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.
2. HARDWARE/SOFTWARE REQUIREMENTS To use the 1U643 as a data logger/recorder the following is required: IBM or compatible Personal Computer with; 3. • RS-232 serial port • At least 1 Meg free hard disk space • Windows 3.1 or later INITIAL SETUP Insert 1U643 Data Logger Software Set up disk into computer and run the “setup.exe” program on the set up disk. Follow the instructions on the computer screen. Rev.
4. STARTUP To start viewing or recording data connect the computer to the 1U643 Breakout Box via an RS-232 Cable. Connect the breakout box to the aircraft system to be monitored per applicable aircraft system maintenance procedures. Turn on the power switch on the breakout box and then run the 1U643.exe program. The user will be greeted with a start up screen. At this point the user is given the option to ‘Continue’ or ‘Exit’. Rev.
5. SOFTWARE OPERATION After clicking ‘Continue’ on the start up screen the main program screen will appear. Please note the menu and toolbar at the top of the screen. Some of the toolbar buttons have matching operations, which can be accessed through the menu. From left to right the toolbar button functions are: • Open a recorded file for playback • Save a recorded file as *.
The status bar appears at the bottom of the screen. Included in the status bar are: • The present status of data acquisition • The time of day or when in play back mode the real time when the displayed block of data was recorded. • The number of data blocks received from the breakout box during the present acquisition run. Under the ‘File’ menu are the following items: • ‘Open’ Opens a previously recorded data file for playback • ‘Save As…’ Saves a recorded file as *.
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’.
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.
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.
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. Rev.
To allow for easier viewing of multiple windows the user can select ‘Window/Tile’ in the menu. The windows are automatically arranged in a tile fashion. Rev.
The windows can then be easily manipulated to allow the user to see the specific information of interest. Rev.
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.
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.
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.
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’.
