When enabled, the ASCII character set assigns a code to letters, punctuation marks, numerals, and most control keystrokes on the keyboard. The first 32 codes are non-printable and are assigned to keyboard control characters such as BACKSPACE and RETURN.

  • Page 60: Code 39 Buffering (Scan & Store)

    The leading space is not buffered. Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of all buffered data in a first-in first-out format, plus transmission of the “triggering” symbol.

  • Page 61: Buffer Data

    Parameter Menus Buffer Data To buffer data, Code 39 buffering must be enabled, and a symbol must be read with a space immediately following the start pattern. Unless symbol overflows the transmission buffer, the unit gives a lo/hi beep to indicate successful decode and buffering.

  • Page 86: Hardware Handshaking

    LS 2104 Product Reference Guide Hardware Handshaking The data interface consists of an RS-232C port. The port has been designed to operate either with or without the hardware handshaking lines, Request to Send (RTS), and Clear to Send (CTS). If Standard RTS/CTS handshaking is selected, scan data is transmitted according to the following sequence: The controller reads the CTS line for activity.
  • Page 87 Parameter Menus Scan the bar code below if no Hardware Handshaking is desired. NONE Scan the bar code below to select Standard RTS/CTS Hardware Handshaking. STANDARD RTS/CTS When RTS/CTS Option 1 is selected, the scanner asserts RTS before transmitting and ignores the state of CTS.
  • Page 88 LS 2104 Product Reference Guide When Option 2 is selected, RTS is always high or low (user-programmed logic level). However, the scanner waits for CTS to be asserted before transmitting data. If CTS is not asserted within 2 seconds (default), the scanner issues an error indication and discards the data.

  • Page 89: Software Handshaking

    Parameter Menus Software Handshaking This parameter offers control of the data transmission process in addition to, or instead of, that offered by hardware handshaking. There are five options. If Software Handshaking and Hardware Handshaking are both enabled, Hardware Handshaking takes precedence. None When this option is selected, data is transmitted immediately.

    Parameter Menus Host Serial Response Time-out This parameter specifies how long the scanner waits for an ACK, NAK, or CTS before determining that a transmission error has occurred. This only applies when in one of the ACK/NAK Software Handshaking modes, or RTS/CTS Hardware Handshaking option. The delay period can range from 0.0 to 9.9 seconds in 0.1-second increments.

  • Page 95: Intercharacter Delay

    Parameter Menus Intercharacter Delay Select the intercharacter delay option matching host requirements. The intercharacter delay gives the host system time to service its receiver and perform other tasks between characters. The delay period can range from no delay to 99 msec in 1-msec increments.

  • Page 111 (e.g., characters per inch). Bar Height The dimension of a bar measured perpendicular to the bar width. Thickness of a bar measured from the edge closest to the symbol start Bar Width character to the trailing edge of the same bar.
  • Page 112 Character Set Those characters available for encodation in a particular bar code symbology. A digit used to verify a correct symbol decode. The scanner inserts the Check Digit decoded data into an arithmetic formula and checks that the resulting number matches the encoded check digit. Check digits are required for UPC but are optional for other symbologies.
  • Page 113 Continuous Code A bar code or symbol in which all spaces within the symbol are parts of characters. There are no intercharacter gaps in a continuous code. The absence of gaps allows for greater information density.
  • Page 114 The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative deviations from this value. Nominal Size Standard size for a bar code symbol. Most UPC/EAN codes can be used over a range of magnifications (e.g., from 0.80 to 2.00 of nominal). Parameter A variable that can have different values assigned to it.
  • Page 115 A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL is the reflectance factor of the background and RD the reflectance factor of the dark bars.
  • Page 116 A scannable unit that encodes data within the conventions of a certain symbology, usually including start/stop characters, quiet zones, data characters, and check characters. Symbol Aspect Ratio The ratio of symbol height to symbol width. Symbol Height The distance between the outside edges of the quiet zones of the first row and the last row.
