NXDT104 EXPANSION BOARD, DANTE™ PATCHING AND REMOTE CONTROL
implementation of Ethersound™ networks.
Dante™ networks can be compared to a standard computer network. Dante™ is based on
TCP/IP so a very large choice of devices can deal with Dante™ information just like
standard network packets.
Bellow is a few advices for correct Dante™ network implementation.
Hubs
A hub (also known as repeater) is a central connection point for computers on a star-
topology-based network.
WARNING! Due to their internal architecture, repeater hubs MUST NOT be used in
Dante™ networks.
Switches
Dante™ is supported on 100 Mb or 1000 Mb Ethernet networks. Be sure to use only
switches compatible with these network speeds.
WARNING! Some Dante™ compatible devices support only one of the two above
speed. To connect a 100 Mb only Dante™ device with a 1 Gb only Dante™ device you
cannot use a direct cable, but you can run through a 100 Mb/1 Gb switch.
Wireless LAN
A local area network that transmits over the air typically (but not exclusively) in an
unlicensed frequency or, among others, infrared line of sight. Wireless access points (base
stations) are connected to an Ethernet hub or server and transmit a radio frequency that
can penetrate walls and other non-metal barriers. Roaming users can be handed off from
one access point to another like, for example, in a cellular phone system. Wireless LANs
are not suitable for Dante™ networks due to significant bandwidth limitations and
unpredictable latency.
Ethernet cables and fiber optic
Cables used within the Dante™ network are straight cables. See previous description in
NXES104 paragraph about different cables type and fiber optic recommendations (same for
both network technologies).
Installation inside the NXAMP
To install the NXES104 card inside an NXAMP Powered TDcontroller, first remove the two
screws on each side of the NX-DLFT card on the rear of the amplifier. Keep these screws as
