Modular units have the ability to receive Infra-red(IR) commands in two different ways; Code-based IR and Contextual based IR. Code-based IR uses unique codes for each room/output, whilst Contextual IR uses a single set of codes, with the unit determining where the IR command originated.
If you wish to revert the unit to Code based IR control please edit the settings.ini file on the SD card (Please use only PC based systems to edit the SD card contents) and remove the following information.
cir1 = 0x00ff9867
cir2 = 0x00ffd827
cir3 = 0x00ff8877
cir4 = 0x00ffa857
cir1 = 0x00ff807f
cir2 = 0x00ff00ff
cir3 = 0x00ff30cf
cir4 = 0x00ff906f
Finding the IR window on your source device can be difficult if it isn’t mentioned in your user manual or is marked clearly on the front of your device. A very common device is Sky+HD and Virgin’s Tivo boxes. Below, we’ve marked where the IR windows are on these devices for easy installation.
THOMSON model DSI8215
PACE model TDS850NB
Amstrad model DRX895
Sky multiroom box
Sky HD Terabyte box

What is two-way IR?
With one way IR, the IR travels “backwards” from the TV location to the location of your source device or central matrix. The addition of a “forward” IR path means that IR can be sent 2 ways along the transmission cable, known as “two way IR”.
The “forward” IR path takes IR from the central location to the location of the receiver part of the product you are using. Normally this will be the location of a display or projector.
This is where one IR passback system is passed into another. So the IR emitter from one IR passback system is pointed at the IR receiver of another and the IR code is repeated a second time to the IR emitter on the second IR passback system.
When you push a button on one of your remote controls at home, a short burst of infrared light is emitted from it (normally from the top at the front of the remote). This short burst of light contains information about the button you have pushed. When this light reaches your source device (sky box, Apple TV etc) it is interpreted and the function of the button you have pushed (stop, play, pause etc) will be performed.
IR over HDMI Injector Kit setup guide
1. Install the HDMI IR dongle between the HDMI input on the TV and your HDMI cable. Ensure that the switch is set to “IR”. Plug the IR Receiver (see ‘Pack Contents – 2.’) into the stereo jack input on the dongle (labelled RX).
2. Position the IR Receiver ( see ‘Pack Contents – 2.’) with clear line-of-sight to the remote.
3. Install the HDMI IR dongle betwen the HDMI input on the source and the HDMI cable, similarly to point 1. Again, ensuring that the switch is set to “IR”.
4. Plug the IR Transmitter (see ‘Pack Contents – 1.’) into the stereo jack input on the dongle (labelled RX on the dongle).
5. Position the IR transmitter ( see ‘Pack Contents – 1.’) with clear line-of-sight to the remote receiver on the source.e.
1. IR Transmitter
2. IR Receiver
3. IR Dongle (both labled RX)
Basic IR Setup (dos and don’ts)
When attempting to troubleshoot any issue, we need to isolate where the root cause of the fault could lie by a logical process of elimination.
At the start of a troubleshooting process, never rule out anything as not a potential cause of the problem. Every aspect of the installation should be considered as a potential suspect. Each component of the installation should be ruled out one-by-one and only then eliminated from the troubleshooting process as the potential problem.
NB: Both dongles have ‘RX’ moulded into the casing.
When using the IR over HDMI function, ensure that the switch is pushed across to ‘IR’ and not ‘CEC’.
Connect the dongles into the source device’s HDMI output port and the display device’s HDMI input port, initially without the HDMI cable connected.
Connect the IR cables. Connect the IR TX cable to the dongle that’s connected to the source device and connect the IR RX cable to the dongle connected at the display.
In order to use your source device remote(s) at the TV location, ensure that the IR RX cable receiver eye is fully inserted into the 3.5mm jack port on the dongle and the IR RX cable magic eye is positioned in sight of where you would usually like to point the remote control(s).
Connect the IR TX emitter cable to the 3.5mm jack port on the source device dongle and position the IR emitter in sight of the IR receiving window on that connected source device.
TIP: tape the TX cable flat to a piece of card sat under the source device pointing at the IR window
When using the IR over HDMI kit is set-ups involving splitters/switches/matrices, remember that the IR dongle has to be connected at either ends of a single HDMI cable run. So the dongle will be connected to the HDMI output port of the splitter/switch/matrix and not the HDMI output of the source device. To control the desired source device(s) – ensure that the IR TX emitter cable is positioned in sight of the IR receiving window on that connected source device.
The exact position of the IR window can vary between makes and models of source. Generally it is on the left hand side about 2 inches from the middle of the box. Often it can be a bit of trial and error to locate the optimum IR emitter placement position. Once found I would advice taping/fixing the emitter in place.
A final tip is to ensure that the batteries in your remote control are at full strength. (It’s amazing how a fresh set of batteries can resolve weak IR issues).
