Integrating the Scanner With Your Host SystemProduct Reference Guide 95Integrating the Scanner With Your Host SystemYour scanner MUST be equipped with the correct hardware (interface board,cable, etc.) to properly communicate with your host system. Contact yourdealer for information if you have questions about your scanner’s hardwarecompatibility.You may also want to contact the dealer or your system administrator if youhave no record of how your scanner was pre-programmed at the factory. Scan-ners are typically programmed with the default settings for specific interfacetypes (see Appendix F, Factory Defaults on page 471 for more information);however, your scanner may have been custom configured with settings that areunique to your company or application.Once you know the scanner’s current settings, you can determine what changeswill be required to allow communication with your host system and/or optionalfeatures you choose to modify to customize your installation. After recordingthe modifications needed, finish reading this section, then turn to the appro-priate page and follow the instructions to program the scanner.When all scanner features are programmed to your satisfaction, the scanner isready to be placed into operation.Customizing Your Scanner’s OperationMost scanner programming falls within four general categories:General Scanner and Scale Features — features common to all interface types.Examples include beeper adjustments such as volume and length, read verifi-cation settings, etc.EAS Features — control the settings for initerfacing with the (optional) EASdevice.Interface Related Features — mandatory settings necessary to allow communi-cation with your host terminal. Examples of these settings are: RS-232 baudrate and parity.Symbology Programming — gives the scanner the capability to autodiscriminateas few as one, and as many as all available symbologies. For optimal scannerperformance enable only those symbologies required. Additionally the scannermay be programmed with the standard options available for the various sym-bologies, such as check digit, minimum label length, fixed and variable lengthbar codes, etc.If you experience difficulties, have questions or require additional information,contact your local distributor, or call your dealer or sales representative.CAUTIONIt is possible, via programming bar codes, to change the interface type(for example: from RS-232 to IBM Port 17). Great care should be takento select the correct interface type, since you can cause damage to thescanner and/or POS terminal by attempting to change to an incom-patible interface. ALWAYS make interface selections with the hostcable DISCONNECTED.NOTEEnsure that your planned modifications are compatible with the cur-rent interface. For example, baud rate selections are only valid in theRS-232 interface. The scanner will sound an error tone when scanningprogramming labels for features invalid to the current interface group.
