If the Configuration Utility fails to detect the target, the NO DEVICES
FOUND message box displays (see Figure 30).
Note:
Normally a target should be present in one of the first 16 ports.
Occasionally, however, particularly if you are connected through a USB
Hub, Windows will assign a virtual COM Port number higher than 32.
Click
YES
to continue searching for target(s) on higher port numbers.
Click
NO
if you are sure that the target is connected to a port number
within the range of the port numbers shown in the message box (see
Troubleshooting
If you are sure that the target is connected to a port number within the range of the port numbers
displayed in Figure 30, check the following:
•
Is the USB driver installed? If not, refer to the section titled
Pre-installing the Common USB Port
Driver (A-1519/1520 and A-910)
SiLabs CP210x USB to UART Bridge Controller on Page 12.
•
Ensure that the target USB cable connectors are fully inserted into the computer and target.
•
Ensure that the target is ON. The center LEDs (see Figure 1, Front View 2-1) should be lit
continuously if the target is in Application Mode or blinking once every three seconds if the target is
in Configuration Mode.
•
Ensure that the laser is ON and scanning across the position sensor (see Figure 1, Front View 2-4).
•
Click the
SCAN PORTS
button to rescan the ports (see Figure 25).
