My Vista 20P Security Control Panel Cheat Sheet

To Reset Installer or Master code:
  • Disconnect battery from the panel.
  • Disconnect transformer from wall socket.
  • Keyboard panel should be dead now.
  • Connect transformer/AC.
  • Within 50 seconds press and hold the * and # keys simultaneously for 3 full seconds.
  • Connect battery.
  • "installer code 20" or "20" should show up on the LCD.
  • To Reset installer code: Press *20 followed by 4 digit installer code. Hear 3 beeps.
  • To set a new master code: [installer code] + 8 + 02 + 4-digit-master-code.
You can set other user codes now:

Add a user code: [Master Code] + [8] + user # + [New user code] + [New user again]
        user # 01 => Installer  (Installer can change installer code).
user # 02 => Master
        user # 03 => Partition 1 master
        user # 05 => could be a good new user.
        user 3 to 32 => defaulted to partition 1
             33 to 49 => defaulted to partition 2

Delete a user code: [Master Code] + [8] + user # + [#] [0]

Set Duress code (???): Master code + 8 + 32 + [new Duress code].
                       Master code + 8 + 32 + #13 => to authorize
                       (Now if [new Duress code] is input, it will attempt to dial, click 1/OFF button to disconnect)

Use *99 to exit (important).

Don't Use *98, which will lock down programming mode.

*97 => Reset factory defaults (3 beeps will follow)

Alpha Programming => Naming zone numbers to english words (so it would say FRONT DOOR)

ZONE PROGRAMMING -> Report codes should be 0 0 for own monitoring.

To ARM -> Master Code + 2
To DisARM -> Master Code + 1

Enter program mode: Master code + 800* (but all doors and windows must be closed)
        => successful (msg: 20)
*56 => Program zone properties (Set to Confirm 0=No,1=Yes, actually means 0=hardwired,1=RF)
       Enter Zn Num:

         If you used default then you just have to override these:
               Zone 1: 24-hr audible: Zone Type: 07
               Zone 5: Entry Exit #2: Zone Type: 02
               Zone 7: 24-hr Audible: Zone Type: 07
               Zone 1 to 8: Clear Report Code: 00*

Using XPerf

XPerf comes with Windows SDK. You can get it from MSFT website. During installation there is an option to install just the performance tools should you want only perf tools and not the whole SDK.

To collect a trace from administrator command line:
Begin your workload.xperf -on base+cswitch+power -stackwalk Profile -f c:\kernel.etl  Let the workload execute for a while.
xperf -stop If you have previously created c:\merged.etl, delete it.xperf -merge c:\kernel.etl c:\merged.etl  Now, before you can view your trace in UI, setup your symbol path:
set _NT_SYMBOL_PATH=<path to PDB files>  You should now be all set to launch the viewer:
xperf c:\merged.etl (this launches the viewer)  On the UI, there are several different type of graphs for various measurements. From inside the Graph menu, you can enable these views:

CPU Usage by Process.
CPU Sampling by CPU.
Stack Counts by type.

Happy XPerf-ing!

My AWS S3 crash course

Then navigate to Troubleshoot, and then choose Advanced, and then Command Prompt.

At prompt, change current directory to:
cd c:\ Then run these commands one by one to repair your boot sequence:
bootrec /fixboot bootrec /fixmbr bootrec /rebuildbcd During these steps it may ask you if a particular Windows partition is the right one to boot into, choose yes if it is.

Remove your recovery media, and reboot your computer. It should boot fine.
