9. Advanced Operation

9.1 General

These guidelines will help you perform advanced operations on your radio.

9.2 Encryption

Your material is a valuable asset to your organisation and naturally you don’t want others

intercepting your radio signal. To do this, all that they need is a radio receiver that operates

in the same mode and on the same frequency you are using to transmit.

9.2.1 Encryption System

If the AES scrambling option has been purchased for the SOLO system in use, then it is

possible to encrypt the link. Both Bcrypt128 and BCrypt256 are licence-controlled features.

You’ll need to encrypt the traffic leaving the transmitter and set up the receiver for decrypt.

9.2.2 Switching on the Transmitter Encryption

Here’s how you set up Encryption on the device:

1. Connect your radio to your PC and run the control application (see Ch10, Control System)

2. In the Scrambling combo box click the drop-down arrow and select an encryption type.

(AES128 for example).

3. Click the Encryption button (yellow key icon).

4. The Write encryption key dialog box will open

5. In the Key type combo box click the drop-down arrow and select the key type you want

to write. (Should match the key type you chose in step 1).

6. In the AES128 key text box, type the encryption key you want to use.

7. Click the OK button.
