Symptom

Causes & Solutions

1. DigiView (Models DV3100 and DV3200) Power LED does not stay ON.

(A). The USB subsystem of the PC is turning DigiView Off due to a Bandwidth shortage.

REMEDY: Remove other USB devices that use a port on the same hub (internal or external).

(B). The USB subsystem of the PC is turning DigiView Off or DigiView is resetting due to insufficient power.

REMEDY: If you are using an external hub, change to a POWERED external hub or purchase one of better quality that meets USB specifications.

(C). The USB cable is not designed for High Bandwidth applications, causing communication errors.

REMEDY: Replace the USB cable with one designed for the High Speed mode of the USB port.

(D). The USB cable is connected to a case port that utilizes a low bandwidth cable internally, causing communication errors.

REMEDY: Connect DigiView to a port located directly on the Motherboard (rear port of the case).

2. DigiView is only identified as a SERIAL device by the USB subsystem.

(A). The USB sub-system is experiencing a problem with corrupted or missing files.

REMEDY: Look for a driver update to the USB hub (internal or external) or re-install its drivers. Refresh the DigiView drivers by re-installing the DigiView software.

(B). Operating System or computer needs rebooted.

REMEDY: Turn off the computer and re-boot the system.

(C). The USB cable is not designed for High Bandwidth applications, causing communication errors.

REMEDY: Replace the USB cable with one designed for the High Speed mode of the USB port.

(D). The USB cable is connected to a case port that utilizes a low bandwidth cable internally, causing communication errors.

REMEDY: Connect DigiView to a port located directly on the Motherboard (rear port of the case).

(E). The DigiView hardware has been damaged.

REMEDY: Call Technical Support for repair information.

3. One of DigiView's channels is connected to a transitioning signal, but the capture does not seem to show any activity or very little activity.

(A). The resolution of the Waveform View is too low to see the activity.

REMEDY: Zoom In to see the details of the activity.

(B). The signal has been defined with the wrong channel selected.

REMEDY: Edit the signal definition and change the channel selection. The colors are repeated for each group of 9 channels, so be sure to select the correct one.

(C). The signal definition has been "disabled".

REMEDY: Edit the signal definition and uncheck the Disabled option. The channels for disabled signals will not appear in the captured data.

(D). Bad Ground reference.

REMEDY: Connect one of DigiView's ground wires (black probes) to a ground point as electrically close as possible to the signal connections.

(E). Incorrect Trigger Threshold.

REMEDY:  The transitions will be undetectable If the trigger threshold is set too high or too low for the voltage range of the transitioning signal. Change the Threshold setting for the physical channel so that it is near the center of the signal's voltage swing.

(F). Insufficient power or Communication error, see 1.B,1.C,1.D above.
