Ordering Network Components
Table 3-2 provides a partial list of network components and part numbers. Ready-made
cables are available in standard lengths from 3 feet to 75 feet.

Network Layouts
Xanbus-enabled devices can be connected in one of two Xanbus network layouts:
multi-drop backbone or daisy chain. Each network layout has advantages and
disadvantages, depending on the application and/or environment. It is up to the installer or
system designer to decide which layout is best for the installation.
Multi-Drop Backbone Layout
In a multi-drop backbone layout, each Xanbus-enabled device on the network is connected
by a drop cable to the network bus or backbone with a network connector, as shown in
Figure 3-5.
Terminators are required at both ends of the multi-drop backbone cable, as shown in
Figure 3-5. 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, 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 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 the cost of the network
connectors (a daisy chain layout uses no network connectors). Each device in this layout
requires its own network connector.
