  • Page 19: Chapter 1. Getting Started

    The SE955 is a miniaturized, high performance laser based, single line, decoded bar code scan engine. Theory of Operation The SE955 is a scan engine combined with a microprocessor to control the functionality of the engine, perform software decoding of the bar code information and provide a communication link to the host computer.

    This deflection causes the laser spot to be scanned across the bar code. A feedback coil coaxial with the drive measures the amplitude of the scan element and is used to set the scan amplitude. The SE955 is factory calibrated to generate two user selectable scan angles, 35°...

    2. Mounting screws and locating pins must be non- magnetic material. Do not place any magnetic material within 1 inch of the SE955 chassis without testing. 3. Holes marked ‘A’ are mounting holes. Holes marked ‘B’ are scan engine location aids.

  • Page 29: Installing The Se955

    • Do not place magnetic material (e.g., dynamic speakers, ringers, vibrators, inductors, metal parts) within 1 inch of the SE955 chassis. The SE955 scan element used to generate the scan line has a magnet on one end. Locating magnetic or ferrous material near the scan engine may influence the pointing of the scan line emitted from the engine.

  • Page 211: Ssi Transactions

    Simple Serial Interface 10-27 SSI Transactions General data transactions ACK/NAK Handshaking If ACK/NAK handshaking is enabled, all packeted messages must have a CMD_ACK or CMD_NAK response, unless the command description states otherwise. This parameter is enabled by default, and should remain enabled to provide feedback to the host. Raw decode data and WAKEUP do not use ACK/NAK handshaking since they are not packeted data.

  • Page 212: Transfer Of Decode Data

    10-28 SE955 Integration Guide Transfer of Decode Data The Decode Data Packet Format parameter controls how decode data is sent to the host. When this parameter is set, the data is sent in a DECODE_DATA packet. When the parameter is cleared, the data is transmitted as raw ASCII data.
  • Page 213 Simple Serial Interface 10-29 ACK/NAK Disabled and Packeted DECODE_DATA In this example ACK/NAK does not occur even though packeted_decode is enabled because the ACK/NAK handshaking parameter is disabled. Decoder Host Data is captured by DECODE_DATA decoder message sent ACK/NAK Disabled and Unpacketed ASCII Data Data captured by the decoder is sent to the host.

  • Page 214: Communication Summary

    10-30 SE955 Integration Guide Communication Summary RTS/CTS Lines All communication must use RTS/CTS handshaking as described in Appendix A, Serial Interface Specification. ACK/NAK Option ACK/NAK handshaking can be enabled or disabled. This handshaking is enabled by default; disabling this is not recommended as it can lead to communication problems, since handshaking is the only indication that a message was received and if it was received correctly.

  • Page 215: Ssi Communication Notes

    There is a permanent/temporary bit in the PARAM_SEND message. Temporary changes are lost when power is removed from the SE955. Permanent changes are written to non-volatile memory. Frequent changes shorten the life of the non-volatile memory. Do not scan parameter bar codes and send parameters via SSI simultaneously. All parameters can be accessed via SSI, so parameter...

  • Page 217: Appendix A. Serial Interface Specification

    Serial Interface Specification Introduction 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. This specification does not impose any requirements on how the data is packaged and the number of characters exchanged.

  • Page 218: A Character

    Many communications packages do not properly use the handshaking lines for half duplex communications. If using a PC communications package such as Windows Terminal, disconnect the hardware handshaking lines from the interface. The software application libraries included with the optional SE955 Developer Kit provide code to perform proper handshaking. Table A-1 lists the decoder’s signal lines, and...

    Serial Interface Specification A-3 Figure A-1 shows the decoder and host signal relationships. Host RXD Host TXD Decoder Host Host CTS Host RTS Figure A-1. Decoder and Host Signals The Decoder This section describes the requirements that are specific to the decoder. Transmitting Data When the decoder needs to send information, it must first check the CTS line to see if the host is trying to transmit.
  • Page 220 SE955 Integration Guide Receiving Data The decoder can receive data whenever it grants permission to the host to send its data. If the host is transmitting data, the maximum character-to-character delay allowed is determined by the Host Intercharacter Time-out parameter. The decoder may discard any received data if the host exceeds this time limit.

  • Page 221: The Host

    Serial Interface Specification A-5 The Host This section describes the requirements specific to the host. Transmitting Data The host only transmits after receiving permission from the decoder. There is no limit to the number of characters per transmit. However, the maximum character-to-character delay cannot exceed the Host Intercharacter Time-out parameter. The HOST RTS signal must return to inactive at the end of transmission (unless the host wants to temporarily prevent the decoder from transmitting).
