FINCH II Display Hardware Lock Setting

Each FINCH II display is equipped with a Hardware Lock feature that protects the configuration settings from unauthorized changes. As a result of this feature, operators will be unable to modify the FILL and FALL alarm settings while using the Titan truck in the field.

This security measure can be set by qualified technicians from the FINCH display circuit board, ensuring that the configured settings remain intact and unaltered.

This Hardware Lock feature is controlled through the following two B-DIP switches on the FINCH circuit board: 

• B-DIP 1 (B1)
• B-DIP 4 (B4) 

Titan has recently released a FINCH firmware version that has additional functionally around locking out operators from being able to make any changes to the FINCH display, such as updating the FILL or FALL alarm settings. Depending on the Firmware version on your FINCH will depend on if both B-DIP 1 and B-DIP 4 need to be updated, or just B-DIP 4.

How to check your firmware version on your FINCH

The FINCH display goes through a bootup sequence each time you power on your Titan system. It will display a green F and a number. This is the firmware version. 

It will then cycle through numbers 0-9 and letters A-F.

The video below shows how the bootup sequence appears when you first power on your Titan system.

Complete the following Steps to enable the Hardware Lock feature: 

1.  Power on your Titan System. Notice the number that appears next to the letter F right when the system is powered on. That is the Firmware version currently programmed to your FINCH display. 

2.  Open the FINCH display enclosure by unscrewing the two screws securing the door.

3.  Locate the DIP switches on the circuit board.

4.  The steps differ slightly depending on which firmware version you have on your FINCH.

If you have FINCH Firmware Version:

3.1.3 or Higher:

• Set DIP B-1 switch UP (ON) to lock out the FILL and FALL configuration from the FINCH Display. 
• Set DIP B-4 switch UP (ON) to enable the FINCH display to connect with Titan's mobile applications. This switch also ensures no other DIP switch change can be made by unauthorized operators.

3.0.8 or Lower: 

• Set DIP B-4 UP (ON) to prevent any changes to the FILL and FALL alarms, display configuration using other DIP switches, and allows access to our upcoming mobile applications that connect through bluetooth to your FINCH displays. 
• DIP B-1 is NOT configured to do anything, so this switch does not need to be changed. 

5.  Once the proper DIP-B switches are updated, close the enclosure and secure the door by tightening the two screws.

6.  Power down the Titan System and turn it back on.

Once the power has cycled, no one will be able to make any alterations to the FILL and FALL alarm settings on the FINCH display.
