Hi there. I have two furuno ecdis onboard. Frw days ago ive noticed the loss of sync between ecdis units. it wit went away but come back. now it looks like it doesnt sync at all. ive tried urge sync, restarting units etc. on one ecdis the lights on LAN port are blinking on and off, in few seconds interval. on other they blink continousely. also ecdis cant print by local network printer. this all looks like some sort of sudden network conflict. do you know how to solve this issue? when i try to sync it says "cannot connect to peer" ip number".
