# JdmTool

A command-line tool for downloading and transferring Jeppesen databases aiming to be compatible with [Jeppesen Distribution Manager](https://ww2.jeppesen.com/data-solutions/jeppesen-distribution-manager/).

It requires a Jeppesen subscription, and currenty supports the following services:
- NavData for Garmin GNS 400/500 Series
  - Requires a Skybound data card programmer (USB ID `0e39:1250`)
  - Requires a 16MB NavData WAAS card or a 4MB NavData non-WAAS card
    - If you have an 8MB data card, please [file a bug](https://github.com/dimaryaz/jdmtool/issues/)!
- NavData and Obstacles for Avidyne IFD 400 Series
- (Very experimental) Garmin G1000 support
  - If you try it, please [file a bug](https://github.com/dimaryaz/jdmtool/issues/) to report your results - even just to say "it worked".
  - Services other than Electronic Charts should produce byte-for-byte identical results to JDM, and are expected to work.
  - Electronic Charts _may_ work, but are completely untested! See [more info here](ElectronicCharts.md).


It is mainly tested on Linux, but should work on OS X and Windows.

## Installing

You may want to create a Python virtual environment using e.g. [virtualenvwrapper](https://pypi.org/project/virtualenvwrapper/).

Install the latest `jdmtool` release:

```
pip3 install jdmtool
```

Or install the latest code from GitHub:

```
pip3 install "git+https://github.com/dimaryaz/jdmtool.git#egg=jdmtool"
```

### IFD 400 and G1000

You should install an optional Just-in-Time compiler by running:
```
pip3 install jdmtool[jit]
```

This should significantly improve transfer speeds.

### GNS 400/500

Make sure you have access to the USB device. On Linux, you should copy `udev/50-garmin.rules` to `/etc/udev/rules.d/` and possibly reload the rules.

## Basic Usage

### Log in

You only need to run this once (unless you change your password).

```
$ jdmtool login

### Download the database

This is optional - the next command will automatically download the database as needed - but can be useful if you want to transfer the database when you are offline.

```
$ jdmtool download 0

```

### Transfer the database to the data card (GNS 400/500)

```
$ jdmtool transfer 0
Found device: Bus 001 Device 052: ID 0e39:1250

```

### Transfer the database to the USB drive (IFD 440 or G1000)

You can specify a single service ID, or multiple IDs separated by commas.

Note: the final database file requires the FAT32 volume ID of the USB drive. `jdmtool` will attempt to find it automatically - which requires the destination to be an actual FAT32-formatted device, not any random directory. Alternatively, you may set the volume ID manually using the `--vol-id` parameter.

> Getting the volume ID automatically is currently not supported on Mac OS, so you will need to use the `--vol-id` parameter. You can try [these instructions](https://apple.stackexchange.com/questions/408562/how-can-i-get-the-volume-serial-number-of-a-fat-volume) for finding the volume ID.

```
$ jdmtool transfer 0,1 /run/media/user/USB/

  Avidyne IFD 400 Series, Bendix King AeroNav Series - NavData
