How to enable NMEA output from C120W?

[alavarre]

Chuck good morning. Thank you. You are certainly prolific!

I've gone through this, details below.

• The AIS Layer Setup menu item cited in your second FAQ seems not to exist in my system.

• AIS 38400 is an option on Port 2, but not elsewhere.

• I am getting $APHDG and $APRSA sentences from the RS-232 connection to the Laptop (via a Gigaware USB-A to Serial adapter between the DB-9 RS232 connector and the laptop), but these are not listed in the setup sentences and the setup sentences do not appear.

• The second FAQ differs slightly from my MENU sequences, but my AIS Objects are set to ON:
Chart Application->PRESENTATION->CHART LAYERS->CHART LAYERS->AIS Objects, which are ON.

So it looks like it is time to call in a paid technician to sort it out. I was hoping that there was something simple that I was missing in the morass of information, but apparently there is not.

Thank you and RayMarine for all your time and effort helping others.

Best regards, Andy
=============== DETAILS =====================
>The NMEA 0183 ports of Raymarine MFD's are always ON.
Good, thanks.

>It is recommended that you initially verify that MFD's NMEA (0183) Output settings have been configured to transmit all listed NMEA 0183 sentences.

My system:
Menu→System Setup→System Integration→
NMEA Output Setup:Port 1→All sentences ON
NMEA Port Setting:Port 1→NMEA 4800 (the only other options are NavTex, that we do not have.)
NMEA Output Setup:Port 2→All sentences ON
NMEA Port Setting:Port 2→AIS 38400 (the other options are NMEA 4800 and NavTex.)
NMEA Output Setup:Port 3→is greyed out
NMEA Port Setting:Port 3→NMEA 4800 (There are no other choices)

This results in
Menu→System Setup→System Diagnostics→
External Interfaces→
SeaTalk→ Lots of send/receive
Seatalk HS (Ethernet)→ Link status UP, IP Address, etc.
NMEA Port 1 (NMEA 4800)→ Many transmitted, none received
NMEA Port 2 (AIS 38400)→ Many transmitted, none received
NMEA Port 3 (NMEA 4800)→ None transmitted, none received
SeaTalkNG→ Lots of send/receive

On the laptop (Linux) we do
stty -F /dev/ttyUSB0 4800
cat /dev/ttyUSB0
by either root or user in either simulation ON or OFF returns
$APHDG,93.8,,,,*6A
$APHDG,93.8,,,,*6A
$APRSA,-26.60,A,,*11
and a host of other similar entries. These seem to be the ouput of the Autopilot even though it is in standby?

stty -F /dev/ttyUSB0 38400
cat /dev/ttyUSB0
returns nothing.

>Typically the NMEA 0183 port which will be interfaced to anything other than an AIS receiver/transceiver will be configured to "NMEA 4800'.
That would be ports 1 or 3 above

>Typically, an AIS500 would have been interfaced to a C-Series Widescreen MFD via SeaTalkng communications protocol. Should the MFD have instead been interfaced to the MFD via NMEA 0183 communications protocol, then that port would need to be configured to "AIS 38400".
As noted, it “just worked” a couple of years ago and we haven't changed anything but the laptop. So presumably, the AIS information goes to the MFD and thence via RS-232/NMEA0183 to the laptop?
As described, the MFD reports all ports as very active, but the RS-232 line only shows $APGDG and $APRSA sentences.

>Finally, the AIS Objects configuration setting within the Chart application page/pane being viewed must be configured to ON.
And, therein lies the problem:
The manual says:
Enabling and disabling AIS silent mode
In the chart or radar application:
1.2.Press the MENU button.
Using the trackpad, highlight the AIS Layer Setup menu item,
then press the trackpad right to select it.

But in my system the AIS Layer Setup menu item does not exist.

Continuing:

>Please click here to view a FAQ addressing the NO AIS problem reported.
>- Verify that the Chart application page's/pane's AIS Layer (MENU->PRESENTATION->OVERLAYS->AIS) has been configured ON.
My unit does not expose that. We have
Chart Application->PRESENTATION->CHART LAYERS->CHART LAYERS->AIS Objects, which are ON.

Went through the FAQs, thanks, no joy.

So the bottom line is
In my system the AIS Layer Setup menu item seems not to exist.
