We have a NMEA cable connected to the master RL70C that is a
work-around for getting NMEA output for the following devices (this is
necessary, as we understand it, because the RayTech Navigator program on the laptop causes the
E85001 to convert data to SeaTalk for the RS232 serial output).

History
During new vessel delivery sea trials it was determined that the
RL70C plotters were displaying information erratically. The vessel icon
would travel along the course line skewed or backwards, the chart
display and radar displays were mirrored from each other showing the
land to be to port on the chart while the radar overlay depicted it to
starboard. The system could be synchronized so it displayed properly
only to have it revert to it's initial behavior when re-powered. After
hours of cell phone discussions with RayMarine (RM) techs a local
service provider attempted to download a program upgrade into the course
computer resulting in the computer freezing and being sent back to
RayMarine. Their supposition was that the computer software was having
problems with the presence of the slaved RL70C. When the system was
re-installed it exhibited the same behavior as before.
We finally reached a RM tech that advised us
to go through the initialization sequence using the Autopilot (not the
RL70C menus) and then remove the yellow SeaTalk connection from the
Rate-Of-Turn gyro (GyroPlus2). We did that and the heading and radar
overlay problems disappeared. The ROT gyro status LED blinks red all the time so we don't know if its functioning or not. At
any rate the system displays the proper information and the auto-pilot
functions as expected. Our system is wired per Owners Handbook, Doc
#81198-1, Feb. 2002, page 28, lower schematic with the exceptions that
NMEA out appears to be connected to the slave RL70C and the yellow
SeaTalk wire from the GyroPlus2 is not connected at the T400 Course
Computer. The rate output is wired per page 29. Older
manuals show the fluxgate wired through the GyroPlus2 with a SeaTalk
feed to the Course Computer and NMEA to a RL70C (Type 150/400 Autopilot
System installation Guide, Doc. # 81173-3, June 2001, page 21).
The system has an on-going issue in that the master RL70C shuts
down and reboots periodically disconnecting the radar scanner and
freezing the slave RL70C. After reboot the slave functions though radar
has to be restarted. This happens frequently when entering a harbor or
constricted waterway while one is trying to zoom in on the chart. I
suspect it has something to do with the way the charts quilt but cannot
confirm this. At any rate it has added to my gray hairs many times. RayMarine says it's a C-Map issue and of course C-Map says it's
a RayMarine issue. I put the problem on RM - I bought their product. I can help
lessen the frequency of crashes by making sure I have only one C-Map
chart chip in the master RL70C (diminished functionality).
Late May 2007 lightning struck near the vessel while it was in
it's cradle on the hard. We discovered on launching that the knot meter
didn't work. BoatUS had a surveyor haul the boat and thoroughly inspect
it - confirming that there was no direct hit and that EMI had apparently
damaged some of the instruments ability to communicate via SeaTalk. One by one the
cockpit
instruments were replaced until the system worked and all the user menus
were functional. By the time we had everything working and communicating
properly we had replaced all of the cockpit instruments (with the
exception of the slave RL70C), the knot meter transducer, and the VHF as
the remote microphone circuit no longer functioned properly. After the
instrument replacements the system worked as it had prior to the damage.
It still crashes when there are multiple charts for a given area and
occasionally when ranging up and down.
In January 2007, while installing SkyMate, we were unable to get a
usable Lat/Lon output from the E85001 interface. We replaced the E85001 with no
success. SkyMate operation via the laptop (e-mail, FAX, position
reporting) is communicated using a USB port but the SkyMate's CPU should
be getting it's Lat/Lon via NMEA from our RayStar 125 GPS (if no GPS
signal SkyMate uses a less accurate doppler satellite calculation). We had a
SeaMark tech onboard
2/7/07 to troubleshoot the problems and design a work-around so
our VHF received lat/lon from the master RL70C, leaving the E85001
dedicated for serial communication by the RayTech Navigator program via
a SeaTalk conversion. This leaves our Nobeltech software and SkyMate
without a GPS input.
Partial Recent System Log
02/24 /07 -
When we left to cross the Gulf Stream we had the radar scanner on.
Every time I tried to range in or out the master RL70C crashed and
rebooted, shutting down the radar scanner and loosing the route data.
(The slave shows no map data available until the master reboots. The
master reboots, waiting for a "continue" to acknowledge the RM
disclaimer.) I tried the radar without overlaying it on the chart. Again whenever I
tried to change range the master rebooted. Usually when we are using
radar we are entering harbors or approaching unfamiliar shores.
We try to range down the master before we come into these area
thinking that the slave may be asking for detail that the master
hasn't accessed. It seemed to help a little. As I think back to earlier crashes some seemed to occur at random...
however sometimes the system ranges up by itself (a little trick it
does when you leave it on a low range, 1-6 nm, for an period of time). The crashes may have
occurred during one of those system range changes - we may have only
noticed the crash and reboot. I don't believe the scanner was on
(other than standby) every time the system rebooted (it is always on
standby). This happens enough that we've coin the term "Raymarine
Moment" for the events. The radar scanner had been repaired by Raymarine in December '05
after shorting due to water intrusion... though the problem existed
before that time. RL70C power supply
issue?
