GoMax Smart Vision Accelerator: User Manual

Using GoMax • 30

Configure the sensor as you normally would. For information on configuring a sensor, see the sensor’s user
manual.

Via an SDK Application

SDK applications can access accelerated sensors in the same way as with physical sensors, controlling
them and receiving messages. In SDK applications built using version 5.1 of the SDK or later, you only
need the serial number of an accelerated sensor to access it. In SDK applications built using SDK versions
before 5.1, you must specify the port used to access the sensor; for information on setting and viewing
the port settings in GoMax, see

Configuring Network Settings

For more information on accessing accelerated sensors via the SDK, see the SDK reference
documentation.

For general, introductory information on the SDK, see the sensor's user manual.
