1. INTRODUCTION  
The 1U643 Breakout Box and Data Logger is a tool for monitoring aircraft systems by  
providing a test point breakout between various electronic modules and their associated  
interconnects with the aircraft. The 1U643 was designed as a dual purpose tool. The 1U643  
can be used stand alone as a normal breakout box or, when connected to a notebook  
computer via the RS232 serial port, as a data viewing, logging, and recording instrument.  
At the heart of the 1U643 electronics is the industry standard 80C552 processor which  
when connected to a notebook computer via RS232 serial communications becomes a very  
powerful diagnostics tool. The 1U643 data logger allows diagnosis of aircraft system  
malfunctions by enabling the user to record data from aircraft systems for later viewing by  
knowledgeable systems engineers or technicians.

The ‘Options’ menu has the following function:  
Select the serial communications port through which to receive data from the breakout box.  
The communications port selected must match the physical port to which the breakout box  
is connected. In order to properly communicate with the breakout box the serial port must  
be configured correctly. The default serial port is ‘Comm 1’. If the use of a different  
communications port number is desired or required, the selection must be made here each  
time the software is restarted. Please refer to the computer operation manuals for  
information regarding a particular computer serial port configuration.  
The ‘Run’ menu has ‘Start’, which starts data acquisition and ‘Stop’, which stops  
acquisition of data.  
The ‘View’ menu is used for loading or unloading the DC viewing window and for loading  
an Oscilloscope/Line Graph window. There can be one Oscilloscope/Line Graph window  
loaded for each breakout box pin.  
The ‘Window’ menu is used to automatically arrange the windows for easier viewing.

The ‘Help’ menu displays the ‘About’ window, which displays information such as the  
current revision of this software.  
5.1 DC Viewing Window  
Before viewing of acquired data can begin the user must select the mode of display. One  
method of viewing data acquisition is the DC viewing window.  
When ‘DC Volt’ is selected the DC Voltage Viewing window appears. It is unloaded  
in the same manner. The DC Viewing window can be turned on and off through the  
corresponding toolbar button. This window displays all pins simultaneously.

5.2 Oscilloscope/Line Graph Windows  
The Oscilloscope/Line Graph window is loaded through the View menu or through the  
corresponding toolbar button. Up to 39 such windows can be opened, one for each pin, if  
desired.  
The Pin # box determines which breakout box pin will be displayed on this window.  
Numbers can be entered directly into the box by clicking on it and typing the number, or by  
clicking the up or down arrows the number can be spun up or down. The Points box sets  
the number of samples to be displayed in one sweep of the line graph. The maximum  
number of points is 32000 the minimum is 1.

5.3 Starting Data Acquisition  
Once the mode of viewing has been set up the acquisition is started by clicking ‘Run/Start’  
in the menu or by clicking the corresponding toolbar button. If the Breakout Box power is  
on and the Communications port has been configured properly the display windows should  
show data.  
Note that the ‘VDC’ field in the upper right corner of the Oscilloscope window displays the  
DC Voltage of the last acquired data point for the corresponding breakout box pin selected.

5.4 Recording Data Files  
Recording of data can be started at anytime while data is being acquired by clicking on the  
toolbar button with the red dot.  
Once recording has begun it can be paused temporarily by clicking the pause button.  
Recording will resume by clicking pause again.  
5.5 Playback of Data Files  
To playback a recording that was just recorded simply click on the play button.  
The mode of display at the time of recording does not determine the mode of display at  
playback. All data is recorded. Therefore the mode of display can be setup however the  
user chooses and this is accomplished in the same manner as it was for acquisition. The  
user can pause playback at any point during playback of a recorded file by clicking the  
pause button. Playback is resumed by clicking the pause button again. It is also possible to  
play in reverse by clicking the reverse play button.  
Playback is returned to normal by clicking the reverse play button again.  
Once a recording has been reviewed the user can save it permanently by saving it to a  
permanent file. If the recording is not saved to a permanent file then that recording will be  
lost the next time a recording is initiated.

5.6 Saving Recorded Data Files  
To permanently save a recorded file it must save from the temporary record file to a user  
named file. To achieve this click on ‘File/Save As…’ in the menu or click on the  
corresponding toolbar button.  
The following dialog prompts the user to name the file. The file can be saved anywhere on  
the computers disk drives by selecting the destination directory, or if a network drive has  
been set up in the Windows operating system the user can direct the file there. The file  
‘temp.dat’ is the default filename for the temporary storage of the recording function and  
should not be used for permanent storage, as it will be overwritten.

5.7 Opening Data Files For Playback  
To playback a file other than the most recently recorded one the user must first open that  
file by clicking ‘File/Open’ in the menu or by clicking on the corresponding toolbar button.  
The user is prompted to select the file to open.  
Once the file has been opened the user must set up the display windows for viewing  
playback. Then by clicking on the ‘Play’ button on the toolbar the playback of the file will  
be initiated. The user can replay the file as many times as desired but once the ‘Stop’  
button has been clicked or the user declines to replay the file, the user selected file is closed  
and the default file ‘temp.dat’ is used.

5.8 Exporting Data  
It may be desirable to view and analyze data using another program such as a spreadsheet,  
and for this reason a data export function is included. The export data function exports data  
to a comma separated value (csv) file, which is compatible with most spreadsheet or data  
base programs. In order to export data the user must first open the recording for which  
exported data is desired. Then the user must click ‘File/Export’.  
The user is then prompted to enter a file name to export data to. The data is then exported.  
The csv file can then be loaded using a program of the users choice.  
6. TROUBLESHOOTING  
If the data logger program fails to receive data from the breakout box then the following  
should be verified:  
• The proper communications port has been selected under ‘Options’ menu.  
• The breakout box is powered on.  
• The RS-232 cable and connections are good.  
• There are no serial port IRQ conflicts on the computer (see computer documentation on  
setting up communications ports).  
• The Breakout Box is receiving the proper power from the aircraft or other power  
source.
