8. After completing network cabling, tighten all cable clamps (ensuring there is
adequate slack in the cable) and replace the communication ports covers on
all units. See Figure 3-12.
Verifying the Xanbus Network
For long Xanbus networks (greater than 100 m), you must verify network
integrity using a CANbus network analysis tool such as the Maretron N2KMeter
Diagnostic Tool for NMEA 2000 compatible networks. To determine if the
network is healthy, check to see if any bus errors are present on the network. The
presence of bus errors, specifically more than one bus error per second, indicates
that the network is not operating optimally.
•
If the CANbus analyzer indicates your network is not operating properly,
check the following and then re-test the network.
•
Make sure the total Xanbus network length has not been exceeded. See
Table 3-2, “Total Xanbus Network Length” on page 3–11.
•
Make sure the network has only two terminators installed – one at each far
end of the network.
•
Make sure there are no long stub connections coming from a Xanbus 3-port T
connector (if any are used). Daisy chain network configuration is the optimal
configuration.
•
Make sure all cable sections are correct and not shorted anywhere.
CAUTION
For the inverter to meet regulatory requirements, the communication ports cover must be
installed.
