jsaronson,

Your description of the backbone installation appears to be correct. Should there be more than one MFD within the system, then the MFD which has been connected as a spur to the SeaTalkng backbone must be configured as the system's Data Master MFD (HOME->SET-UP->MAINTENANCE->MAINTENANCE->DATA MASTER). Should this be so, then it is recommended that the backbone's components be inspected for signs of damage, splices, etc. Excess SeaTalkng Cable should be loosely coiled (3" minimum bend radius) and secured to a bulkhead. Subjecting a communications cable to a bend radius which is less than this may cause permanent damage to the cable. Should no cable problems be identified, then it is recommended that MFD's spur be tested by temporarily disconnecting the p70 from its spur and then reconnecting it to the Spur Cable which had been interfaced to to the MFD. Should the p70 Autopilot Control Head then be able to detect and interface with the autopilot, then it would appear that the MFD has suffered a failure of its SeaTalkng communication circuitry, necessitating that it be bench tested/serviced by Raymarine’s Product Repair Center.
