9.1.3.2 Data Ports
The Data Ports page allows you to specify which data packets or messages are output on a periodic basis and
at what rate via a range of serial and Ethernet ports.
Note: The GPIOs and auxiliary port are configured in the Data Ports page only if they are being used as
serial transmit and receive lines. To configure GPIOs as digital or frequency inputs or outputs, use the
9.1.3.5 GPIO page.
The default ANPP format packets enabled for the primary port are the 11.4.1 System State Packet (ID #20)
and the 11.4.9 Raw Sensors Packet (ID #28) at 20 Hz and these typically provide all the data that a user will
require. Other ANPP format state packets can be enabled as required.
