How To | Set up ECP on a Q-SYS Core processor

Updated at June 6th, 2023


The Q-SYS External Control Protocol (ECP) is the original Named Control -based external control protocol that has been available since version 1.0 of Q-SYS Designer Software and firmware. Though ECP has been superseded by the newer Q-SYS Remote Control Protocol (QRC), it is still supported in all versions of Q-SYS. Therefore, If you have developed code on a third-party control system for using this protocol to control Q-SYS, you do not need to rewrite any code to use QRC.


To learn how to use ECP, see the External Control Protocol (ECP) topic in Q-SYS Help.
