    INTRODUCTION 1 INTRODUCTION Datalogic introduces the newest addition to the Dragon™ Desk family of industrial scanners, the D151 Extra Long Range (XLR) reader. Robustness and ergonomics remain unsurpassed, as well as a clearly audible beeper and bright "good read" LEDs for areas where noise levels are normally high. The aiming system helps point to the right code.

    DRAGON™ D151 2 INSTALLATION Connections should always be made with power OFF! CAUTION DRAGON™ D151 INTERFACE CABLE CONNECTIONS The Dragon™ D151 reader can be connected to a Host by plugging an RS232 cable into the connector and closing the cable cover as shown below. To disconnect the cable, unscrew the cover screw, pull down on the front part of the cover and insert a paper clip or other similar object onto the cable connector while unplugging the cable from the Dragon™...

    RS-232 Baud rate is the number of bits of data transmitted per second. The reader's baud rate setting should match the data rate setting of the host device. If not, data may not reach the host device or may reach it in distorted form. BAUD RATE 300 BAUD RATE 600 BAUD RATE 1200...

  • Page 15: Parity

    RS-232 BAUD RATE 9600 BAUD RATE 19,200 BAUD RATE 38,400 ARITY A parity check bit is the most significant bit of each ASCII coded character. Select the parity type according to host device requirements. If you select Odd parity, the parity bit has a value 0 or 1, based on data, to ensure that an odd number of 1 bits is contained in the coded character.
  • Page 16 RS-232 If you select Even parity, the parity bit has a value 0 or 1, based on data, to ensure that an even number of 1 bits is contained in the coded character. EVEN Select MARK parity and the parity bit is always 1. MARK Select SPACE parity and the parity bit is always 0.

  • Page 17: Stop Bits

    RS-232 The stop bit(s) at the end of each transmitted character marks the end of transmission of one character and prepares the receiving device for the next character in the serial data stream. Set the number of stop bits (one or two) to match host device requirements.

  • Page 18: Decode Data Packet Format

    RS-232 Enable ACK/NACK Protocol When this option is selected, after transmitting data, the reader expects either an ACK or NACK response from the host. The reader also ACKs or NACKs messages from the host. The reader waits up to the programmable Host Serial Response Timeout to receive an ACK or NACK.

  • Page 19: Host Serial Response Timeout

    RS-232 ERIAL ESPONSE IMEOUT This parameter specifies how long the reader waits for an ACK or NACK before resending. Also, if the reader wants to send, and the host has already been granted permission to send, the reader waits for the designated timeout before declaring an error.

    DRAGON™ D151 A SERIAL INTERFACE SPECIFICATION PURPOSE The Serial Interface Specification (SIF) describes the requirements that two digital systems must meet to exchange asynchronous serial data. SIF deals only with the physical flow control and asynchronous serial transmission of data between two digital systems.
  • Page 95 SERIAL INTERFACE SPECIFICATION COMMON ATTRIBUTES This section describes requirements common to the reader and the host. Note: SIF is a half-duplex communication protocol. To maintain proper communication, the requirements in this section must be met. All SIF systems have four signal lines. Two are for handshaking and two are for transmitting and receiving serial data.
