Trigger reading
Reading starts by applying reading trigger
from outside.
This system is mainly used when operation.
When the external trigger signal is turned
on, laser radiates and starts reading. The
"Trigger controlled system" reads during
the trigger is ON, and the "Effective
duration designation system" reads only the
effective duration (*1) which is set
beforehand after the trigger is ON.
The upper equipment sends the
communication command and the laser
beam radiates to start reading. After
receiving the command, it reads only for the
effective duration (*1) which is set
beforehand.
Press the SCAN button once to read once.
Handy to use to check if the reading
condition setting is appropriate.
When the reading succeeds, the data is
output and ends reading automatically.
Reads bar codes continuously during the
trigger is ON or effective duration (*1).
When the first reading is completed, data is
once output and while reading the same
bar codes continuously, no output is made.
Outputs newly only when the data differ
from the adjacent bar code.
Reads bar codes continuously during the
trigger is ON or effective duration (*1).
Outputs data continuously even for the
same bar code.
Full-time reading
During the power is turned on, laser is
radiated all the time, to be able to read
any time. This system is mainly used at
installation and system testing.

(Ignored even when input.)
–
(Ignored even when pressed.)
Reads continuously and outputs the data
continuously.
The bar code reading continues in series.
While reading the same bar code, output
is not newly made. Outputs newly only
when the data differ from the adjacent bar
code.
Reads continuously and outputs the data
continuously.
