CDRH 21 CFR 1040 at the date of manufacture. T he s canner is c lass ified as
a Class 2 laser product according to IEC 825- 1 regulations and as a Clas s II
laser product according to CDRH regulations.
There is a safety device which allows the laser to be s witched on only if the
motor is rotating above the threshold for its correct scanning speed.
The laser beam can be s witched off through a software c ommand ( see also
«Beam Shutter»
in the WinHost Help On Line).
WARNING
Use of controls or adjustm ents or performance of
procedures other than those spec ified herein may
result in exposure to hazardous visible laser light.

The parameters relative to the aux interface (baud rate, data bits, etc.) as
well as particular operating modes such as LOCAL ECHO can be defined
using the WinHost utility program installed fr om the diskette or "Host Mode"
programming provided on diskette.
The following pins of the 25-pin connector are used to connect the RS232
auxiliary interface:

The RTSAUX and CTSAUX signals control data transmission and
synchronize the connected devices. If the RTS/CTS handshaking protocol is
enabled, the DS2400 activates the RTSAUX output to indicate a mess age is
to be transmitted. The receiving unit ac tivates the CTSAUX input to enable
the transmission.
2.4.4 Inputs
The inputs available on the connector supplied with the scanner are the pins
relative to the External Trigger, as indicated below:
Pin Name Function
18 EXT TRIG+ External Trigger +
19 EXT TRIG- External Trigger -
The External Trigger input is used in the On- Line Operating Mode and tells
the scanner to scan for a code. The activ e state of this input is selected in
software. Refer to the WinHost Help On Line.
The yellow LED (Figure A, 2) is on when the External Trigger forces a
current flow through the EXT TRIG+ and EXT TRIG- pins.

2.6 TYPICAL LAYOUTS
The following typical layouts refer to system hardware configurations. Dotted
lines in the figures refer to optional hardware configurations within the
particular layout.
These layouts also require the correct setup of the software configuration
parameters. Complete software configuration procedures can be found in the
Guide To Rapid Configuration
in the WinHost Help On Line.
2.6.1 Point-to-Point
In this layout the data is transmitted to the Host on the main serial interface.
Host Mode programming can be accomplished either through the main
interface or the auxiliary interface.
In Local Echo communication mode, data is transmitted on the RS232
auxiliary interface independently from the main interface selection.
When On-Line Operating mode is used, the scanner is activated by an
External Trigger (photoelectric sensor) when the object enters its reading
zone.

2.6.3 RS232 Master/Slave
The RS232 master/slave connection is used to collect data from several
scanners to build either an multi-point or a multi-sided reading system; there
can be one master and up to 9 slaves connected together.
The Slave scanners use RS232 only on the main and auxiliary serial
interfaces. Each slave DS2400 transmits the messages received by the
auxiliary interface onto the main interface. All messages will be passed
through this chain to the master.
The master sc anner is connected to the Host on the main serial interface.
The possible main interface types for the Master scanner are RS232 or
RS485. (20 mA C.L. can also be used if the INT-22 accessory is installed).
Either On-Line or Serial On-Line Operating modes can be used in this layout.
When On-Line Operating mode is used, the external trigger signal is
unique to the system, however it is not necessary to bring t he external
trigger signal to the Slave scanners.
The main and auxiliary ports are connected as shown in the figure below.

The RS485 master/slave connection is used to collect data from several
scanners to build either a multi-point or a multi-sided reading system ; there
can be one master and up to 5 slaves connected together.
The slave scanners are connected together using RS485 half-duplex on the
main serial interface. Every slave scanner must have a m ultidrop address in
the range 0-4.
The master scanner is also connected to the Host on the RS232 auxiliary
serial interface.
The External Trigger s ignal is unique to the system; there is a s ingle reading
phase and a single message from the master scanner to the Host computer.
It is necessary to bring the External Trigger signal to all the scanners.
The main and auxiliary ports are connected as shown in the figure below.

3 READING FEATURES
The number of scans perf ormed on the code by the DS2400 and therefore
the decoding capability is influenced by the following parameters:
•
number of scans per second
•
code motion speed
•
label dimensions
•
scan direction with respect to code motion
About 5 scans during the code passage should be allowed to ensure a
successful read.
3.1 STEP-LADDER MODE
If scanning is perpendicular to the code m otion direction (Figure 3.1 - "stepladder" mode), the number of effective scans performed by the reader is
given by the following formula:
SN = [(LH/LS) * SS] – 2
Figure 3.1 - "Step-Ladder" scanning mode
Where: SN = number of effective scans
LH = label height (in mm)
LS = label movement speed
in (mm/s)
SS = number of scans per second
Technical Features -
3.1
DS2400 DATALOGIC
For example, the DS2400 (800 scans/sec.) for a 25 mm high c ode m oving at
1250 mm/s performs:
[(25/1250) * 800] - 2 = 14 effective scans.
3.2 PICKET-FENCE MODE
If scanning is parallel to the code motion, (Figure 3.2 - "pick et-fence" m ode),
the number of effective scans is given by the following formula:
SN = [((FW-LW)/LS) * SS] -2
Where: SN = number of effective scans
FW = reading field width (in mm)
LW = label width (in mm)
LS = label movement speed
(in mm/s)
SS = scans per second
Code motion direction
at LS speed
Laser beam
Figure 3.2 - "Picket-Fence" scanning mode
For example, for a 100 m m wide code moving in a point where the reading
field is 200 mm wide at a 2000 mm/s speed, the DS2400 (800 scans per
sec.), performs:
[((200-100)/2000) * 800] - 2 = 38 scans
