SET/GET.
Yes.
Initiate a "discovery"command
#sdi *
#sdi
35385 sdi awmvD 0 0
Discovery is pending (D).
Detach A720SC Serial Cable and attach SDI-12 bus and wait for at
least 1 minute; the bus will be scanned.
Detach the SDI-12 bus, wait 2s and attach A720SC again. Proceed
with the following command:
#sdi
35385 sdi awmvd 1 0 M0 0xfffff 0
#
The answer indicates: 1 sensor found at address 0, method 0 and
index mask is 0xfffff (all 20 indices, 0-19).
Note: Every "1" in the index mask (binary), corresponds to a
selected index, e.g. 0x3 corresponds to index 0 and 1.
Example for three equivalent configuration commands:
sdi + 0 M0 3,4,5,9
sdi + 0 M0 0x238
sdi + 0 M0 0x230,3
The binary representation of 0x238 is: 1000111000b (bits 3,4,5 and
9 are set).
Returns a slot of SDI-12 sensor data, if any.
Offset and date/time, both optional. If an offset is specified, then
only the values after the offset are returned, all others are skipped.
