SECTION 9. INPUT/OUTPUT INSTRUCTIONS
PARAMETER 3. LOCATION
This parameter determines the starting input
location for the 'n' values to be returned to the
recorder. The 'M' or 'M1-M9' command issued
by the SDI-12 recorder determines if the
starting location is actually that specified in
Parameter 3 or a multiple of 'n' past Parameter
3.
Starting input location = Parameter 3 + (n*x),
where n is specified in Parameter 2, and, x is
the number following the 'M' sent by the SDI-12
recorder (1-9).If the 'M' command is sent by the
recorder x = 0.
Results of Instruction 106
The sensor CR10 will return a set of input
locations in response to the M or M1..M9
command sequence. The set of Locations
returned is determined by Parameters 2 and 3
of Instruction 106.
The three values, sent in response to a V
command sequence, indicate the status of the
sensor CR10. The first and second values are
from the *B mode of the sensor CR10, giving
the number of watchdog errors (E08) and the
number of table overruns that have occurred.
The third is a signature of the sensor CR10
memory. This signature is created by the same
technique that the Instruction 19 (Signature)
uses. The CR10 manual contains more
information on *B and Instruction 19.
In response to an I command, the sensor CR10
sends the string '10CAMPBELL CR10 001
aaaa' where aaaa is the number from the
eighth window of the *B mode.
