Background
*****************

A customer wanted a general simplex/broadcast black channel with safety to handle communication from one Simplifier to many Simplifier receivers.
Implementation uses the UART on the display connector to send and receive packets.

Impact analysis (non safety)
****************************
Need new settings.

Impact analysis (functional safety)
***********************************
A new black channel needs to be implemented. See :need:`BLCH0003`.

Affected requirements
*********************

Guideline
*********

* For every approved/decided change, this document shall be filled in.
* To minimize the number of document types, this document is also used for new products, as the Functional Safety aspects are very similar.
* Affected components are the different parts in the technical file that needs to be updated. This includes both Functional Safety parts and non-safety parts.
* Project should be the one project where the work is logged.
* Redmine main issue is the top level issue in redmine that covers the change. It should be within the project.
* Impact Analysis is divided into two parts. The Safety parts need to link to testable verification and follow up in this document.
* Affected requirements are the sphinx requirements that are modified/added/removed.
