HQSound Realtime RDS Status

Advanced Telemetry & Remote Control with ScriptEasy

ScriptEasy is the revolutionary facility control software developed by WorldCast Systems to give users the power and flexibility to create “Smart” sites; ones that can automatically take action to correct any critical errors that affect operations.

Featuring an intuitive Graphic User Interface (GUI), ScriptEasy incorporates GPIO functions, serial communications, logic operators, live user inputs, timers and more. This allows the site operations to be “scripted”, to allow evaluation of multiple parameters and even automatically engage backup systems, while simultaneously alerting relevant technical personnel.
