We have been experiencing issues where our Simrad radar
won't turn on from in Open CPN
. There are similar issues on the forum and we have tried all these fixes without success, hoping someone here can provide some assistance.
is recognised by OpenCPN
, but wont turn on, and is stuck on Waking Up setting. OpenCPN
log contains the following clause repeated 5 times every second (refer attached)
Radar busy encountered, overlay_refreshes_queued=1
Notes about config:
3G Radar via R10
Raymaraine evolution EV1 heading sensor with NMEA2000 SIMnet
Running on Lenovo laptop
with no Ethernet port. Radar in via a USB/Ethernet converter (flashing solid blue with flashing red/green lights)
Red/Yellow power connected together with a 5A fuse
comes into laptop
via USB port
Worked fine for first 2 months
Intermittent issues with IP conflict started to arise. Radar would work
after uninstalling and reinstalling software
or intermittently for no apparent reason
IP conflict fixed by manually assigning IPv4 address, error fixed and radar worked 3 consecutive times but has since stopped turning on.
When the radar manages to switch on the quality and overlay is good, aligns with charts
and visual reference points.
Debugging so far
Update Opencpn from version 4.6.1 to 4.8.0 and BR24pi from 2.1 to 3.817
into radar R10 device from boat
, sitting at 200mA then jumping up to 800mA intermittently.
Measured voltage from R10 device out to Radar.
o Red 13.8V (alternator output)
o Yellow 12.2V
Uninstall / reinstall software
Install OpenCPN and BR24pi onto Microsoft Surface Pro, same issue
to remove potential conflict
Removed heading from R10 device to avoid conflict
Updated ini files and set Verbosity to 3, log attached. (Extract of previous logs
where radar was working also attached).
Updated Ethernet/USB converter firmware
When Radar disconnected Emulator mode works fine
