====Use the timecode in Blocks====
There are a few steps to do before we can make use of the incoming analog timesource in blocks.


===Enable the driver===
The driver to handle the timedata from the LTC-reader software is not enabled by default. 
To enable the driver you must make sure the driver files exist in the script/driver directory in the PIXILAB-Blocks-root. The TimecodeLTC driver is stored in the script/driver-archive/ directory and needs to be enabled:

Change to the script directory: 
 <code> cd /home/blocks/PIXILAB-Blocks-root/script </code>

Move the driver files to the drive directory:
<code> mv /driver-archive/TimecodeLTC.ts /driver-archive/TimecodeLTC.ts driver/</code>

Restart the blocks server: 
<code>systemctl --user restart blocks.service</code>

The driver is now available to use on network devices. 
===Setup the network device in blocks===

Under the page Manage/Network we set up a new device and assign the TimecodeLTC driver.
The port is predefined in the driver to match the default configuration to the Timecode reader on the server.

===Configure the driver===

You must configure the driver for the expected timecode type. This can be done with one of the following methods:

A. Set the 'type' property of this Network Device to the expected type.
This can be done using a Task triggered on system start-up or the 'connected' appears on the network).

B. Set options using JSON data in the "Custom Options" field of the Network Device, like this: {"type": "29.97_drop", "offset": 0.0} Supported type values: "24","25","29.97_drop","29.97_nondrop","30".

===Connect a Blocks timeline to sync with timecode===

Create a timeline block, it can be left empty for testing purposes. 
Set the timeline to use External synchronization in the timeline settings. Select your LTCTimecode device as sync source property.

Apply any time offset as required. This timeline is now controlled by the timecode.
