I have a Raymarine RL70C with software version 4.11 connected to a Raymarine L760 with the chart slots, software version 4.11 also. Neither unit recognizes the other one is on the network. I have sent the L760 in for a sonar problem. Raymarine fixed that problem and tested the HSB2 communication. They said working properly. I have changed the cable and done the resistance tests on the pins. All look normal. Is there anything else I can try before sending the RL70C in for testing?
I would like to follow ... just a thought are Seatalks connected ? and HSB terminators ? I am sure one of the techs will address this soon
Welcome to the Raymarine Technical Forum Larry,
If these tests identify the problematic component, then it should be sent to Raymarine's Product Repair Center to be serviced. If all of these items are within the specifications listed above and fault isolation fails to identify the problematic component, send each of the hsb² components and as much of cabling as can easily be removed to Raymarine's Product Repair Center to be tested as a system.
