13-2 Data flow
The data flow between the IV-S20 and a personal computer is shown below.
[1] When the measurement execution processing code is 10, 11, 12 or 13
(1) Data flow when the measurement is started and the output of the results are controlled by
a general-purpose serial I/F signal
(2) Data flow when the measurement is started by a CCD trigger or a parallel I/F signal and the
output of the evaluation results are controlled by a general purpose serial I/F signal
- A response block can be specified in the settings on the [OBJECT TYPE I/O] menu. (See page
11·21.)
[2] When the measurement execution processing code is 18, 19, 1A or 1B
[3] Processing other than measurement execution processing
Any processing can be executed, irrespective of the input/output settings (measurement start input
and result output)
