Ir extension for freeview stb

To make a long story short my homecast 9200 Freeview box is in a cabinet, so my remote doesn't work.

On the back of the box there is a 3.5mm ir sensor port.

I bought one of these but I'm assuming it doesn't work because it's an emitter and not a receiver. Is that correct?

I've done quite a bit of searching but still none the wiser.

Can anyone point me to a cheap solution?

Thanks
