4.39 OBRSetMultiStepReading
This function sets up step reading which is described below.
In the Device Emulator, it is not possible to retrieve multiple codes from the I/O Simulator.
Normal Read mode
There is no limit to the number of bar codes that can be scanned once OBROpen function has been
carried out to open and until OBRClose func
tion is carried out to close. When continuous scanning
is in operation, a repeated scanning on the same bar code will be avoided if the decoding result is the
same with that of the previous decoding result one scanning before.
Multi-step Read mode
Only the specified number of bar codes will be scanned once OBROpen function has been carried
out to open the scanning driver and until OBRClose func
tion is carried out to close. The number of
bar codes to be scanned is specified with OBRSetScanningCounter
function. When continuous
scanning is in operation, a repeated scanning on the same bar code will be avoided if the decoding
result is the same with that of the previous decoding result one scanning before.
