Securing the CPU with Data Encryption

If you have enabled encryption, the System

CONFIGURATION – DATA ENCRYPTION PAGE allows you to secure wireless data by using Data Encryption. This page offers two selections:

∙Enable check box

∙Encryption Key field

Data Encryption Enabled Check Box

This selection enables or disables Data Encryption on

CPU data packets.

Checked Enables Data Encryption. The two CPUs must share the same encryption key to exchange data.

Clear Disables Data Encryption. All CPUs with the same Subnet ID can exchange data.

Encryption Key and Retype Encryption Key Fields

Figure 31: Data Encryption Page

These items set the encryption key for the CPU.
