Description
The LED Analyser can be used to test LED-based 7-Segment displays. To set up the LED
Analyser to interrogate a single 7-Segment display, fit fibers labelled 1 to 7 over segments a-g
on the 7-Segment display. See Figure 28 .
To set up the LED Analyser to interrogate an additional 7-Segment display, fit fibers labelled
11 to 17 over segments a-g on the additional display.
To interrogate the digit displayed on the first 7-Segment Display send the command get7seg1
to the LED Analyser. The LED Analyser will return the digit displayed. The LED Analyser will
return the character X when the displayed value is not recognized (0 to 9) .
To interrogate the digit displayed on the second 7-Segment display send the command
get7seg2 to the LED Analyser. The LED Analyser will return the digit displayed. Again, the
LED Analyser will return the character X when the displayed value is not recognized (0 to 9) .
Note:- it is not necessary to send any capture commands prior to using the get7seg1 or
get7seg2 commands.

The PC transmits get7seg1 to the LED Analyser and the Analyser will return the value of the
