  • Page 28: Main Serial Interface

    EIA RS232 EIA RS485 NON POLLED EIA RS485 POLLED (for connection with a Datalogic multiplexer) 20 mA PASSIVE CURRENT LOOP DS41 automatically recognizes the type of interface selected at each power on of the scanner. If the recognized interface type is not compatible with the current communication handshaking, then the system forces the XON/XOFF protocol.

  • Page 29: Rs232 Interface

    DS41 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 configuration of the scanner. This is the default interface.

  • Page 30: Rs485 Non Polled Interface

    DATALOGIC DS41 Figure 2.16 - RS232 control signals The RTS232 and CTS232 signals control data transmission and synchronize the connected devices. If the RTS/CTS handshaking protocol is enabled, the DS41 activates the RTS232 output to indicate a message is to be transmitted. The receiving unit activates the CTS232 input to enable the transmission.

  • Page 31: Rs485 Polled Interface

    The RS485 POLLED interface is a Half Duplex (3 wires + shield) interface. The POLLED configuration can be used for multidrop connections with a Datalogic multiplexer or it can also be used for a master-slave layout (see paragraph 2.9.1). The following pins of the 25-pin connector are used for RS485 POLLED...

  • Page 39: Positioning

    DS41 DATALOGIC The WRONG output is used either for "Verifier" mode or for PCS control (PCS control is available for DSP models only, see paragraph 1.3). For Verifier this output activates when the decoded code does not correspond to the one set in the configuration. For PCS this output activates when the PCS level is below the threshold value.
  • Page 40 DATALOGIC DS41 Figure 2.30 - Pitch angle The Skew angle is represented by the value S in Figure 2.31. Position the reader to assure at least 10° for the Skew angle. This avoids the direct reflection of the laser light emitted by the DS41.

  • Page 41: Typical Layouts

    DS41 DATALOGIC TYPICAL LAYOUTS The DS41 barcode reader was specifically designed for industrial applications. A typical use is real time identification of moving objects on conveyor belts. A photoelectric sensor used as a code presence sensor signals when an object enters the scanner reading zone (see Figure 2.33).

  • Page 42: Master-Slave

    DATALOGIC DS41 2.9.1 Master-slave The master-slave layout is used to collect data from several scanners to build a multi-sided reading system; there can be one master and up to 5 slaves connected with the RS485 polled mode on the main serial interface.
