Terminators Terminators are required at both ends of the multi-drop backbone cable,
as shown in Figure 2. Therefore, the Xanbus-enabled devices do not
require their own termination. With only one terminator, the signal quality
is degraded and performance on the network is reduced. Permanent
configuration with only one terminator is not supported by Xantrex.
If cables are placed at the end of the network (as in Figure 2), female
terminators are required. Otherwise, male terminators can be inserted
directly into the open jack of each network connector at the end of the
network.
Advantages The multi-drop backbone layout is reliable and robust and is
recommended for OEM installations.
In this layout, Xanbus-enabled devices can be removed or replaced while
still keeping the network operating.
Disadvantage The main disadvantage of this layout is cost. The network connectors are
more expensive than in a daisy chain layout (which uses no network
connectors), and each device in this layout requires its own network
connector.
Daisy Chain Layout
In a daisy chain layout, each device on the network is linked with separate
lengths of cable, as shown in Figure 3. This layout does not require
network connectors.
Terminators As in the multi-drop backbone layout, two terminators are required to
ensure the communication signal quality on the network. The Xanbus-
enabled devices at each end of the chain must have a male terminator
inserted into their open network ports, as shown in Figure 3.
Advantage The advantage of this layout is that it is less expensive to install because
network connectors are not required.