3/9/07 -
We've had several cases of the master rebooting
while in the Bahamas - with the radar in standby or off. The most recent was
today when it rebooted 3 times while we were entering the narrow
channel into Norman Cay with range set at 1nm (there is a chart
overlap in this area). It sure makes life
interesting... being in a tight spot and having a Raymarine Moment.
We've even had it reboot at night when the slave RL70C was off
and the master was on anchor watch. Naturally it defaulted to anchor
watch off when it rebooted. It's almost worse than no system as you
can't trust it.
3/23/07 - Squalls
forced us to use the radar for the first time since we crossed the
gulf stream. We've avoided it to try to minimize the number of crashes
- turning the scanner off each time we initiate the system. Every time
we changed range the system crashed with either or both the slave and
master rebooting. Causing us to wait while the radar powered to
standby so we could restart the scanner. It didn't seem to matter
whether we had the radar screen or radar overlay on the chart.
It seems like every time the processor has to deal with
a heavy load something reboots? Very frustrating!
We've elected to quit using the radar, but
still have occasional crashes. Additionally the chart changes ranges on
it's own - typically up to 12, 24 or 48 miles from 1 - 6 nm, something it has always
done. We've tried making sure the master is at the range we want
thinking it may be conflicting with our ranging on the slave, but
that doesn't really seem to solve the problem.
5/1/07 - Today
the system powered up with the autopilot reading 180 degrees off our
heading, hence the two RL70C displays show the boat backing down the
course line. Haven't had this issue since the original system was
installed and troubleshot. User calibration only provided 2 choices -
indicating the pilot doesn't know its on a sailboat. Tried to get into
dealer calibration, get a CRL display, no access. Got to get RM on the
line again as the manuals don't address this. Checked the radar overlay
and it is showing land off the port side of the boat which is correct
orientation to the bow but 180 degrees to reality. Last time this
happened we had to do 2 circles to linearize the system with the yellow
SeaTalk wire connected from the Course Computer to the ROT gyro, then
disconnect the yellow SeaTalk wire from the ROT gyro and make final
heading corrections to the Autopilot via the dealer menu at the 6002+
Pilot.
5/2/07 - Contacted Raymarine and got
assistance in accessing the Dealer Menu (hold standby until Cal
displays, then press Auto once, displays lock OFF, use display to access
features), made the heading correction.
Next step, re-initialize with the yellow SeaTalk wire on, then remove it.
5/10/07 -
While traveling in dense fog using radar we had a brief "Raymarine
Moment" when our radar and chart plotter crashed as we crossed the
interface between two electronic charts. I had 2 chips in the master as
we were leaving one C-Map and entering another. I removed the chip for Norfolk
to Jacksonville, leaving the Chesapeake chip in place and rebooted the
system.
6/24/07 - Entering the
traffic in New York Harbor the system rebooted twice (radar was off). I
had 2 chips in as this was an area where we changed chips. Removing one
settled the system down.
8/07 - Our wind
instrument is acting funky... sometimes it is reading correctly and
sometimes 30-40 degrees off. If I calibrate a correction on one tack I
get double the error on the other. In that the ST60 head was new 1 year
ago I suspect the masthead sender. I took it down, inspected, cleaned,
straightened the warped vane and reinstalled it. Didn't make any
difference. Some days it works perfectly, most of the time we can't
trust it.
Ruth had a "Raymarine Moment" the other day.
While sailing in autopilot auto mode she moved away from the helm to
adjust a sail. The system elected to chose that moment to dump to
standby causing the boat to violently turn into the wind. Don't
know why but it happens every so often, 4-5 times a year.
11/3/07 - We continue
to have operating surprises. Last week the autopilot went to standby
(helmsperson caught the wheel in time), later is lost the route data a
couple of times. This week it elected to quit reading the C-Map chip -
switching to 1200 nautical mile range. We got the chart back by
switching the C-Map to the other socket. Makes life interesting.
11/07 - One of the
system's little frustrations is the trick of jumping ranges by itself.
We may have the system set at a 1.5 mile range while negotiating a
narrow inlet only to look down a find the chart has reset to 24 miles.
This leads to panicky process of scrolling down thru 12, 6, and 3 mile
ranges to get back to 1.5. I guess this is a feature designed to make
one remember the larger picture. At 6 knots that's hardly a concern.
1/30/08 - Generally
the system works. Other than an occasional auto-helm dump we can depend
on the depth, speed, log and GPS. The chart plotter continues to have
"Raymarine Moments", jumping up 2 or 3 ranges while you are entering a
narrow channel or just plan rebooting at the cost of routes or waypoint
planning. This past week it's been cranky again. It's still a big step
above doing it all with a hand bearing compass and grease pencils
(though we keep them handy... just because).
5/25/08 - Haven't
logged any notes lately, not because it's gotten better, I've just
gotten use to the crashes and the charts changing scale on their own.
You have to pay attention to details like system date when looking at
tide charts, today it was 5 years off. Who knows why, yesterday it was
correct. Ariel's new system has it own little quirks. Hey, it beats a
hand bearing compass and a sextant.
