Using the C200H ID Sensor Unit with CS1-series PCs

Program Example
Note Although the ID Busy flag normally turns OFF upon completion of the command, if the command execu-
tion flag is ON at this time, the ID Busy flag will stay ON. Therefore, design the program so that the com-
mand execution flag will be turned OFF when the ID Busy flag turns ON, as in the example.

numbers 10 through 14 (5 bytes)
If the number of bytes to be written to the Data
Carrier is odd, shift codes 2A and 0D forward
one byte and write 00 into the last 8 bits.
Write is executed.

At the same time, sets
the command storage
