Specifications

The SD-1 is an in-line (wedge) bar code decoder designed to decode most of the popular bar code symbologies and convert the symbol data into ASCII characters and transmit those characters in RS-232 asynchronous serial format. The SD-1 can accept and decode bar code input from a hand-held wand (or light pen), from a bar code slot reader, and from most laser scanning devices or CCD scanners, and also can support an optional magnetic card reader.

The two RS-232 ports on the SD-1 allow for a number of interconnection possibilities, including direct connection to a host computer's serial port, or to a standard ASCII data terminal, or "wedged" into an existing serial link between a "dumb" terminal and the serial port on its host computer.

The operating environment for the SD-1 can be user programmed through the serial port or via a bar coded menu. Once established, the parameters are permanently stored in non-volatile memory for application at power-on.

Features

  • Connects to any RS-232 serial asynchronous device, data terminal, or computer port.
  • Scans and autodiscriminates all major bar code symbologies including UPC (A and E) EAN (8 and 13), Code 39, Interleaved 2 of 5, CODABAR, and Code 128.
  • Supports any digital wand or bar code slot reader, Track 1 or 2 magnetic stripe card reader (ABA Standard), and most decoded or undecoded handheld or stationary lasers and CCD scanners.
  • Audible "beep" and an L.E.D. signal with each valid decode.
  • User selectable options including enable/disable symbologies, minimum/maximum symbol length, pre/postamble keycodes, plus other operational selections.
  • Durable, high impact plastic wand with a replaceable sapphire tip. (SSW-40).
