Open Lock 
The OPEN function can be used to unlock a door that will not respond to a guest 
card or any master cards. It will even open a door that has missing or dead batteries. 
To OPEN a door with the XPP, follow these steps: 
1.  Connect the XPP to the lock and turn it ON. 
2.  Enter your password if applicable. 
3.  Select Open Lock using the arrow keys and press Enter. 
4.  If you are not using XPP operators, The message "Access Code:" will 
be displayed on the screen. Enter the Access code that was loaded into 
the XPP when the it was loaded from the computer, then press Enter.  
Power the Lock 
In the event that the batteries are dead in a lock, the XPP can be used to power the 
lock, which will allow you to use a keycard to open the lock. To do this, follow 
these steps: 
1.  Connect the XPP to the lock and turn it on. 
2.  Enter your password if applicable. 
3.  Select Power the Lock using the arrow keys and press Enter. 
4.  Use a valid key to open the lock. 
Use of this function would typically be by XPP operators who do not have access to 
the Open function. 
Clear Locking Plan 
When finished using the XPP, it is recommended that you use the Clear Locking 
Plan function to delete the information in the XPP. This should be done to protect 
the property in the event the XPP is lost or stolen. To clear the locking plan, follow 
these steps: 
1.  Turn the XPP on and enter your password if applicable. 
2.  Use the arrow keys to select Clear Locking Plan and press Enter. 
3.  Press Enter again to answer yes to the question ‘Are you sure?’. 
4.  All information about the locks will be erased from the unit. The test 
function and the power the lock function are still available to use. 
Communications Distributor 
The communications distributor is one of the most important pieces of the Onity 
system. Without it you cannot load the Portable Programmer or encode cards.  The 
communications distributor converts signals from the serial port of a computer to a 
secure proprietary communications network called HTCOM.
