Blocking Execution from Certain Ports

Purpose of these commands:

The following three commands allow you to mark certain commands so that they can not be

executed from certain ports. You might want to use this command to make it so your autopatch

can not be accessed from the link ports. If you are using one of the ports as a control port, you

could make all of the commands in the controller so they could only be executed from that control

port. You could call these commands from the scheduler to disable some or all of the commands at

night. This adds a lot of security to your controller.

Caution:

Because these commands can keep you from executing commands, they can lock you out of your

own controller. If you have a terminal or computer hooked up to the serial port, these commands

can not lock you out, so you don't have to worry about it. Also, you can always re-initialize the

controller (see Appendix D), but that erases all of your programming and you have to be at the site

to do it. In other words, be careful what commands you block and what ports you block their

execution from. If you don't want to use these functions and you want to erase their names so that

they can not be entered accidently, enter the following commands:

Command 010 130 D or unkey or <Enter>

Command 010 131 D or unkey or <Enter>

Command 010 132 D or unkey or <Enter>

These commands erase the names of command numbers 130, 131 and 132 so that they can not be

executed without renaming them to a valid name.

If you think you have locked yourself out, execute the following sequence of commands from every

port you can get touch tones to, or from the serial port. If they are executed they will allow access

to every command from every port.

Command 131 1 000 999 D or unkey or <Enter>

Command 131 2 000 999 D or unkey or <Enter>

Command 131 3 000 999 D or unkey or <Enter>

Command 131 4 000 999 D or unkey or <Enter>

Command 131 5 000 999 D or unkey or <Enter>

Command 131 6 000 999 D or unkey or <Enter>

Command 131 7 000 999 D or unkey or <Enter>

Command 131 8 000 999 D or unkey or <Enter>
