Complete Data Read (Sequence No. 353)

This sequence instructs the Bar Code Reader to start reading, receives the data read by the Bar Code Reader, stores the data in the receive data storage words, and then instructs the Reader to stop reading.

Send Data Word Allocation (2nd Operand of PMCR)

None.

Receive Data Word Allocation (3rd Operand of PMCR)

It is similar to sequence No. 352 (Data read).

Note The reception wait time is not set for this sequence.
