Troubleshooting ******************************************************************************* * 1. OVERVIEW ******************************************************************************* The Symbol(R) Scanner COM port emulation driver Installation Utility installs to the target PC the drivers necessary for providing COM port emulation support for Symbol scanners. Using the emulated COM device, user mode application can interact with the scanner. Current driver supports only reading data from scanner device. Support for setting scanner specific features from application is NOT supported. This driver can be installed by running the accompanying installer. ******************************************************************************* * 2. CHANGES ******************************************************************************* Changes from 1.8.4 to 1.8.5: * WHQL certified driver. * Read total timeouts monitoring issue fixed in the driver. * Improvement in re-enumeration of device driver at the time of installation. Changes from 1.8.3 to 1.8.4(Beta): * Fix issue of missing data while doing event based read with Microsoft Communication activeX control. Changes from 1.7 to 1.8.3: * WHQL certified drivers * Option to change port number using 'Advanced Setting' of 'Port Properties' in system 'Device Manager' is supported in Windows 2000 and XP. * Bug fixes in Windows 98 driver Changes from 1.6 to 1.7: * Fixed comatibilty issues with Windows XP SP2. * Virtual COM port number assignment behavior has changed in v1.6: Device will be assigned the same virtual COM port the next time the device is plugged into the system or after a restart. Behavior in pervious versions was to assign a new port if the previous port used by the device is taken up by another scanner or some other resource in the PC. * Option to change port number using 'Advanced Setting' of 'Port Properties' in system 'Device Manager' is not supported, and hence disabled in this version. Changes from 1.5 to 1.6: * Virtual COM port was not removed if device is removed with an application opening a handle to the device in v1.5. This behavior has changed in v1.6. Now, the virtual COM port will be created when device is plugged in and removed when the device is detached, irrespective of its usage by applcation. * Virtual COM port will be created under HID Class instead of PORTS class. This does not affect the functionality of the device, and it will be visible as serial device from legacy applications. The device will be enumerated under HID devices instead of Port devices in Device Manager. Changes from 1.4 to 1.5: * Fixed issue in handling IOCTL_SERIAL_PURGE for RxQueue. ******************************************************************************* * 3.

USING THE SCANNER IN SIMPLE COM PORT EMULATION MODE OVER USB ******************************************************************************* 1. Plug in the device to USB port. 2. Scan the Simple COM Port Emulation bar code in USB Interface Section in Product Reference Guide. This needs to be done only once the deivce is connected to the PC. 3. A virtual com port will come up once the device is plugged in. This can be verified by the presence of a new Communication Virtual Port (COM port) in Windows Device Manager under HID devices. To view device manager, go to Control Panel -> System, in Hardware tab, click Device Manager button. 4. Use any application capable of communicating to COM port and connect to the emulated com port to interact with the scanner. 5. To stop using the device, close the application so that it releases the use of the emulated com port. Then unplug the device. Important: This mode supports one-way communication only i.e: transfer bar code data from the scanner to the PC host. ******************************************************************************* * 7. VERIFYING INSTALLATION OF THE SOFTWARE AND IDENTIFYING THE SOFTWARE VERSION NUMBER ******************************************************************************* The version of the drivers provided can be obtained by viewing device property in Device Manager. With the device plugged in, take device manager. To open device manager, go to control panel -> System, select Hardware tab, click Device Manager button. Expand Human Interface Devices node, right click Symbol COM port emulation device select Properties. In the properties window Click Drivers tab and click driver details button. File version number and provider details will be displayed. ******************************************************************************* * 8.
