require any data transfer plan as sending SMS messages is done entirely over GSM
network. E-mails still require access to the internet.
