Datastream Functions

Figure 3.2: Datastream Screen

2Notice the following about the Datastream screen:

•Each line displays a data item. You use the Up and Down Direction keys to scroll through the data and to select lines.

•The screen’s data updates as the software reads from the vehicle’s ECU. Each update is called a “frame” of data.

•The function keys at the bottom of the screen let you perform several other functions on the screen. For details, refer to the next section, “Datastream Func- tions” on page 20.

•The status line above the function keys displays cur- rent software status information.

•You can stop and start the live readings at any time. When you stop the readings, the data “freezes” on the screen. For details, refer to “Freeze Frame” on page 25.

•The LED bar, directly above the status line, appears only when you use the More function key, LED Bar option. For details, refer to “Show / Hide LED Bar” on page 29.

3When you are finished using the screen, press the EXIT key to return to the Diagnostic Menu screen.

Datastream Functions

There are several functions you can use on the Data- stream screen. Most of the functions are activated with the function keys at the bottom of the screen. These functions, described in detail on the next few pages, include the following:

•Record and Playback – records the data for viewing again at a later time. (See page 21.)

•Graph / Analog / LED / Digital – depending on the type of data on a line, changes the view of a selected line from digital to graphical, analog, or LED. (See page 22.)

•To Top – moves a selected data item to the top of the screen. (See page 24.)

•Lock – locks selected data lines so they are always included when recording and printing, even if they are below the viewable area of the screen. (See page 24.)

•Freeze Frame – “freezes” the data acquisition and dis- plays past data. (See page 25.)

Note: The following functions are on the menu that appears when you press the More function key.

•Pathfinder – provides quick access to the Pathfinder soft- ware’s Quick Path functions from within the ABS / Air Bag software. (See page 25.)

•Print – prints the data in the viewable area of the current data display. (See page 26.)

•Zoom – enlarges the view of a data line. (See page 26.)

•Sort – rearranges the data alphabetically or with the LED and graphed lines at the top. (See page 27.)

•English / Metric Units – changes the units of measure for the data from English to Metric, or vice versa.

(See page 28.)

•Show / Hide LED Bar – displays a row of LED readings directly above the status line and function keys. The LED readings are for frequently monitored switches. (See page 29.)

•Show / Hide Analog – when analog gauges are dis- played at the top of the screen, temporarily hides the gauges or displays them again. (See page 30.)
