9.0 CONFIGURING THE DIGIDATA

The DigiData Fuel Airdata Computer comes configured from the factory for a particular

installation. The procedure contained in this Installation Manual is for software versions 93.10.75

and above.

9.1 Configuring Manually (Loop-back)

The unit is powered using the loop-back harness (consult drawing number 4028-716 contained in

section 10). The purpose of the loop-back harness is to tie the RS-232 transmit and receive ports

together. This allows the software, when the unit is powered on, to allow configuration of the unit

through the front panel switches and displays.

To enter the configuration mode:

1. Connect the special configuration harness to the DigiData and connect to power source.

2. Set the rotary switch knob to Airdata position and apply power to the unit.

3. After the unit has completed the Start Up self test mode, press and hold the TEST/ENTER

button until the DigiData enters the test mode. At the end of the normal test mode displays,

the unit will display “System Setup” and enter the configuration mode.

4. The ADD/FULL switch is used to page through the options per figure below. Use the USED

and REM buttons to scroll through the selections (or to increase/decrease the value in the case

of the K-Factors and Offsets and Low Fuel Warning).

5. Once all of the desired selections have been made, press and hold the TEST/ENTER button

until the message “Saving Changes” appears. The DigiData will reset, and the new selections

will now be in effect.

6. Power down unit and disconnect the configuration harness.
