IO_OUTP_CTRL 1-4
The outputs (Output mode, Polarity) are controlled via 4 advanced feature
registers (see
Table 28: Advanced register: Output control on page 103).
The Polarity field determines whether the output is inverted or not. The out-
put 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).
Register Name Field Bit Description
