IO_OUTP_CTRL 1-3

The outputs (Output mode, Polarity) are controlled via 3 advanced feature reg-

isters (see table 30).

The Polarity field determines whether the output is inverted or not. The output

mode can be viewed in the table below. The current status of the output can be

queried and set via the PinState.

It is possible to read back the status of an output pin regardless of the output

mode. This allows for example the host computer to determine if the camera is

busy by simply polling the BUSY output.

Note



Outputs in Direct Mode:

For correct functionality the Polarity should always be set

to 0 (SmartView: Trig/IO tab, Invert=No).
