Access system integration from multiple locations! The Unison AV/Serial Interface station provides a method for PCs or any other type of device capable of RS232 serial communication to control and interact with a Unison lighting control system. The AV/Serial Interface acts as a virtual station with similar functionality to existing station types except that the virtual buttons, faders and rates are manipulated with serial commands. Presets, macros or other Unison station events may be activated or deactivated using this station. Feedback information is passed back in the form of responses and by polling the status of the virtual buttons and faders (similar to the visual feedback LEDs on a standard wall station). The station also outputs Emphasis Serial Button Protocol allowing your Unison architectural system to trigger macros in an ETC Emphasis® entertainment-lighting control system.
