If you prefix the remote system, and another user is in the middle of controlling the system from another port, you will get a busy signal. The default is the telco “busy signal” (pulsing 440 Hz and 680 Hz). When the other user is done, you can then access the system.

Entering commands on the local serial port on the main CPU board

When controlling from the serial port, simply enter the string of command digits without any star “*”” or prefix “#xx” digits. Enter commands to the serial port can be done with a simple dumb terminal program like HyperTerm or the SRS graphic user front end program called CONFIG.

Unlock Codes

The control system can be configured to decode commands that require or do not require an unlock code. An unlock code is defined by the system administrator and can be any length from 3 to 20 digits. The system supports up to 20 different unlock codes. The first of these codes is the “master unlock”’ code.

The default SRS master unlock code is 138065.

Change the master unlock code to your own personal code.

If a command requires an unlock code, the unlock code is entered between the access digit(s) and the command. For example if the unlock code is 138065 and the user command to be executed is 123 you would enter…

* 1 3 8 0 6 5 1 2 3

The unlock feature has a smart timer. After the unlock code is entered, it resets a timer and allows commands that require an unlock code to be entered without an unlock code as long as the 5 minute unlock window is still open. This makes it easy for a system administrator to enter several unlock protected commands without having to enter the unlock command each time. Of course you can enter the unlock code with each command if you like.
