If you want your club members to be able to use the autopatch and remote base and do other

common things without logging on, but you still want your control operators to have to log on to

change how the controller is programmed, log on, enter the command sequence for Command 186

000 1 2. This sets user 000 to level 2. If you do this, everyone will be able to execute level 0, 1

and 2 commands without logging in.

If you want to turn the password system off, log on and enter the command sequence for

Command 186 000 1 7. This sets user 000 to level 7. If you do this, the controller will allow all

commands to be executed without logging on.

Before setting up the rest of the users, you should consider how secure you want your system to be

and choose from the following methods of logging into the controller. Before experimenting with

these methods, make sure that you are able to log on as at least TWO different users, both level

7. Otherwise if you mess up, you might not be able to log in. A secure system can lock you out

too!

Method #1 - No Passwords:

To log on with this method, you have to tell the controller your user number, but you don't have to

enter a password. This is useful when you want to require people to log on to execute commands

so you know who they are, but it doesn't provide much security. It is easy to log on as someone

else, because you don't have to know their password. To set up user 001 with no password, enter

Command 186 001 0. Use 001 can log on with Command 187 001.

Method #2 - Fixed Passwords:

We have already used this method in the examples above. With fixed passwords, you log onto the

controller by entering Command 187 followed by your user number and your password, for

example "187 001 1234". You can make your password up to eight digits long. For example,

using Command 186 001 1 7 0 12345678, user 001 is assigned a fixed password of 12345678.

Longer passwords are obviously harder to guess, but if someone is decoding your DTMF tones,

they will probably be able to figure out your password no matter how long it is. Even so, fixed

passwords are probably secure enough for most club members, and possibly secure enough for even

the owner and control operators.

Method #3 - Challenge Passwords:

When a user with a challenge password logs in, it takes two steps. First you enter the logon

command (Command 187) followed by their user number excluding the password information. The

controller looks the user number, finds out that the user is configured for a challednge password

entry, and issues the challenge by requesting the user to enter certain randomly selected digits of his

password. The user then re-executes Command 187 followed by those digits of the users password

that the controller asked for. An example will probably make this a lot more clear. You will have

to logon before trying this example, since command 186 is a level 6 command.
