[CA] [CA11] E120/E80/RD424/DSM300 won't talk to each other

Welcome to the Raymarine Forum Bill,

Q. The Raymarine Forum FAQs say that if the 2 MFDs won't see each other, to change the Network Switch. I did that, no change.
A. There's actually more to it than that. Please click here to view a FAQ addressing this subject. Disregard the suggestion to verify/update the DSM's software. From the information specified therein, what IP addresses and serial number were reported within the MFD's diagnostics for each MFD?

The following method may be used to test each MFD's Ethernet communications interface:

Testing MFD Ethernet Port:
- configure a PC Ethernet adapter's Internet Protocol Version 4 (TCP/IPv4) settings with the static IP Address 10.0.0.7 and subnet mask 255.0.0.0
- connect the PC's Ethernet port to one of the SeaTalkhs port of one of the system's MFDs via an Ethernet patch cable and a SeaTalkhs cable that have been joined with a SeaTalkhs Crossover Coupler, SeaTalkhs Network Switch, or SR6 Sirius Satellite Weather Receiver/Network Switch.
- Open a windows Command Tool and ping the MFD's IP address as determined above (ex. ping 10.0.03). Should the command result in responses from the MFD respond, then its Ethernet communications circuitry would be deemed to be operational.
