Network Components

975-0239-01-01
A Xanbus network consists of the following components:
• Xanbus-enabled devices—these include the XW System Control Panel, the XW
Inverter/Charger, XW Automatic Generator Start, and XW Charge Controller. The
maximum number of Xanbus devices connected to a single Xanbus network should
not exceed eight devices.
• Xanbus power supply—the network must have at least one device with a power
supply to run the network. The total network current supplied by all the
power-sourcing devices must be greater than or equal to the total current drawn by the
power consuming devices. The power supply must be capable of providing 15 Vdc/
200 mA to each device. The XW Inverter/Charger can provide sufficient network
power.
For example, in a system with an inverter/charger, a XW System Control Panel and an
Automatic Generator Start, the inverter/charger is a power-sourcing device capable of
providing 800 mA at 15 Vdc while the two other devices each consume a maximum
of 200 mA for a total maximum consumption of 400 mA. In this example, the
network is properly configured from a power perspective because the power source is
capable of providing more current than is needed: 800 mA > 400 mA.
Important:
See the specifications for each Xanbus device to determine how much power each
device consumes or supplies.
• Xanbus cables—each Xanbus-enabled device is connected by a Category 5 (CAT 5 or
CAT 5e) cable, a standard cable available from Xantrex or any computer supply store.
The cable consists of eight conductors in four twisted pairs with an RJ45 modular
connector wired to the T568A standard.
CAUTION: Equipment Damage
Do not use crossover cable.

Figure 3-2 Xanbus Cable, RJ45 Connector Pin Numbers and Network Terminators

• Network terminators — the Xanbus network must be properly terminated at each to
ensure the communication signal quality on the network. If the network is not
properly terminated, signal quality is degraded and performance on the network is
reduced. Permanent configuration without terminators is not supported by Xantrex.
The XW Series and other Xanbus-enabled devices ship with one terminator already
installed. Depending on your network layout, this terminator may need to be removed
and inserted into another device elsewhere in the network.
