DS2100N REFERENCE MANUAL 3 3.4 USER INTERFACE The following table contains the pinout for standard RS232 PC Host interface. For other user interface types please refer to their own manual.
INSTALLATION 3 3.5 POSITIONING The DS2100N scanner is able to decode moving barcode labels at a variety of angles, however significant angular distortion may degrade reading performance. When mounting the DS2100N take into consideration these three ideal label position angles: Pitch 0°, Skew 10° to 30° and Tilt 0°. Follow the suggestions for the best orientation: The Pitch angle is represented by the value P in Figure 35. Position the reader in order to minimize the Pitch angle.
DS2100N REFERENCE MANUAL 3 The Tilt angle is represented by the value T in Figure 37. Position the reader in order to minimize the Tilt angle. T Figure 37 - Tilt Angle By using the ACB (Advanced Code Builder) software parameter, the tilt angle is less critical and can be decoded even if the scan line doesn’t cross the entire code. See par. 3.1 or the Help On Line for details. 3.6 TYPICAL LAYOUTS The following typical layouts refer to system hardware configurations.
INSTALLATION 3.6.2 3 Pass-Through Pass-through mode allows two or more devices to be connected to a single external serial interface. Each DS2100N 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.
DS2100N REFERENCE MANUAL 3 The main and auxiliary ports are connected as shown in the figure below.
INSTALLATION 3.6.4 3 RS232 Master/Slave The RS232 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 9 slaves connected together. The Slave scanners use RS232 only on the main and auxiliary serial interfaces. Each slave DS2100N transmits the messages received by the auxiliary interface onto the main interface. All messages will be passed through this chain to the Master.
DS2100N REFERENCE MANUAL 3 3.6.5 Multiplexer Layout Each scanner is connected to a Multiplexer (for example MX4000) with the RS485 halfduplex main interface.
READING FEATURES 4 4 READING FEATURES 4.1 ADVANCED CODE BUILDER (ACB) In addition to linear reading, the Advanced Code Builder (ACB) allows code reading by “stitching” together two partial reads of it. ACB is not as powerful as Advanced Code Reconstruction due to limits on tilt angle, speed and Multi-label function; but it is effective in the case of close-to-linear, small height codes, damaged codes, or poor print quality codes.
DS2100N REFERENCE MANUAL 4 4.1.1 Important ACB Reading Conditions • Do not use ACB for omni-directional reading stations. • ACB can be activated for each symbology independently from the others. • ACB requires that the code be in movement with respect to the scanner. • ACB requires fixed length barcode reading. • The codes read with ACB enabled must pass in front of the scanner one at a time.
READING FEATURES 4.2.1 4 Step-Ladder Mode If scanning is perpendicular to the code motion direction (Figure 44), the number of effective scans performed by the reader is given by the following formula: SN = [(LH/LS) * SS] – 2 Where: SN LH LS SS = = = = number of effective scans label height (in mm) label movement speed in (mm/s) number of scans per second Direction of code movement at LS speed DS2100N LH Laser beam Figure 44 - "Step-Ladder" Scanning Mode For example, the DS2100N (500 scans/sec.
