6.5 Device List Window

The device list window shows information on all devices currently connect to the NMEA 2000 network. The N2KAnalyzer software broadcasts a request to all nodes on the NMEA 2000 network, which in turn broadcast their identifying information. It then fills the device list window with information as it is received from the other devices on the network. This process repeats every ten seconds, and the device list window contents are updated accordingly.

The text for each device is normally displayed in black. Different colors are used to signify different characteristics of devices:

• Blue – identifies the gateway that is being used by the N2KAnalyzer software

• Red – identifies that a new revision of firmware is available for that device.

• Grey – device is not responding or has been removed from the network.

6.5.1 Node Address

Each device on an NMEA 2000 network claims a node address between the value of 0 (0x0 hexadecimal) and 251 (0xFB hexadecimal). These node addresses may change as new devices are added to the network. This column shows the node addresses claimed by each device on the network.

6.5.2 Manufacturer

This column shows the manufacturer reported by each device. The manufacturer’s names are read from a table in the N2KAnalyzer software which translates the manufacturer’s code reported by the device. If a new NMEA 2000 manufacturer has been added since the

N2KAnalyzer software was released, this will show up as a numeric value. If this happens, please either

• Update your N2KAnalyzer software by selecting Web->Download Firmware Updates menu item, or

• Check the NMEA website for the current list of manufacturer codes.
