Consecutive same read data validation
Consecutive same read data validation is useful when increased data security is required—
in particular when you read poorly printed codes, codes with variable lengths and without
check digits, "fragile" barcode types.
To increase the reliability of the data transmitted, you can set the MicroBar NX to validate
the data before it is transmitted—it will only transmit data after a specified number of
successful consecutive reads have given the same result.
For certain "fragile" symbologies, you can also increase the reliability of the barcode data
transmitted by configuring the MicroBar NX to transmit data for codes of 1, 2 or 3 fixed
lengths only (
Ð
Symbologies - Barcode length and data security ).
By default, transmission occurs after a single successful read.
Increasing the number of consecutive same reads before transmission decreases the
decoding rate.
Single Read Before Transmission (*)
Compose number of consecutive same reads before transmission
Compose Number of Consecutive Same Reads
Before Transmission (maximum = 10)
Example
To make your MicroBar NX decode the same code successfully 5 times
before it can transmit it:
1. Scan Compose Number of Consecutive Same Reads Before
Transmission.
2. Scan 5 then scan End Selection (
