The Xanbus System

Network Components
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.
• 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.
Table 3-1 contains the arrangements of wire colors to pin numbers for the T568A
standard.
Important: See the specifications for each Xanbus device to determine how much power each
device consumes or supplies.
CAUTION: Equipment Damage
Do not use crossover cable.
