Control modules
10.7.1
Module 10 – Activations
Description
The module defines the control signals for the reading operation of the barcode reader. It is
possible to select between standard reading operation and handshake operation.
In handshake operation, the controller must acknowledge the data reception via the ACK bit
before the new data is written into the input area.
After acknowledging the last decoding result, the input data is reset (filled with zeros).
