Queries the delay parameter of the specified groups
of Delay. Returns to a string initiating from #. Data
head is to describe data length information starting
from #. For example, ##9000000017, the later 9
digits (000000017) following the initial 9 indicate
length of data flow (17 bytes).
The format of sequence parameter of each group is
“serial number, output state, delay duration”, and
parameter of each group is divided by
semicolon“;”.
For example: “2, OFF, 3;3, ON,1;” representing the
delay parameters of 2 groups; the serial number of
delay parameter of the 1
st
group is 2, output state is
OFF,delay time is 3S;the 2
nd
group is 3, output state is
ON,delay time is 1S.
