Port 1 is set to “AN” or “MAN”. DIP-switches SW7 and SW8 are ignored when Port 1 is
set to “AN”. The following table details possible Link Mode DIP-switch configurations.

NOTE: Connecting two converters set to any of the RFD modes is illegal and will
cause a “deadly embrace” lockup.
NOTE: It is recommended to keep the LS setting (default) until initial configura-
tion is complete.
