• Reconnection Delay – defines time between each reconnection attempts.
• TCP IRT - defines TCP Initial Retransmission Timeout. In some cases,
extending this timeout may be helpful in case of slow connections, but the
default setting is recommended.
• TCP Max. Ret. - defines maximum reconnection attempts performed within
a simple connection cycle. In some cases, setting higher value may be
helpful in case of slow connections, but the default setting is recommended.
15.2.3 Configuring connections – Modem Connection
The Modem Connection position allows you
to configure several parameters to establish
internet connection.
Note: For connection with the SvanNET server the parameters in the Modem Connection list should
be set on default values as is shown on the screenshots above and below.
The Modem Connection screen contains the following positions:
• Server Address – allows you to enter up to 32 characters of either IP or
domain address, where the registration data will be sent during the
registration process (Data Protocol: TCP S or UDP) or to which the modem
will connect to (Data Protocol: TCP C). By default, the server address is
app.svannet.com and all other settings, presented in this chapter, are
default settings, which enabled the connection with the SvanNET server.
• Data Port – allows you to enter up to 5 characters for the port number. This
number denotes a port on which a communication socket will be configured
for data exchange between the remote host and the station.
• Registration Port – allows you to enter up to 5 characters for the port
number. This number denotes a port on which a communication socket will
be configured to transmit registration package (Register Mode: On) or
exchange Http data (Register Mode: AS or SMT. AS).
• APN – allows you to enter up to 20 characters of APN name of the SIM card
used with the modem.
• APN User – allows you to enter up to 20 characters of user’s name used for
verification by the SIM card used with the modem.
• APN Password – allows you to enter up to 20 characters of password used
for verification by the SIM card used with the modem.
• DNS Server – allows you to enter up to 15 characters of IP address of DNS
server used for establishing connection with the internet. In most cases,
leaving the default value of “0.0.0.0” will be sufficient, but some SIM cards
may require a specific address to be entered.
