WI Series lets you set a system security code to help ensure the messages that your network
uses remain private. This provides an additional security layer to protect the system from
malicious access (e.g. hacking).
When security is enabled the WI-I/O 9-T uses the security code to encrypt all transmitted
radio messages and the WI-I/O 9-R will only receive messages encrypted with the same
security code.
Note
By default, the WI-I/O 9-L does not encrypt radio messages. You must enable security if
you want to encrypt radio messages.
The WI-I/O 9-L uses the security code to encrypt radio transmissions using 64-bit encryption.
All modules in the same system must use the same security code to encrypt and decrypt
messages or they cannot communicate with each other. The security code is downloaded to
each module when you download the configuration.
Note
You can download the configuration at any time. WI Series overwrites the old security
code if the new security code is different or the new configuration has no security code.
You can also remove the security code if required. For more information, see Removing the
security code on page 35.
To set the security code:
1. Open the project.
2. Select
Enable Security
3. WI Series automatically generates a random 8-character security code for the system.
You can use the random security code generated by WI Series or enter your own
code.
