Network Setting
The network is set using the SignalFire Toolkit. The network, network group, and corporate ID (replaced
with Encryption) settings must match those of the gateway (and other nodes) in order for them to
communicate
Encryption
Starting with firmware version 0.50, 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 Pressure Scout 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 (6 to
16 characters) you would like to use. Note that keys may not contain spaces or angle brackets. Enter it and then
press Set. This will cause the Scout to drop its network, and only attempt to join networks that use the same
encryption key. 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 Scout 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.
