3. Troubleshooting
3.1. Checking Device Status in the Device Manager
The Windows device manager can be used to check whether the Dta, DtPcie or Dtu driver runs
properly. To check the device status of a DTA or DTU adapter:
1. Open the Windows device manager: right-click My Computer, select Manage, and go to
Device Manager under System Tools.
2. Locate the DekTec adapter in the device category Professional audio/video interfaces.
3. Right-click DTA or DTU adapter, select Properties, and check the Device status pane.
The status should be: This device is working properly. If not, don’t try the Windows Troubleshooter
(it does not know anything about DekTec devices), but inspect the event log (§3.2) and the install log
(§3.3). If the computer does not boot, please review §3.4.
3.2. Checking the Event Log
The System Event Log can be consulted to check whether the Dta and/or Dtu device driver has been
loaded and started properly. To open the System Event Log:
1. Right-click My Computer, select Manage, and open Event Viewer under System Tools.
2. Select the System log.
3. Dta driver messages have Dta in the Source column;
DtPcie driver messages have DtPcie in the Source column;
Dtu driver messages have Dtu in the Source column.
If the driver loads successfully, the following event message is logged:
The Dta driver (Rev …) has loaded successfully.
Or The DtPcie driver (Rev …) has loaded successfully.
Or The Dtu driver (Rev …) has loaded successfully.
The device-driver version listed in this message should match the Dta/Dtu-version number listed in
the file overview in §1.2.
For each DekTec PCI card inserted in the system, a start-up message listing PCI-Card Type, Firmware
Version and Slot Number is logged, e.g.:
The DTA-145 (Firmware Version 3) in PCI Slot 3 has started successfully.
Obviously, if the Dta driver detects an error while trying to start the PCI-Card, the message above will
not occur. Instead, an error message is logged, which may be helpful to find the source of the problem.
For each USB device connected to the system, a start-up message similar to the PCI-card start-up
message will be logged.
3.3. Checking the Device-Driver Install Log
The device-driver install log is a text file (DtDrivInstall.log) written into C:\Program
Files\DekTec\Drivers (or a redirected path). In case of installation troubles, please contact DekTec
at support@dektec.com, attaching the install log.
