OPERATION OF
THE TERMINAL
3.1 FUNCTIONING
The DFM1000 will detect the bar code with a
single line laser beam. The reflected light will
be picked up and converted by the sensor to
an electric signal, which is representing the
bar code label. The decoder will recognise the
bar code symbology and extract teh informa-
tion. The resulting dta is sent to the host that
is connected to the scanner.
The presence of a bar code will be recognised
by the autotrigger function of the scanner,
meaning that the laser beam is activated as
soon as an object moves towards the reding
window of the laser scanner. When the user
prefers to use an external trigger, it is possible
to switch off the autotrigger function and con-
nect an external trigger to the scanner.

3.2 CHARACTERISTICS
The DFM1000 is equipped with different char-
acteristics. Some characteristics are already
preset by Opticon and have a function. A num-
ber of characteristics can be enabled or dis-
abled by the user through configuration soft-
ware and the configuration cable. In this chap-
ter we give you some examaples of the scan-
ners many functions.
3.2.1. Automatic triggering
Automatic triggering is a default function of the
scanner. When the user prefers to use an
external trigger, it is possible to switch off the
autotrigger funcation and connect an external
trigger to the scanner.
3.2.2. Adjustable scan width
If another scan width than the default scan
width is needed, it is possible to adjust the
reading width of the scan pattern settings.
3.2.3. Read modes
By setting an other read mode the use has
the ability to activate the read operation in the
that way that is the most convenient. the scan-
ner is provided with 3 read modes, which can
be enabled or disabled by the user;
Single read mode:
After a bar code is successfully decoded, the
laser is switched off, and the user has to
retrigger the scanner in order to scan the next
label.
Multiple read mode:
After a bar code is decoded successfully the
laser stays on, allowing the user to read
another bar code. A bar code is only transmit-
ted once, regardless the number of times the
scanner reads it. Only when the scanner could
not decode a bar code for a selected time, the
laser is shut off.
Continous read mode:
This is a test mode, in which every decoded
bar code is transmitted whether it is the same
or not.
