Hello.
Looking for advice regarding issue with Cerbo MK2 and connection to NMEA2000.
Issue is as follows:
Cerbo will not resume sending data to the NMEA2000-network after it has been powered down and then powered back on again.
When the network is powered on again, the Cerbo will see other devices on the network, but other devices will not see the Cerbo.
After the network powers up the Cerbo does recognize that the network is available, as the network-status on the VE.can port changes from “passive” to “active”.
It will also receive RX packets.
If the Can profile “VE.Can & Can-bus BMS” is selected it will even start counting up TX-packets, meaning it sends something out on the network, but it is not recognized by other devices.
Only way to get it going again is to go into the CAN-bus profile for the specific port and toggle between protocols, that seems to restart the data transmission to N2K-network correctly.
What I have tried without success:
-Checked connections
-Placing terminator in second VE.Can 1 port.
-Changing between and “VE.Can & Lynx Ion BMS” and “VE.Can & Can-bus BMS” profile (each will work until network is powered down).
-Checking that NMEA2000-out is selected and no conflicts i ID device-numbers.
Anyone else had this issue and know of a fix?
Keeping the N2k network on at all times is of course not an option.
It will be powered down after each time using the boat.
It’s a little odd that the Cerbo will see other devices just fine as they come online on the N2K network but not transmit data again.
