    Wand Emulation Connection In Wand Emulation mode, the scanner decodes the bar code then sends data in the same format as a wand scanner. The Code 39 Format converts all symbologies to Code 39. The Same Code Format transmits UPC, EAN, Code 128 and Interleaved 2 of 5 without any changes, but converts all other symbologies to Code 39.

  • Page 39: Wand Emulation Transmission Rate

    Wand Emulation Transmission Rate The Transmission Rate is limited by the terminal’s ability to receive data without dropping characters. Default = 25 inches/second. * 25 Wand Emulation Polarity The Polarity can be sent as standard with black bars high, or reversed with white bars high.

  • Page 40: Wand Emulation Idle

    Wand Emulation Idle The idle describes the state of the scanner when no data is being transmitted. When in Wand Emulation mode, you must set the scanner’s idle state to match the idle state for the device to which the scanner is connected. Default = Idle High .

    Delay Between Blocks This sets the delay time between data blocks. Default = 50ms. * 50ms 150ms 500ms Overall Checksum When this option is turned on, a computed check character is added at the end of the entire message. The check character is the character which when Exclusive-OR’d with every preceding character of the message yields a result of 0x00 (00H).

  • Page 43: Chapter 3 - Output

    Output Scan Rate Adjusting the scan rate changes the current draw when scanning. The slower the scan rate, the lower the current draw. (The standby current remains the same.) Scan speeds are 270 s/s, 135 s/s, and 67 s/s. A scan speed of 270 draws the highest power and has the best performance.

  • Page 44: Beeper Tone

    Beeper Tone Default = Normal. * Normal Beep Short Beep Scan Voting This sets the number of times the same bar code has to be read before it is transmitted to the terminal. Normal uses the default values listed for the sym- bologies in the Default Charts beginning on page 11-1.

  • Page 45: Reread Delay

    Reread Delay This sets the time period before the scanner can read the same bar code a sec- ond time. Setting a reread delay protects against accidental rereads of the same bar code. Longer delays are effective in minimizing accidental rereads at POS (point of sale).

  • Page 49: Chapter 4 - Data Editing

    Data Editing Prefix/Suffix Overview When a bar code is scanned, additional information is sent to the host computer along with the bar code data. This group of bar code data and additional, user-defined data is called a “message string.” The selections in this section are used to build the user-defined data into the message string.

  • Page 50: To Add A Prefix Or Suffix

    To Add a Prefix or Suffix: Step 1. Scan the Add Prefix or Add Suffix symbol (page 4-4). Step 2. Determine the 2 digit Hex value from the Symbology Chart (page 4-5) for the symbology to which you want to apply the prefix or suffix. Step 3.
