6.11.2
CONNECTING ONE OR MORE NTL720s TO A COMPUTER USING A UX8800
Use the UX8800’s front panel Ethernet port and the supplied Ethernet crossover cable to connect directly to a
computer’s 10, 10/100, or 100 Mbps Ethernet port. A user-supplied, shorter or longer cable may be
substituted. The UX8800’s Ethernet port is auto-negotiating, meaning it will automatically exchange
information over a link about speed and duplex capabilities and negotiate these to the highest common
denominator.
CAUTION:
An Ethernet crossover cable is required when connecting two Ethernet ports in the
same layer of the OSI model (Open Systems Interconnection Reference Model). A computer’s
Ethernet port, meaning its NIC (network interface card), and the UX8800 are both OSI layer 3
ports. Therefore, an Ethernet crossover cable is REQUIRED when directly connecting the
UX8800 to a computer’s NIC. An Ethernet crossover cable reverses transmit and receive pin
connections between the connectors at each end of the cable.
Connect one of the U-Net ports on the UX8800’s rear panel to a U-Net port on the NTL720. If there are
more than one NTL720, connect the other U-Net port on the NTL720 to the next NTL720, and so on.
This configuration is used to route any number of UX8800 outputs to the NTL720s on the U-Net chain.
Again, EAWPilot is used for U-Net configuration.
It is recommended that you connect the last free U-Net port to the first NTL720. A ring is created
so the audio and control signals have two paths around the network, and the integrity of the
network is maintained in the event that one NTL720 should go offline.
There is no requirement to connect Port 1 to Port 2 or vice versa. Signals are sent out both U-Net
ports bidirectionally so any port can be connected to any other port. It is recommended, however,
that the NTL720s be connected sequentially, top down or bottom up in an array.
