Q: How Can I Keep Track of the Amounts of Data, in Order to Save Costs?
There are built-in registers that can be set up to generate alarms when traffic exceeds a specified limit.
For example, if the total bytes sent and received during the last 24 hours is more than 10,000,000 bytes,
you could use this to trigger an alarm.
Q: The Netbiter.net Server is Based in Sweden - is the Modem Making a Direct Con-
nection to Sweden?
No. The GPRS/3G connection is an Internet connection, so - depending on your subscription - you
will get a local connection to your local service provider. After that connection is made, it does not mat-
ter to which country the data is transferred.
Q: What is the Cost When Using "always connected" for GPRS?
This depends on the amount of data being sent and received. When connected to Netbiter.net, the Net-
biter Gateway will generate traffic to indicate that it is "alive" - this is limited to a few bytes, a couple of
times per hour. When using "always connected" there are settings for "Host to ping" and "Ping timer"
- if active these will also generate small amounts of traffic to keep the connection alive.
Q: What if Someone Starts Pinging my Fixed IP Address?
This will also generate data, the amount will depend on the type of attack.
Q: What Type of GPRS Subscription Should I Use - DHCP or Fixed IP Address?
For normal usage (logging and alarms) and viewing data on Netbiter.net, there is no need for a fixed IP
address.
If you need to connect directly to the Netbiter Gateway, to control and change values or settings, then
a SIM-card with a fixed IP address must be used.
Additional functions are being planned for Netbiter.net, so the need for a fixed IP address should be
minimized, and hopefully eliminated in the near future.
Q: How Can I Calculate the Length of Time Log Data is Saved?
Log size depends on the fol-
lowing parameters:
• the number of param-
eters being logged
• the format and
number of digits
(decimals, commas,
etc.) for each
parameter
• the sample time
For a log parameter with five
digits and a separating com-
ma, this will give 6 bytes per
log parameter. Each line also
contains the date and time,
which uses an additional 16
bytes per line.
