Configure Grapevine Nodes

This is the help/jmri/jmrix/grapevine/nodetable/NodeTableFrame help page

The "Node Table" tool lets you see all your nodes at once. Each line in the table corresponds to one node address. The columns are:

The node number
The current status of this node.
This node has been configured in JMRI. You can talk to its Turnouts, SignalHeads, Sensors, etc.
This node has been detected on the Grapevine, but it you need to configure it before you can access it in the program.
The node is not configured, and has not been seen on the Grapevine.
The third column provides a button for you to add a missing node or edit the configuration of an existing node. If you do add or edit a node, remember to save your preferences again!
If the node is configured, there's a button in the 4th column that lets you send the initialization messages to the node. This is useful if e.g. the node has been turned off and on, so needs to be reinitialized. This is only available for configured nodes.

At the bottom of the window is a "Check" button and a status field. Click "Check" to scan the Grapevine to check its status and locate nodes. The status field is:

A scan is starting, but no reply has been heard from the Grapevine yet.
Scan in progress, and the Grapevine seems to be working.
Scan completed OK.
Grapevine failed
Scan completed without hearing anything from the Grapevine. Perhaps the cable isn't completely connected, or some piece isn't powered up.

There's also a "Change Node Board Address" button, which can be used to change the address of a Grapevine node. It opens a new window.
