Network Setting
The network address can be used to create separate networks using multiple gateways (that are in
close proximity with one another). The network is set using the SignalFire Toolkit. The Network
Group setting is used when more than 8 networks are needed. Both
the network and network group must match those of other nodes
for nodes to communicate.
Encryption
It is possible to encrypt over-the-air transmissions to prevent tampering. Encryption keys replace the Corporate
ID system, so it is important that all devices connected to a Gateway have the same encryption key as well as
network and network group number.
To set up a Flow Totalizer to use encryption, click the checkbox labeled Enable Encryption inside the Set
Corporate ID box:
The encryption key box. For more details, click the Help button.
The box will then change into a Set Encryption Key box, and it will prompt instead for the encryption key you
would like to use. Note that keys may not contain spaces or angle brackets. Enter it and then press Set. If you are
setting up a new network, you will need to set the encryption key on all of your devices. If you are adding a Flow
Totalizer to a legacy network, you can simply set the Corporate ID without clicking the Enable Encryption box,
and it will remain compatible with the older system.
Setting the encryption key.
It is also possible to hide your encryption key so it cannot be read. This is the most secure option, but if you
forget your key, there is no way to recover it – you have to reset the key on every device on its network. To enable
this option, select Set Encryption Key Unrecoverable under the Settings menu.
Setting the encryption key unrecoverable.
