Symptom

Data cannot be transferred normally.

Cannot be connected normally.

When images are successively downloaded, it is the same image that appears on PC.

Warnings are displayed on the PC.

The DS-L1 will behave as follows after being connected to a PC.

•Although a CF card is inserted into position, a “Please insert media” message is displayed if you click the icon for the media drive.

•A similar message is displayed if you click the icon for the CCD image drive.

•Other USB devices already connected to the PC are disabled.

Corrective action

•Make sure the USB 1.1 interface board and USB 1.1 hub used in the system are compliant with USB 1.1 standards, and that the USB 2.0 interface board and USB 2.0 hub used in the system are compliant with USB 2.0 standards.

•Check that only one hub stage exists between the interface board and the DS-L1. Use of only one hub stage is recommended.

•Make sure the USB cables used in the system are USB-compliant. When the DS-L1 is connected via USB 1.1, use USB 1.1 or USB 2.0-compliant cables. When the DS-L1 is connected via USB 2.0, use USB 2.0-compliant cables.

•Check that the OS version used is compatible with the system. Mac OS is not supported.

Supported OSs

Windows 2000 Service Pack 3 (SP3) or later Windows XP

•Make sure the USB host driver made by Microsoft Corporation is installed. The driver included with the USB board does not work properly.

•Images are updated once every 5 seconds.

Be aware that if files are loaded into a PC at intervals shorter than 5 seconds, the captured image may not always be the latest one.

•A warning in the task tray (system tray) such as “HIGHT-SPEED USB Device Plugged into non-HI-SPEED USB hub” is displayed when you connect to a USB1.1-compliant USB port. This is not an error, and the DS-L1 operates as a USB 1.1 device.

•There may be a conflict between the drive letter assigned to the DS-L1 and that of another USB device already connected to the PC. Change the drive letter for the DS-L1, referring to “5.3.2 Outline of the Disc Drive” in Chapter VI.
