JMRI Hardware Support - Protrak Grapevine System

# Hardware Support: Protrak Grapevine System

## Supported Hardware

### Modules

- Protrak Grapevine Nodes (1-127)

## Limitations

- Fast Clocks are not yet supported. If you have one and want to test it with JMRI, let us know.

## Connecting

### Settings

To configure the connection:

- Open the JMRI "Preferences" under the "Edit" menu
- On the Connections tab, select "Protrak" as the System Manufacturer
- As the System Connection select either
  - Grapevine (ProTrak) Layout Bus
  - Grapevine Simulator
- Click "Save" & restart

Before you can access a Grapevine Node in JMRI, you have to define it to the program. You can do this either from the Preferences window (under Edit in the main menu, click "Configure Nodes") or using the Configure Nodes tool in the Grapevine menu.

Grapevine Systems Names start with a system letter of "G", optionally followed by an integer to form a unique System Prefix. After the prefix, there's a type letter, then a node number and a pin number.
Naming and input/output connectors are described on a separate page.

If desired, check "Additional Conection Settings" and select an option for "Auto-initialize" to have Simulator generate automatic replies from node inputs/outputs:

- Disabled
- All possible
- First 4 per bank

## JMRI Grapevine Tools

The Grapevine menu gives access to:

- Communications Monitor
- Send Command
- The Node Table tool to check whether your Grapevine is working and configure the connected Nodes.
- The Configure Nodes tool.
