4. Application Note 19 Barcode Readers P122685 Issue 1 Introduction The capabilities of the IrendView range of recorders can be extended by a Barcode Reader PCB option which allows the recorder to receive data from a standard compatible Code 39 barcode reader wand such as the Hewlett Packard HBSW 8300 Using IrendManager Pro a barcode description of up to 19 characters may be entered and the barcode printed out As the barcode is swiped by the wand it can set a Marker signal the beginning or end of an event eg beginning to use particular stocks or finishing those stocks An event in turn may trigger an effect such as Stop Recording Trigger options available are indicated in the TrendManager Pro Marker Effect dialog box The example on the next page shows a bar code for Start Batch 14780 which is swiped by the wand The event is added to the bottom of the Events List on the recorder The information is saved to disk then using TrendManager Pro the event of Start Batch 14780 is indicated on the graph Utilisation A Barcode Reader can be an effective mechanism in areas of Production Control User Operator ID Batch Control Work in Progress Reporting or as a Test Facility Its use is uncon strained in circumstances where a start and stop time may have to be recorded and identified as an event Elimination of human error in respect of eg transposing of figures may also be an influencing factor in the selection of this tool
