Utilities
Read Rate Serial Utility Commands
Enter Decodes / Second Test
Sending <C> instructs the scanner to transmit the decodes per second and symbol data
(if any). The decode rate can vary dramatically due to the angle and location of the symbol
in relation to the field of view. This test is very useful in aligning and positioning the scanner
during setup.
Enter Decode Percent Test
Sending <Cp> instructs the scanner to transmit the percentage of decodes and any
decoded symbol data.
End Decodes / Second and Decode Percent Tests
Sending <J> ends both the Percent test and the Decodes/Second test.
PDF417 Information
Sending <a1> causes PDF417 data that is decoded in a triggered read cycle to be prefaced
with information about the symbol’s level of error correction (error correction level n),
number of rows (n rows), number of columns (n columns), number of informative code
words (n code words), and number of data bits (n data bits). This feature can be disabled
by sending <a1> again.
