12.1.1 Establish cellular service
For better security, we recommend using Konect PakBus® Router with a private dynamic IP
address. This method allows only incoming PakBus communications. No other incoming
communications are supported. However, all forms of outbound communications from the data
logger are supported, including but not limited to PakBus, email, and FTP.
Private dynamic IP addresses are standard with Telstra SIMs if no additional services have been
provisioned on the account by a Telstra partner.
NOTE:
When the data logger is connected to both Ethernet and a cellular modem, IPRoute() may
be used to specify which interface to use for the outbound communications, such as email,
FTP, and HTTP.
A public static IP address can also be used. This provides more incoming communications
functionality, but is less secure and more vulnerable to unsolicited traffic.
12.1.1.1 Selecting a data service
Before installing a data logging system with telemetry, you will need a SIM card and data plan.
For most applications, Telstra will offer the best coverage, especially in regional areas. Telstra and
Optus coverage maps can be found on each provider's respective websites.
The CELL220 and CR300-CELL220 will work with standard data plans. No extra steps are
necessary because of the complimentary Konect Pakbus Router service. A micro-SIM (3FF) is the
correct size for use with the CELL220.
