6.7.1 Connection Example with External Device <1:1 Communication with
Micro-Imagechecker>
Overview
The MCU and Micro-Imagechecker A200/A100 are connected using an RS232C cable. The results of
the scan are stored in the registers of the FP2/FP2SH2/FP2SH.
•
After the scan start code “%S C
R
” has been sent from the FP2 side, the scan result is returned from the
Micro-Imagechecker as the response.
Communication format settings for Micro-Imagechecker
To set the communication mode and communication format settings for the Micro-Imagechecker, select
“5: communication” under “5: ENVIRONMENT” on the main menu, and the set the following items.
No. Name Set Value
No. 51 Communication mode Normal mode

Key Point:
•
If “Del” is specified for the inval id processing parameter, zero suppression processing will be carried
out on the output data, and the output format will be changed. Always make sure “Repl. 0” is specified.
•
When outputting data to an exte rnal device, numerical calculation is required, so “Out” should be
specified for the “Numerical calculation” parameter.
•
With the above settings, the fol lowing data will be output from the Micro-Imagechecker.
