Where:
## represents the wait time in milliseconds (00 – 99 msec)
### represents the wait time in milliseconds (000 – 999 msec)
Description
This command is used to set the Wait time between captures. The Wait time can be set to any
value in the range 000 – 999 milliseconds. This Wait time is set for all Fiber Channels enabled
by the setSequencemode or putSequencemode command.
PutSequencewait commands are stored in RAM memory while SetSequencewait commands
are stored in Flash memory.
Example:
The PC transmits putsequencewait10 to the LED Analyser to instruct it to set the wait time
between captures to 10 msec. The LED Analyser will return a string OK to the PC.
putsequencewait10
OK
To determine what Wait Time between Sequence Captures is set to, use the command
getsequencewait . It will return a time in milliseconds.
