Section 6 - Encryption Code
Encryption Code
The Legacy system uses a 64 bit DES (Digital Encryption Standard) encryption algorithm to encrypt all audio in the system. The beltpacks in the system have a “key” in the software that the algorithm uses as the basis for the encryption. The same “key” must be used in all beltpacks on the system for communication to occur. The base station only relays the audio, and as such, does not need any encryption code set. The beltpack key can be anything from numbers to sentences to hexadecimal letters. For example the phrase, “The legacy system works great for our coaches”, could be the “key” for the encryption. The only criteria is the phrase/numbers/letters be no more than 80 characters long (this includes spaces and punctuation).
This encryption is active on all units from the factory and does not have to be “turned on” by the user. The user may want to change their key to something unique. This may be done by following the steps below:
Logging into a Beltpack (XO-1)
Computer Requirements:
Hardware
•Monitor
•Keyboard & Mouse
•Network card (10 BaseT or 100 BaseT)
•Ethernet straight thru or crossover cable (Use the green cable supplied with the system.)
Operating System
Microsoft® Windows® 95/98, NT, 2000, XP
Software
Telnet or similar application that lets you communicate to a specified IP Address (Most all computers have telnet or a similar program installed on them by default).
The following instructions use Telnet and Windows® 2000 to log into the beltpack. Other applications and operating systems will be similar.
1.Unplug any current
2.With the mouse, right click the My Network Places con, then select Properties.
3.Select Local Area Connection and then right click. Select Properties.
4.Select Internet Protocol (TCP/IP) and click on the Properties button.
5.Now select “Use the following IP address:” option. Make a note of your current settings on this screen (so you can place them back when done logging into the beltpacks).
Enter the following:
a. IP address: 192.168.1.40
b.Subnet Mask: 255.255.255.0
c.Default gateway: 192.168.1.1
6.Once the above information is entered, hit the OK button. Hit the OK button on the next screen out if needed. Depending on your computer, you may need to reboot the computer for the IP address changes to take effect.
7.Plug one end of the supplied green Ethernet cable into the computer.
8.Start a “command prompt” console window by clicking on “Start” then moving the mouse arrow to Programs, then Accessories and finally clicking on “Command Prompt”.
