DS2400 DATALOGIC 2.2 MECHANICAL INSTALLATION DS2400 can be installed to operate in different positions. The four screw holes (M4 x 5) on the body of the reader are for mechanical fixture (Figure A, 5 ). The diagrams below give the overall dimensions of the scanner and mounting bracket and may be used for installation. Refer to par. 2.5 for correct positioning. Figure 2.2 - DS2400 Overall dimensions 2.
DATALOGIC DS2400 2.3 JUNCTION BOX INSTALLATION The Junction Box provides a passive connection between your scanner and the outside world in a fast and practical way. It represents an alternative to the 25-pin connectors. Figure 2.3 shows the basic layout of a scanner using the junction box. Junction Box DS2400 Scanner cable System cables Figure 2.
DS2400 DATALOGIC The Junction Box is designed to be mounted to a panel of metal, plastic or other appropriate material using the mounting screws provided in the package. To do this: 1) Open the junction box by unscrewing the 4 cover screws. If necessary, using the two mounting holes inside the junction box as a pattern, mark the panel with an appropriate object and then drill two small pilot holes in the panel. Figure 2.
DATALOGIC DS2400 2.3.2 Junction Box Electrical Connections The connection and wiring procedure for Junction Box is described as follows: 1) Open the junction box by unscrewing the 4 cover screws. 2) Pass all System cables through the glands in the junction box housing. 3) To connect the power and input/output signals: • Prepare the individual wires of the system cables by stripping the insulation back approximately 11 mm.

Rubber seal J1 Scanner cable Figure 2.
DS2400 DATALOGIC 2.4 ELECTRICAL CONNECTIONS DS2400 25-pin connector models are equipped with a cable terminated by a 25-pin female D-sub connector for connection to the power supply and input/output signals. The details of the connector pins are indicated in the following table: Figure 2.
DATALOGIC DS2400 2.4.1 Power Supply Power can be supplied to the scanner through the pins provided on the 25pin connector used for communication with the host: USER INTERFACE DS2400 13 VS V+ (10 - 30 Vdc) 25 GND 1 CHASSIS VGND CHASSIS Earth Ground Figure 2.11 - Power supply connections The power must be between 10 and 30 Vdc only. It is recommended to connect pin 1 (CHASSIS) to a common earth ground. 2.4.
DS2400 DATALOGIC RS232 Interface The serial interface is used in this case for point to point connections; it handles communication with the host computer and allows both transmission of code data and the programming of the scanner. This is the default setting.

DS2400 DATALOGIC The Pitch angle is represented by the value P in Figure 2.24. Position the reader in order to minimize the Pitch angle. DS2400 Figure 2.24 - Pitch Angle The Skew angle is represented by the value S in Figure 2.25. Position the reader to assure at least 10° for the Skew angle. This avoids the direct reflection of the laser light emitted by the DS2400.
DATALOGIC DS2400 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.
DS2400 DATALOGIC 2.6.2 Pass Through Pass through mode allows two or more devices to be connected to a single external serial interface. Each DS2400 transmits the messages received by the auxiliary interface onto the main interface. All messages will be passed through this chain to the host. When On-Line Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object enters its reading zone.
DATALOGIC DS2400 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.
DS2400 DATALOGIC 2.6.4 RS485 Master/Slave 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 multidrop address in the range 0-4. The master scanner is also connected to the Host on the RS232 auxiliary serial interface.
DATALOGIC DS2400 NOTE The auxiliary serial interface of the slave scanners can be used in Local Echo communication mode to control any single scanner (visualize collected data) or to configure it using the WinHost utility or Host Mode Programming procedure. The termination resistors of the RS485 bus must not be installed. 2.6.5 Multiplexer Each scanner is connected to Multiplexer (for example MX4000) with the RS485 half-duplex main interface.

DATALOGIC DS2400 3 READING FEATURES The number of scans performed 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 motion direction (Figure 3.
DS2400 DATALOGIC For example, the DS2400 (800 scans/sec.) for a 25 mm high code moving 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.
