IR Input (QIO-IR1x4)

The IR Input component represents the single IR Input connection on a QIO-IR1x4 device. Use the component to configure port communication and monitor IR activity to the port.

Inputs and Outputs

Input Pins

This component has no input pins.

Output Pins

IR Input Out

Connect this pin to the IR Source pin of the IR Receiver component or the IR Output (QIO-IR1x4) component. You can connect this pin to multiple IR components (fan-out).

IR Schematic Examples

These examples demonstrate some use cases for all four IR-related components in Q-SYS Designer Software:

IR Driver and IR Receiver, which are located within the Schematic Elements > Components > Control Components category
IR Input and IR Output, which are located within the QIO-IR1x4's Inventory tree.

Sending IR Commands

Example 1: Single IR Driver to a single IR Output

In this example, an IR Driver sends commands for a TV device to a single TV (or perhaps multiple TVs of the same model) in the same room.

Example 2: Single IR Driver to multiple IR Outputs

In this example, an IR Driver sends commands for a TV device to each of the four IR Outputs of the IR1x4. An emitter is placed in each room, and each room has the same model TV. This example shows a hypothetical setup for a restaurant that contains four spaces with entertainment.

Example 3: Multiple IR Drivers to multiple IR Outputs

This example is similar to Example 2, except that two rooms have TVs of one model and the other two rooms use a different model. Therefore, two IR Drivers are required.

Example 4: Multiple IR drivers to multiple IR Source inputs

This example demonstrates how multiple IR Drivers - each for a different IR device - can be sent to multiple IR Outputs, with some IR Outputs sending IR commands from multiple sources. Each room has an IR emitter connected to an IR Output of the QIO-IR1x4.

The Lounge and Entry only contain a TV.
The Bar contains both a TV and a Media Player. Its IR Source Count property is set to '2'.
The Patio has a TV, DVD player, and Media Player. Its IR Source Count property is set to '3'.

Note: For those IR Outputs sending commands from multiple sources (Bar and Patio), only a single IR command can be sent at a time.

Receiving IR Commands

Example 5: IR Input to IR Receiver

In this example, the QIO-IR1x4's IR Input receives IR commands from an IR device – for example, a remote control for a TV that is not in the IR Driver's database. Each command can then be saved and labeled in the IR Receiver component.

Tip: Commands are saved locally within the IR Receiver component within the design.

Example 6: Multiple IR Inputs to IR Receiver

In this example, an IR Receiver can learn commands from two QIO-IR1x4 devices. The IR Receiver's IR Source Count property is set to '2'.

Example 7: IR Receiver configured to send

Similar to Example 5, an IR Receiver learns commands from a QIO-IR1x4's IR Input. However, those learned commands can then be sent to one or more IR Outputs. In this example, the IR Receiver's Enable Transmit property is set to 'Yes'.

Example 8: Receiving and relabeling commands from an IR Driver

In this example, an IR Receiver receives commands from an IR Driver. This is useful for relabeling commands from the IR Driver's database when a different description is desired.

Relaying IR Commands

Example 9: IR Input direct to IR Outputs

In this example, a QIO-IR1x4's IR Input is wired directly to its IR Outputs. This would be useful if you have an IR receiving device in one area but you want to control IR devices in other areas that are out of view of the receiver. The QIO-IR1x4 will simply relay the received commands to its outputs.

Example 10: Multiple IR Inputs direct to IR Outputs

This example is the same as Example 9, except that the Conference Room devices can be controlled from two locations. "Front Desk" represents the IR Input on one QIO-IR1x4 device, while "Conf Rm Hall" is the IR Input on another QIO-IR1x4.

Properties

Name

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Note: This name must match the Hostname for the device as defined in Core Manager or Peripheral Manager.

Location

User-defined name that groups the component with other components in the same physical location – for example, "Rack 1" – or in the same organizational scheme.

Is Required

When enabled, and the device is not found on the network, the device is reported as 'Missing', which is an error condition. This is the default behavior. When disabled, and the device is not found on the network, the device is reported as 'Not Present', which is not an error condition.

Dynamically Paired

Indicates that this virtual component can be paired with the same type of hardware without changing the network ID of the hardware or the name of this component. Refer to the Q-SYS Core Manager Dynamic Pairing topic for more information. The default is 'No'.

Assign component to

Select whether the IR Input is assigned to the Core (default) or an I/O Frame in your design. For I/O Frame, you must also type the Name of the device in your design.

Controls

Carrier Frequency (kHz)

If you know the frequency of the IR receiving device, specify it here, from 26 to 460 (default is 30). Otherwise, use Auto Detect.

Auto Detect

When enabled, the QIO-IR1x4 will attempt to detect the Carrier Frequency of the IR device.

Port Activity

This LED turns on whenever the IR Input port is actively receiving information.

Last Received Code

This is the IR code that was last received by the IR Input. This field remains populated with the last received code until the next code is received.

Active Code

This is the IR code currently being received.

Control Pins

Pin Name	Value	String	Position	Pins Available
Active Code	(text)			Output
Carrier Frequency	26 to 460	26 to 460	-	Input / Output
Carrier Frequency Auto Detection	0 1	false true	0 1	Input / Output
Last Received Code	(text)			Output
Port Activity	0 1	false true	0 1	Output

IR Input and Output Troubleshooting

IR Emitter/Transmitter support

The QIO-IR1x4 works with a wide range of emitters/transmitters from various manufacturers. Devices from Inteset, BAFX, Herfair, and uxcell have been used successfully with QIO-IR1x4. However, these devices can vary widely with regard to pinout, operating voltage, and supported carrier frequency. Refer to the manufacturer's specification sheet to confirm compatibility.

IR Input: "Compromised - IR Rx protocol not recognized" error

This error indicates that auto detection of the IR carrier frequency has failed. You can either try sending a code again (and attempt to detect the Carrier Frequency again) or turn off the Auto Detect control and manually specify a Carrier Frequency based on the IR device specifications.
