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.

Important: Do not mix the two types of network layouts. Mixed configurations are not supported by Xantrex.

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.
