Y NOT RECOMMENDED for mobile installations At the moment no EtherSound equipment is fitted with optical sockets Hence using optical fibres involves media converters copper to optical and optical to copper Many switches have optical ports thus it is possible to use optical fibres to interconnect switches but this only applies to fixed installations since these switches require ordinary fibres Connectors For mobile use NEXO strongly recommend the use of Neutrik ETHERCON connectors Ether ETHERCON RECOMMENDED They give good contact between the Sound metal case of the equipment and the cable shielding Above all they ensure a robust connection equal to that of XLRs RJ45 NOT RECOMMENDED They are very fragile the plug is only held in the socket by a tiny plastic flap Contact between the metal case and the cable sheathing is insecure However they remain the only solution if advanced switches are used For fixed installations RJ45 cables may be used if not subjected to handling NXTENSION USER MANUAL DOCUMENT REVISION 011004 PAGE 13 Unshielded RJ45 PROHIBITED The NX242 is an item of equipment with certified electromagnetic performance The use of an unshielded connector will th invalidate the certification and expose the user to problems arising from electromagnetic interference or emission s g oun 2 72 Interconnection components Analogue techniques Certain practices common to analogue working a
