Hi,

other users have reported using Xantech or other similar connection boxes to distribute the IR signals. I believe most such products use 3.5mm connections whereas Harmony Ultimate uses 2.5mm. Adaptors to go from 2.5mm to 3.5mm are common enough however if you want to go that route.

If your goal is simply to have more, isolated IR LEDs rather than the included mini blasters, we do offer Precision IR Cables which include 4 separate IR emitters on each cable.
