Error Counters
Xfter Ovrflw Transfer Overflow. This counts the number of codes that were
lost due to an overflow in the transfer buffer between the
Decode/DSP processor and the reader/ARM processor.
Xfer BadLen Transfer Bad Length. Number of codes in the transfer buffer
than contained an invalid length, indicating some sort of
memory corruption.
QData@TX Queue Data at Transmit (non-tracking). This counter indicates
that the reader had not completed processing all of the scan
data at the user-specified transmit time. This will only happen
if the “transmit time” parameter is set to a value other than
zero. This does not necessarily indicate an error, but does
indicate that either the transmit time is too short or the reader
is seeing a lot of data which may be the result of too much
background noise.
QData@Trig Queue Data at Trigger (non-tracking). This counter indicates
that the reader had not completed processing all of the scan
data prior to the start of the next trigger. This typically can only
happen when the "transmit time” parameter is set to zero;
although it can also happen in conjunction with a Force
Transmit. As with the Queue Data at Transmit counter, this
does not necessarily indicate an error, but it likely indicates
that the reader is seeing a lot of data which may be the result
of too much background noise.
ForcedTx Forced Transmit (non-tracking). A forced transmit indicates
that the start of trigger occurred before the specified transmit
delay time had expired.
Lost Codes Lost Codes (tracking). If a bar code cannot be placed onto
any package while in tracking, the code is “lost” and this
counter is incremented. Lost codes are also reported in the
Monitor message window. Lost code occurrences typically
indicate tracking parameters need to be adjusted.
Missed Tx Missed Transmit (tracking). If a bar code is decoded after the
message for that package has been transmitted, the Missed
Transmit counter is incremented.
