This QSC Q-SYS QIO-S4 Q-SYS Network 4 Serial Communication I/O Expander expands your Q-SYS system's capabilities to enable streamlined interoperability with non-networked control devices via serial connectivity.
By separating local I/O from processing hardware, the QIO Series offers modular and easily scalable network I/O to support your desired topology.
Network Serial Connectivity Where You Need It: The QIO-S4 allows you to provide your Q-SYS system with greater flexibility to deploy serial control connectivity where it's most convenient.
The QIO-S4 features four (4) bi-directional RS-232 serial ports, including one port with RS-422 and RS-485 compatibility, enabling Q-SYS control over lighting systems, video displays, conference systems, and more.
Additionally, each QIO Series I/O expander features a compact form factor that can be rack- or surface-mounted.
Expanded I/O Customization: The QIO Series provides a simpler way to add network I/O connectivity to Q-SYS systems, decoupling the physical location of the I/O from processing hardware to support distributed or centralized processing architectures.
The QIO Series also lets you customize your I/O configuration and complements newer Q-SYS Core models designed with fewer onboard I/O options, including Core Nano, Core 8 Flex, and NV-32-H (Core Capable).
Simplicity and Scalability: Daisy-chain up to four QIO Series devices on a single network run using local daisy-chained DC power. This helps conserve network ports, reduce rack clutter, and simplify future expansion without pulling additional network cables.
Alternatively, QIO Series devices support Power over Ethernet (PoE), providing single-cable connectivity when devices are not daisy-chained.
Designed for Q-SYS: The QIO Series delivers native network I/O customization for Q-SYS, a cloud-manageable audio, video, and control platform designed to provide scalable and flexible AV solutions.
