Adding a 2nd A78 mfd with wifi

Welcome to the Raymarine Forum iplat,

Unfortunately, it is not possible to do as you have suggested. At the time of this response, the two MFDs would need to be interfaced to one another via a cabled Ethernet connection. Unfortunately, there would be little choice but to remove the plug from one end of a RayNet (F) to RayNet (F) Cable should you be unable to chase the cable's plugs through the tubing. You may want to consider obtaining a RayNet (F) to RayNet (F) Cable which is slightly longer than necessary to span the cable chasing distance between the two MFDs. One of the cable's plugs may then be cut off to permit the cable to be chased ... although not recommended unless absolutely necessary, it is not uncommon for this to occur. After chasing the cable, a shielded RJ45 plug may then be installed onto end of the cable from which the plug had been removed. An A80247 RayNet (F) to RJ45 (F) Adapter would then be used to complete the interface between the two MFDs. For equipment which will be installed by the owner, the only product for which warranty would potentially be impacted would be the cable itself ... as the cable is only responsible for carrying signal, not power. In a nutshell, should any communications issues arise following the installation, the problem would be fault isolated by testing the MFDs using an unmodified cable to perform a temporary connection between the products. The products function correctly using the unmodified cable, then the fault would be isolated to the modified cable and Raymarine would not be responsible for replacing the modified cable.
