Overview

Enabling SIO encryption will encrypt the traffic between SCP and the SIO with a 128-bit encryption key. Every 24 hours the SCP will generate a new 128-bit key. Series 3 SIO's support AES128 and AES256 bit encryption and is enabled by default when used in conjunction with an LP series or EP-4502 controller.

The following models support encrypted communication:

• EP-1502 min f/w 1.6.3
• EP-2500 min f/w 1.6.3
• MR-50 min f/w 1.37.3
• MR-51E min f/w Always Encrypted
• MR-52 min f/w 1.36.5
• MR-16IN min f/w 29.0
• MR-16OUT min f/w 29.2
• MR-DT min f/w N/A

Implementation

1. Navigate to the Hardware tree (Main | Hardware)
2. Select Installed SIOs
3. In the right hand pane, select the SIO that will be using encryption
4. Right click on the SIO and select Edit
5. Check the box Encrypt Communications
6. Click Save
7. Right click on the SIO and select Load AES Keys
8. The SIO will go into a communication failure.
9. If successful the SIO will report the communication status Normal/Encrypted
10. If the SIO does not report Normal/Encrypted edit and save the SIO

Removing Encryption

1. Navigate to the Hardware tree (Main | Hardware)
2. Select Installed SIOs
3. In the right hand pane, select the SIO that will no longer be using encryption
4. Right click on the SIO and select Edit
5. Uncheck the box Encrypt Communications
6. Click Save
7. If successful, the SIO will report the communication status Normal
