NOTE: This setting affects both the Data Export Channel and Image Export Channel.
5.4.6 Discrete I/O
Main Menu > System > Discrete I/O
The Discrete I/O options are used to adjust iVu input and output settings.
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 sensor is Low To High, and for an NPN sensor it is High To Low. The user can change the
setting on the Input Polarity screen.
Input Pullup
Main Menu > System > Discrete I/O > Input Pullup
By default, the Input Pullup is disabled. If the device used to trigger and remote teach the iVu sensor is a Sinking device
(NPN) then you will only need to enable Input Pullup here if that device does not have its own pullup resistor. Otherwise,
this should be disabled.
Output Type
Main Menu > System > Discrete I/O > Output Type
Select NPN to configure the sensor's outputs to sink current. Select PNP to configure the sensor's output for source
current.
