Please read the attached ReleaseNotes prior to performing any update. This document always includes the actual information given to the current version of firmware.  



Options available:


A basic firmware package for DC/DS-16 and DC/DS-14. It contains all functions known from these transmitter types except Lua extensions.  




For the experienced users, this option contains the same features as the Standard version. Furthermore, it brings the Lua extension language from DC/DS-24 to all JETI transmitters.  

A few basic applications are included in the Lua package.

The Lua apps can be managed via JETI Studio 1.1.
