Deleting the Database from a Controller

Deleting a controller's database is a way of forcing a download to the controller. Also, if a controller has been used on a RS 485 channel, and still holds that database, it will be necessary to erase the database. A TCP/IP database will not download until the RS 485 database has been removed.

There are four ways of deleting the database from a controller:

1. From CBAS in Hardware View, locate and click the controller, then click Erase Database. CBAS must be in Real Mode with Normal communications to the controller. After rebooting, the controller will immediately download the database again.
2. From the Handheld, go to the Main Menu.
   • Hit 5 (not listed) then Enter
   • Hit Select to Delete
   • Follow instructions, cycle power to controller
3. Connect using HyperTerminal (That's another story)
   • Type the command: ERASEDATABASE
4. Using the Address Dials on an 8X, 16X, 32X, or 64X.
   • Set Red Dial address to 999.
   • Power up the board.
   • Change Red Dial address to 990.
   • Change Red Dial address to 900.
   • Change Red Dial address to 000.
   • At this point the controller would recognize this number sequence and erase the database.
   • It will ONLY work if the Red Dial address is 999 after a power up.
