Beep After Good Decode
Determine if the unit beeper will sound during normal scanning. Usually it is
desirable to operate the unit with the beeper enabled. In all cases, the beeper
operates during parameter menu scanning and indicates error conditions. See
Beeper Definitions on page 4-17 .
Beeper Volume
Use this parameter to program the beeper for Full or Low volume.
Trigger Mode (for triggered models only)
Select whether you would like to use the scanner with the trigger (Triggered
Mode) for low power consumption, or if you’d like the laser to be in a constant
blinking state (Triggerless Mode) using continuous power. The Triggered
Mode has been designed for battery operation and is recommended for use
with portable terminals.
Decode Redundancy
Use this parameter to indicate whether the scanner must read a bar code one
time (LEVEL 0), two times (LEVEL 1), or three times (LEVEL 2) before
decoding it. A higher level of redundancy ensures the accuracy of a decode in,
for example, poor quality symbols.
Scan and Store (Code 39 Buffering)
When you select the scan and store option, all Code 39 symbols having a
leading space as a first character are temporarily buffered in the unit to be
transmitted later. The leading space is not buffered.
Decode of a valid Code 39 symbol with no leading space causes transmission
in sequence of all buffered data in a first-in first-out format, plus transmission
of the “triggering” symbol. See
Code 39 Buffering (Scan and Store) beginning on
page 4-19 for further details.
When the scan and transmit option is selected, decoded Code 39 symbols
without leading spaces are transmitted without being stored in the buffer.
