FEATURES

 IMPROVEMENTS

• Updated CRMX Firmware - CRMX firmware updated to V1.1.1.5
• sACN Framerate Improvement - maximum sACN framerate increased from 40 fps to 80 fps for V24
• Master Mode Dimming Curve - When receiving control from another fixture, Vortex will match the dimming curve of the transmitting device
• V24 Reliability Improvements - Reduced start-up errors on V24 related to fan board and LED driver board communications.  Add automatic recovery from 'stuck' zones.  Reduced startup current to prolong fixture life

• sACN Universe on webspage now shows all characters
• Smoother ramping of fan speeds
• Overtemperature Protection - If error detected with fan board, limit maximum temperature to 65°C to protect device
• V24 Ethernet Resets - Reduced V24 Ethernet resets that could potentially interrupt sACN
• Vortex Soft Webpage Icon - Fixed issue with incorrect model shown on webpage control menu when in multizone, split, bars or grid DMX mode
