11.6.1 Input Polarity
Main Menu > System > Discrete I/O > Input Polarity
The iVu BCR 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.

11.6.2 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 BCR is a NPN device 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.
