Read Rate Serial Utility Commands
Enter Decodes/Second Test
Sending <C> instructs the reader 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 reader
during setup.
Enter Percent Test
Sending <Cp> instructs the reader to transmit the percentage of decodes and any
decoded symbol data.
End Read Rate Test
Sending <J> ends both the Percent test and the Decodes/Second test.
