For additional information on the significance of the SDI address, method and
index, please see also the SDI-12 standard specification (http:// www.sdi-12.org).
The digibyte is similar to the DATA command:

DESCRIPTION Sets/returns the maximum delay for waiting awake (i.e. out of sleep mode) for a
service request of an SDI-12 sensor. This parameter is set to 30 seconds by
default. A larger value may lead to higher power consumption. This should be used
in cases an SDI-12 sensor needs large time values to return a sensor result. If you
have such sensors and still want to use them, you need to change this parameter,
but please be aware of the fact that the RTU’s power consumption will be higher.
PARAMETERS Maximum wake time in seconds (1 to 999).
R
ETURNS The current value (in seconds).
