seconds or less. The response to each command has the form
atttn<CR><LF>
,
where
a
= the sensor address
ttt
= time, in seconds, until the measurement data is available
nn
= the number of values to be returned when one or more subsequent
D
commands are issued.
See the following example. A data logger has three sensors wired into terminal
C1
. The sensors are addresses X, Y, and Z. The data logger will issue the
following commands and receive the following responses:
TABLE
C-7.
Example aC! Sequence
XC!
The data logger makes a request to
sensor X to start a concurrent
measurement.
X03005<CR><LF>
Sensor X immediately indicates that
it will have 5 (05) values ready for
collection within the next 30 (030)
seconds.
YC!
The data logger makes a request to
sensor Y to start a concurrent
measurement.
Y04006<CR><LF>
Sensor Y immediately indicates that
it will have 6 (06) values ready for
collection within the next 40 (040)
seconds.
ZC!
The data logger makes a request to
sensor Z to start a concurrent
measurement.
Z02010<CR><LF>
Sensor Z immediately indicates that it
will have 10 values ready for
collection within the next 20 (020)
seconds.
ZD0!
After 20 seconds have passed, the
data logger starts the process of
collecting the data by issuing the first
D
command to sensor Z.
Z+1+2+3+4+5+6+7+8+9+10<CR><LF>
Sensor Z immediately responds with
the sensor address and the 10 values.
XD0!
10 seconds later, after a total of 30
seconds have passed, the data logger
starts the process of data from sensor
X by issuing the first
D
command.
X+1+2+3+4+5<CR><LF>
The sensor immediately responds
with the sensor address and the 5
values.
