DFM1000
OPERATION OF THE TERMINAL
3.2 CHARACTERISTICS
The DFM1000 is equipped with different char­acteristics. Some characteristics are already preset by Opticon and have a function.A num­ber of characteristics can be enabled or dis­abled by the user through configuration soft­ware and the configuration cable.In this chap­ter we give you some examaples of the scan­ners many functions.
3.2.1.
Automatic triggering
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 informa­tion.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 con­nect an external trigger to the scanner.
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 scan­ner 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 transmit­ted 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.
10
Continous read mode: This is a test mode, in which every decoded bar code is transmitted whether it is the same or not.
Page 11
3.2.4.
Check mode
3.2.9.
Bar code polarity
U
SER’S MANUAL
DFM1000
To ensure the bar code is correctly decoded, there are 2 options, to be enabled by the user.
Redundant reading: A bar code is transmitted only when it is decoded successfully for a selected number of times.This number can be set by the user.
Check digit calucation: A calculation of the digits of the bar code should correspond with the check digit.
3.2.5.
Formatting the bar code data
When reading a bar code, some formatting can be done by the scanner.the user can configure this. Some examples are:
Some of the options many not be valid for all symbologies.
Enable required symbologies, disable all others Transmit start/stop characters on/off Transmit check digit on/off Case conversion Add character(s) as prefix and suffix Translate bar codes, like full ASCII code 39, ISBN, EAN etc.
3.2.6.
LED indicator
The LED indicator can light up red or green. They can light up as a separate colour or together (shown as orange light). As a default setting the indicator is defined as a Power LED (orange) and as a Good Read LED (green). The duration that it lights after a successful decode or an other definition of the setting can be configured by the user.
3.2.7.
Buzzer signal
The buzzer signal, i.e.single tone beepe can be used for a good read bar code or as an error signal for a failed transmission.The definition of use, frequency and duration of the beeper can be adjusted by the user.
3.2.8.
Serial communication
For direct communication between the scanner and the host the scanner is provided with RS232 interface.Other interfaces are available on request.
The laser scanner is able to red positive and negative labels, for both black or coloured labels.The following bar code reading options are available:
Black on white White on black
3.2.10.
(No) Decode signal
Except for the Good Read LED, its is possible to indicate the results of bar code reading and decoding by a pulse signal to the host.
Dedoce pulse: the bar code is read and
decoded correctly No Decode pulse: during the read time no
bar code is detected or could not be
decoded
3.2.11.
(No) Decode message
When the read time expires and the scanner did not detect or decode a bar code, a configurable string of max. 50 characters can be transmitted to the host.
(supported from software version DCCV0103 or higher)
3.2.12.
Trigger signal
If internal trigger is activated, a positive or negative pulse is generated.This option can be set for each symbology separately or for all symbologies.
(supported from software version DCCV0103 or higher)
3.2.13.
Trigger message
A configurable string of max. 50 characters can be sent to the host when the scanner is triggered.
(supported from software version DCCV0104 or higher)
3.2.14.
Data formatting options
Data can be manipulated before the data is transmitted to the host.The data manipulation is performed unconditionally. See configuration disc for the specifications.
(supported from software version DCCV0110 or higher)
