Triggering Modes
Parameter # 0x8A
Choose one of the options below to trigger the scan engine. Bar codes
and option numbers are on the following page.
•
Scan (Level)
- A trigger pull activates the laser and decode process-
ing. The laser remains on and decode processing continues until a
trigger release, a valid decode, or the Laser On Time-out is reached.
•
Scan (Pulse)
- A trigger pull activates the laser and decode process-
ing. The laser remains on and decode processing continues until a
valid decode or the Laser On Time-out is reached.
•
Continuous
- The laser is always on and decoding.
•
Blink
- This trigger mode is used for triggerless operation. Scanning
range is reduced in this mode. This mode cannot be used with scan-
ners that support an aim mode.
•
Host
- A host command issues the triggering signal. The scan engine
interprets an actual trigger pull as a Level triggering option.

Time-out Between Same Symbol
Parameter # 0x89
When in Continuous triggering mode, this parameter sets the mini-
mum time that must elapse before the scanner decodes a second bar
code identical to one just decoded. This reduces the risk of accidently
scanning the same symbol twice. It is programmable in 0.1 second in-
crements from 0.0 to 9.9 seconds.
To set a time-out between same symbol, scan the bar code below. Next
scan two numeric bar codes beginning on page 8-71 that correspond to
the desired time-out. Single digit values must have a leading zero. For
example, to set a time-out of 0.5 seconds, scan the bar code below, then
scan the “0” and “5” bar codes. To change the selection or cancel an
incorrect entry, scan the Cancel bar code in

4.2.11
Beep After Good Decode
Parameter # 0x38
Scan this symbol to set the scanner to beep after a good decode.
Scan this symbol to set the scanner not to beep after a good decode. The
beeper still operates during parameter menu scanning and indicates er-
ror conditions.

Transmit “No Read” Message
Parameter # 0x5E
Enable this option to transmit “NR” if a symbol does not decode during
the timeout period or before the trigger is released. Any enabled prefix
or suffixes are appended around this message.
When disabled, and a symbol cannot be decoded, no message is sent to
the host.
