FEASA LED ANALYSER
FUNCTIONAL VERSION
Sequence Capture Mode
This is a simple procedure to use the Capture Sequence Mode in the Led Analyser. Each
command is detailed in the following section.
Capture Sequence Procedure:
Assumption: Blinking Led sequence to be tested here is blink 1 second on 1 second off.
Setup: Place the Led Analyser Fiber and Optical Head over the Leds to be tested.
1. Open Terminal window
2. Connect the Led Analyser.
3. Setup the sequence parameters, wait for the OK reply in each case..
Type - putsequencemode# (0 for All fibers, 1 for single fiber)
putsequencechannel## (## is Fiber Number, Use ONLY if 1 above)
- putsequencecapture100 (100ms, Capture Time depends on the Led Intensity)
- putsequencewait100 (100ms, Wait time between captures)
- putsequencenumber0050 (50, The number of captures or samples to store)
4. Perform a capture
Type - CS (Capture Sequence, Based on the info above the total
capture time here is 10seconds, (100ms+100ms)x
50captures))
5. Retrieve the Data.
Type - gethsiall (This will return the Hue, Saturation, Intensity for all
fibers, getxyiall, getwiall etc can be used as required.)
6. Interpret the data.
The results will be listed in the terminal window in columns for each fiber showing the
ON/OFF data.
7. Type - getfrequency## (## represents the fiber number)
8. Interpret the data.
The result will show 000.5Hz 050.0% (Frequency in Hertz, Dutycycle in %)
Note1: There are other data interrogation commands listed below.
