Hand Held Products 3700 CCD manual Scanteam 3700 Software Description, Interface Port

Communication is achieved using full duplex, asynchronous serial ASCII through a bidirectional RS–232 connection to the host system. The host defines or sets the configurable features and controls the operation of the 3700. The 3700’s configuration may be stored in non–volatile memory.

Note: In this manual, the term “host” refers to any computer that communicates with the SCANTEAM 3700 through its RS–232 port. During the configuration procedure, the host can be the main computer which controls the entire application, or can be a PC which has been connected to the 3700 for just that purpose. The terms “host instrument,” “host equipment,” and “host device” all refer to the system in which the 3700 has been integrated and which communicates with, controls and configures the operating features.

1.2.1Interface Port

The SCANTEAM 3700 has one port for I/O and Power. The port is a 10 pin RJ11 modular female connector. Hardwire connection to the scanner motherboard is available for additional features Pin assignments and function descriptions are presented in Appendix B. Cables are available from Hand Held Products for evaluation of the 3700. Hand Held Products can provide custom cables for host integration. A modular connector was chosen as the standard configuration for ease in servicing the scanner once installed..

1.2.2Nonvolatile Memory

The 3700 contains nonvolatile FLASH memory which is used to store operating parameters configured by means of host serial commands. This memory is easily reconfigurable to modify or add symbologies, as well as to modify or add serial commands to emulate a currently installed scanner.

1.3SCANTEAM 3700 Software Description

SCANTEAM 3700 software employs Hand Held Products’ time–proven decoding algorithms, controls the microprocessor functions, selects the scanner ports, decodes the bar codes, and formats the serial output messages.

The 3700 standard default parameters can be easily reconfigured to meet most scanning requirements. Application–specific features and options are configurable through the RS–232 communications link to the host system.

The 3700 can be configured to autodiscriminate among the following bar code symbologies and their variations: Codabar, Code 39, Code 128, Interleaved 2 of 5, UPC and EAN. Most common bar code options, such as validating symbol length and optional check character, are supported and easily selected. Symbologies can be added from Hand Held Products’ library of decoding algorithms.

In addition to decoding selections; data output formats, such as preamble and postamble strings, and operating parameters are also configurable through the host RS–232 serial communications connection.
