1U AV Control System with 8 Serial, 8 Relay, 8 IR/Serial & 8 Digital I/O New

When a single room runs a dozen devices — matrices, projectors, DSPs, motorized screens, lighting rigs, and stage equipment — integrators need a control processor with the I/O density to handle it all from one rack unit. The KanexPro CR-HOST8R delivers eight serial ports, eight configurable IR/serial outputs, eight relay channels, and eight digital inputs in a standard 1U chassis. The first four COM ports support RS-232, RS-485, and RS-422 with hardware flow control, and every IR output can be reconfigured as a unidirectional RS-232 port — giving integrators up to 16 serial connections from a single device without expansion modules.

Purpose-built for auditoriums, large boardrooms, houses of worship, and campus-wide deployments, the CR-HOST8R runs on an Android 9.0 platform with a quad-core ARM Cortex-A53 processor. Gigabit Ethernet with TCP/UDP/HTTPS/WebSocket provides IP-based control and monitoring, while onboard IR learning captures remote codes from 20KHz to 60KHz. No proprietary programming tools or annual software licenses are required — configuration runs through open protocols and standard interfaces. Powered by AC 110–220V, the CR-HOST8R mounts in any standard 19-inch rack. Where the compact CR-HOST6S serves single rooms, the CR-HOST8R scales to venues where one controller needs to drive everything on stage and in the house.
