Section 6 - Encryption Code and Password

Encryption Code

The BTR/TR-24 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” 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 BTR-24 system works great for our customers”, 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 running on all units from the factory and does not have to be “activated" by the user. The user may want to change their key to something unique. Please see the "Logging into a unit" instructions in this section for details on changing the encryption key.

Login Password

When a user logs into a beltpack or base station, he or she must enter a user login and password in order to proceed to the user menu.

•Login: telex

•Password: legacy

The login of "telex" cannot be changed, but for increased security the password can be changed via the user menu. Please see the "Logging into a Unit" instructions in this section for details on changing the password.

Software Version

Below the password prompt on the user configuration menu screen (See Figure 6-1), the software version of the unit is displayed. Pay close attention to the revision letter and the date. These are the two items that change if the software changes. The line below the software version indicates the system type. All the units should indicate TR-24/BTR-24 on this line.

In addition to the software version being displayed on the user configuration screen, if a beltpack is booted in wired mode, it will announce the software revision letter one second after the "wired" voice prompt is heard.

Logging into a Unit

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 RJ-45 network connections from the computer.

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”.

9.Press and hold down the “2” button on the beltpack. Keep holding the “2” button and turn-on the beltpack. Hold the beltpack button down until the green LED next to the “2” button lights up (about 20 seconds), then release button (Places the beltpack in wired mode).
