IO_OUTP_CTRL 1-2

The outputs (Output mode, Polarity) are controlled via two advanced feature

registers (see Table 24: Advanced register: Output control on page 58).

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.

From firmware 2.03 onwards it is possible to read back the status of an out-

put pin regardless of the output mode. This allows for example the host com-

puter 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).
