QIO-IR1x4

The Q-SYS QIO-IR1x4 is a network control endpoint native to the Q-SYS Ecosystem, serving as an IP-to-IR bridge that enables network-based infrared control distribution. The compact form factor includes surface mounting hardware permitting discreet and strategic mounting while an optional rack kit fits one to four devices into a standard 1U nineteen-inch format. Up to four devices may be daisy-chained off one access switch port, provided +24 VDC power is available. Alternatively, each may be individually powered over Ethernet.

Note: This topic provides an overview of the QIO-IR1x4. For specifications and installation documentation, see the QIO-IR1x4 product page on the QSC website.

You can perform either a short reset or long reset:

  • Use a Short Reset to restore connectivity to a device in the event that unintended network settings were specified in Q-SYS Peripheral Manager or the device is otherwise unreachable. A short reset will restore device IP settings back to Auto mode (DHCP) and delete all Static Routes. The configured hostname is retained.
  • Use a Long Reset to restore the device to factory condition. This is useful for deeper troubleshooting, or when preparing the device for decommissioning or transfer.

    CAUTION: A Long Reset clears all network settings (including hostname), disables 802.1x, deletes user-installed device certificates, deletes all logs, and clears the device password.

Performing a Short Reset

  1. Press and hold the Reset Button until the Status LED (NL, NM Series) or Power LED (QIO Series) begins flashing blue slowly – approximately 10 seconds.
  2. Release the button before 20 seconds elapse.
  3. The device performs its prescribed Short Reset and reboots.

Note: To cancel the Short Reset, release the button before 10 seconds has elapsed.

Performing a Long Reset

  1. Press and hold the Reset Button until the Status LED (NL, NM Series) or Power LED (QIO Series) begins flashing blue rapidly – approximately 20 seconds.
  2. Release the button when the LED begins flashing rapidly.
  3. Within 30 seconds, press the Reset Button again to confirm the reset.
  4. The device performs its prescribed Long Reset and reboots.

Note: To cancel the Long Reset, do not press the Reset Button again during the 30 second confirmation period.
