Online Tree Elements

The main elements of the Online Tree are described below:

System

The highest-level element in the Online Tree is the System element. This element indicates the number of devices in the system, followed by the Master Controller’s IP address (FIG. 235).

FIG. 235 Online Tree - System element

Master (NetLinx and Enova DGX/DVX)

The elements following the System in the online tree represent the Master Controller (FIG. 236). Click the "+" icon to expand these folders to view the sub-devices contained.

• • NetLinx masters contain two sub-devices: an NI Master Controller (port 0), and a Device Controller (port 5001).
  • Enova DVX (All-In-One Presentation Switchers) and DGX (Digital Media Switchers) contain three sub-devices: the NI Master Controller (port 0), the Device Controller (port 5001) and A/V Switcher/Scaler (port 5002).

NetLinx Master (NI-3200 shown). NI Controller (port 0 - 00000)

Device Controller (port 5001 - 05001)

Enova DVX or DGX (DVX-3150HD-T shown). NI Controller (port 0 - 00000)

Device Controller (port 5001 - 05001)

A/V Switcher (port 5002 - 05002)

FIG. 236 Online Tree - Master Controller device elements (NetLinx Masters and Enova DVX/DGX)

These are the specific device components within the Master; each of which requires it’s own firmware. For example, NetLinx Controllers use two firmware files: "Master Firmware" is used by the NI Controller and "Device Firmware" is used by the Device Controller. Enova DVX All-In-One Presentation Switchers also utilize "Switcher Firmware" for the A/V Switcher component.

Click on each of the Master’s component folders to view the Sub-devices and Ports contained in each (FIG. 237).

Devices

The elements below the Master Controller in the Online Tree represent devices in the system. These elements indicate the device number, device name and the device firmware version currently loaded (FIG. 238).

FIG. 238 Online Tree - Device element

• • Click the plus sign to expand the view to show sub-devices and ports on the selected device.
  • Sub-devices are indicated with red icons, and give a description and firmware version info (in parenthesis) for each.
  • Below the sub-devices is a listing of Ports on the device. To check the status on any port, right-click on a port and select Check Port Status from the context menu. The results of this status check are indicated in the Status tab of the Output Bar (FIG. 242).

NOTE: NX-series controllers may list up to 22 ports depending on the model number of the controller. Not all listed port numbers are valid. See the NX-Series Controllers Hardware Reference Guide for a list of valid port numbers for each controller model.

Virtual/Dynamic Devices

The entry for devices directly under the Master in the online tree is the Dynamic/Virtual Devices folder (FIG. 239).

FIG. 239 Master Controller Device Components - Dynamic/Virtual Devices

Note that each dynamic/virtual device uses a single port (Port 1).

Device State Folders

The remaining Device folders categorize NDP devices according to their device state (FIG. 240).

FIG. 240 Online Tree - Device State Folders

• Lost NDP Devices: These devices have been bound to a Master in the past, but have not communicated with the Master for over 10 minutes.
• Bound NDP Devices: These devices are currently bound to a Master.
• Unbound NDP Devices: These ("Orphan") devices are not bound to a Master. It may or may not have been assigned a Device Number. A device will live in this state until it is explicitly bound to a master.
• Searching NDP Devices: These devices have been bound to a Master in the past but is not currently communicating with the Master. After 10 minutes with no communication with the NetLinx Master, a "Searching" device is moved into the "Lost" state.
• Found NDP Devices: A device is "Found" if the device has been bound to a NetLinx Master and is communicating with that NetLinx Master. Found devices inherit the System Number of the NetLinx Master it is "Found" by.

If the device has been configured with a valid Device Number, it will communicate with the NetLinx Master as that Device Number. If it has not been configured with a valid Device Number, it will request a Dynamic Device Number from the NetLinx Master and use the Dynamic Device Number to communicate with the NetLinx Master.

Online Tree Context Menu

Right-click on any device or folder, or click the Display command button (in the Online Tree tab of the Workspace Bar) to open the Online Tree context menu.

for details. | | Network Device Addressing | Click to open the Network Device Addressing dialog. This dialog allows you identify and configure network addressing for Network Devices (devices that are not on the AMX bus, but are connected to a NetLinx Master via the LAN). | | Network Bind/Unbind Device | This item only appears if you have selected a device from the Unbound Devices folder. If the device is unbound, this option binds the device to a specific Master Controller (via the Bind/Unbind Device dialog). See the

Binding/Unbinding Devices section on page 140.

| | Check Port Status | This item is enabled only if a Port item is selected in the Online Tree. The status of the selected port is displayed in the Status tab of the Output Bar. | | Set Identify Mode Command | Click to signal the selected NDP (NetLinx Discovery Protocol) device to start flashing its LEDs so that a user can locate and identify the physical device that is represented in the online tree. | | Online Tree Reporting | Click to access the Online Tree Report dialog. The options in this dialog allow you generate a Online Tree report that summarizes the devices in the active System. | | Reboot The Master | Reboots the selected Master. Note that this option is available only if a Master is selected in the Device Tree. | | Refresh Device Mappings | Click to refresh all device mapping information in the Online Tree. | | Launch Web Control Page via NetLinx Studio | Click to open the Web Control page for the selected device within the NetLinx Studio application. |
