For all data items, one of the following codes will be displayed:
– – – No data or no NMEA sentence containing the data
needed is available at the input port.
OK Valid data found
INV Message with invalid information.
FRM Message has format failure such as
– – – No data or no NMEA sentence containing the data
needed is available at the input port.
OK Valid data found
INV Message with invalid information.
FRM Message has format failure such as
a) Incorrect check sum
b) Wrong contents in datafield(s)
b) Wrong contents in datafield(s)
If data are missing or invalid, perform the following:
• Check the NMEA signal monitor (see below)
• Open the source select page in the User Setup2 menu and
• Check the NMEA signal monitor (see below)
• Open the source select page in the User Setup2 menu and
check that data are available
• Check the navigator setup and make sure it is transmitting
appropriate data.
• Perform a NMEA Port Test (hardware) as per below.
Note !
The “WIND” reading is the apparent wind from port (L) or
starboard (R). The “SPEED” reading is the speed through
water.

NMEA Port test (AC hardware)
Disconnect the cables on the Main PCB in the Autopilot
Computer and connect TX1+ to RX1+ and TX1- to RX1-.
Similarly, on the Power PCB connect the NMEA ports the same
way; TX2+ to RX2+ and TX2– to RX2–.
