Where:
## represents the Fiber Number and is a number in the range 1 – 20.
all represents the 20 Fibers in a Feasa 20F, or 3 Fibers in a 3F.
XXX represents the dominant wavelength of the LED in nanometers.
YYYYY represents the intensity of the LED.
Description
This command is used to get the value of the Dominant Wavelength for the LED under the
Fiber number
## .This command should be preceded by the capture C command to ensure
valid LED data is stored in the memory of the LED Analyser. The C1-C5 commands are
available but are not as accurate. The data for each LED can be read out one-at-the-time, in
any order.
Alternatively use the getwiall command to read back the LED data for all 20 leds in
one command.
Example:
The PC transmits getwi01 to the LED Analyser to instruct it to send the stored dominant
wavelength & Intensity for the LED positioned under Fiber No 1. The LED Analyser will return
a string
xxx yyyyy to the PC.
