getsequencetimes@@ Toff1 Ton Toff2
Where:
@@ represents the Fiber number and is a value in the range 01 – 20.
Toff1 represents the time the LED is off at the beginning of the sequence.
Ton represents the time the LED is on during the sequence.
Toff2 represents the time the LED is off at the end of the sequence.
Description
This command returns three time intervals for Fiber##. The times are in milliseconds and
represent the time the LED is 'off' at the beginning, the 'on' time and the 'off' time at the end
of the sequence. A valid capturesequence command must be issued before this command in
order to get valid data. The resolution of the times Toff1, Ton and Toff2 depends on the
sequence capture and sequence wait time settings.
Example:
The PC transmits getsequencetimes01 to the LED Analyser to instruct it to output the time
intervals for Fiber 01.
getsequencetimes01
Toff1 = 00350ms Ton = 00340 ms Toff2 = 76910ms
