Parameter Read Lock

CAUTION – Read locks can only be removed by using the value you entered or by returning the controller to ASI to unlock, subject to the shipping & RMA fees.

Read lock prevents users from reading parameter values. Two parameters are used to control read access functionality in the BAC controller.

Flash Parameter Read Access Code – Address 62

Parameter read access code – Address 498

To set Read Lock:

1. Enter a numerical integer code into the Flash Parameter Read Access Code. 
2. Save this value to flash.  
3. Power cycle the controller to enable the read lock. Most parameters including Flash Parameter Read Access Code will appear as ‘0’ after the power cycle to hide their value.

To unlock Read Lock:

1. Enter the same numerical code saved to Flash Parameter Read Access Code above to the Parameter read access code parameter to enable reading parameters. 

To remove or change Read Lock:

1. Enter the same numerical code saved to Flash Parameter Read Access Code above to the Parameter read access code parameter to enable reading parameters.
2. Change the Flash Parameter Read Access Code to your new desired value, or set it to 0 (default) to clear it.
3. Save to flash.
4. Power cycle the controller to enable the new read lock value.
