V500/V520 Bar Code Reader Protocol
Log Data Clear (V500) (Sequence No. 359 (Hex 0167))
This sequence clears the log data.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
Data Continuous Read (Scan) (V500) (Sequence No. 360 (Hex
0168))
This sequence performs the following operations repeatedly: Instructs the Bar Code Reader to start reading
and receives the data read by the Bar Code Reader. The scan notification method is used for the receive data.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
Receive data word allocation is similar to that of sequence No. 352 (Data read).
Note 1. Since this sequence repeats itself within the sequence, once it is executed, it remains in the execution
state until cancelled.
2. Even if execution is cancelled, the Bar Code Reader still keeps reading. Execute sequence No. 351
(BCR read stop) to end the sequence.
Note The reception wait time is not set for this sequence.
Data Continuous Read (Interrupt) (V500) (Sequence No. 361
(Hex 0169))
This sequence performs the following operations repeatedly: Instruct the Bar Code Reader to start reading and
receives the data read by the Bar Code Reader. The interrupt notification method is used for the receive data
and the interrupt No. is 100.
Send Data Word Allocation (3rd Operand of PMCR(260))
None.
Receive Data Word Allocation (4th Operand of PMCR(260))
The receive data word allocation similar to that of sequence No. 352 (data read).
Note 1. Since this sequence repeats itself within the sequence, once it is executed, it remains in the execution
state until cancelled.
2. Even if execution is cancelled, the Bar Code Reader keeps reading. Execute sequence No. 351 (BCR
read stop) to end the sequence.
3. The reception wait time is not set for this sequence.
4. Sequences No. 361 and No. 364 (Continuous Data Read with Interrupt) are not supported by the
CS1W-SCU@@(-V1) and CJ1W-SCU@@(-V1) Serial Communications Units. A protocol syntax error
will occur if an attempt is made to execute either sequence with a Serial Communications Unit.
BCR Initialize (V500) (Sequence No. 362 (Hex 016A))
This sequence clears the log data, confirms BCR connection and sets the BCR functions.
Send Data Word Allocation (3rd Operand of PMCR(260))
The send data word allocation is similar to that of sequence No. 354 (BCR Function Set).
Receive Data Word Allocation (4th Operand of PMCR(260))
None.
