Image Export Advanced
Main Menu > System > Communications > Image Export > Advanced
During the Data and Image export operation, the iVu output channels might become full. This can occur if the iVu is
producing export data (frames) faster than the data can be exported from the device or faster than the client is reading the
channel export data (due to bandwidth limitations).
The Advanced setting affects how the iVu behaves in this situation.
Select Hold READY to ensure that all frames are transmitted. In this case, the READY signal remains inactive (iVu is busy)
until the new frame has been added to the channel for transmission. Triggers might be missed during this time.
Select Do not hold READY to cause the iVu to discard the new frame if the channel is full and thus activate the READY
signal immediately after the current inspection is complete. In this case, the discarded frames are not transmitted.
Note: This setting affects both the Data Export Channel and Image Export Channel.
11.6 Discrete I/O Menu
Main Menu > System > Discrete I/O
Use the Discrete I/O menu to adjust iVu input and output settings.
11.6.1 Input Polarity
Main Menu > System > Discrete I/O > Input Polarity
The iVu has two input signals—Trigger and Remote Teach. Both of these signals are edge sensitive. The operation of these
signals is dependent on the Input Polarity setting.
•
Low-To-High—The Trigger and Remote Teach are detected on a low to high transition of the signal
•
High-To-Low—The Trigger and Remote Teach are detected on a high to low transition of the signal
The default setting for a PNP device is Low-To-High, and for an NPN device it is High-To-Low. Change the setting on the
Input Polarity screen.
