This QSC Q-SYS QIO-IR1x4 Network IR I/O Expander adds networked infrared and serial control connectivity to Q-SYS systems. It provides one IR receiver input and four configurable IR or RS-232 transmit outputs. Q-LAN networking, Power over Ethernet (PoE), and flexible mounting options make it suitable for distributed AV control installations.
The QIO-IR1x4 allows Q-SYS systems to control compatible non-networked devices, such as displays and media players, through infrared or serial connectivity. Each of its four output ports can be configured for IR or transmit-only RS-232 operation.
IR carrier frequency and drive strength are configurable, while the RS-232 baud rate can be configured through Q-SYS Designer Software. LED indicators provide local IR transmit activity feedback.
The QIO-IR1x4 can be powered by PoE or an external 24 VDC power source. Up to four QIO Series expanders can also be daisy-chained on one network run when local daisy-chained DC power is used.
