![]() The quick start guide with the LS2208 scanner does not include the USB virtual COM port mode. Same deal with the USB "virtual" COM port - only 1 per host/PC). I have an app at the moment where I need two scanners (Two seperate test slots on 1 PC), where I have to implement it using the serial interface cable. While I have only used Symbol scanners you can only have one USB scanner per host. The call back then passes the scanned data to my main event case. I found an UnifiedPOS spec that detailed the properties / methods etc required to interface to the scanner (chapter 22 in version 1.7 of the spec - see ).įrom there I had to register a call back dynamic event that calls a VI that reads the data from the scanner when the scan event occurs. ![]() I then added an activeX container the the VI front panel and selected the OPOS Scanner Control. ![]() (easist way is to install their TESTSCAN App as the COM (Componet Object Model ) needs registering). To configure the scanner I had to Scan the IBM HAND HELD USB barcode and install the OPOS drivers on the PC. ![]() So it has an event structure with "OK", "Cancel" and "Key down" (To filter user input - eg discard letters) and a dynamic "barcode scan" user event. I have a dialog that prompts the user to enter or scan (if enabled) a barcode, & checks the data before returning. I have successfully used a Symbol (Now Motorola) LS2208 USB barcode scanner with events. ![]()
