3.2 Standard Data Interface to the CDU
The MX575 is IMO type-approved to provide the primary DGPS positioning
information used for navigation as well as True heading and Rate of Turn (ROT)
when used as the primary antenna unit to the MX CDU. This is the standard
system connection for the MX575 and MX CDU. This is achieved by connecting it
to the antenna port (PORT 3) of the MX CDU. The MX CDU will automatically
configure the MX575 to output the NMEA data at 19200 baud rate, turn on RAIM
feature and heading output to 10 Hz.
Please refer to the following figures 27, 28, 29, 30 31 and for the standard wiring
interface to various MX CDU models.
