What is it, and why do I need it?
The DN9848E Helix System Controller Software Version 4.03 Host Code is the control programme that runs inside the DN9848E Helix System Controller. This release upgrades version 4.02. We recommend that all users upgrade to this version.

Version 4.03 contains the following new or updated features over V3.xx host code:

Support for 96 kHz compatible AES/EBU digital inputs.

Support for Ethernet communications interface.

Full matrix mixing

Copying and ganging of input and output channels

Provision for back-up of RAM-based system memories into flash memory (change in the use of preset memories).

Support for DN9848 units to be controlled by new ELGAR Add-In.

Fixes to issues with backing up System Memories and LCD contrast.

Fixes to system lockups with setting PEQ parameter settings.

We also strongly recommend that you upgrade an internal component of the DN9848E called an XPort to Version 2.00. Software to upgrade this component is available from this link. It does not matter whether you perform the XPort upgrade before or after the main software upgrade.

The major version number of 4 indicates that it interoperates at a communications level with all other Klark Teknik products running version 4.xx – this includes DN9340, DN9344, DN9340E, DN9344E, DN9848, DN9848E, other Elgar Add-Ins and so on. Note that it is possible to run products with version 3.xx and 4.xx side-by-side, but they must have separate physical communication paths, and the version of the Host Code and Add-In must have the same protocol. See the user manual for more details.
