remote control can be switched between these protocols.

• The NEC protocol have to be used for Barco projectors based on the Pulse platform: F70, F80, F90, HDX 4K, UDX, ...
• The RC5 protocol have to be use all other Barco projectors: HDX W, HDF W, HDQ 2K, ...

Remark with RC5 protocol
Not all buttons of the Pulse RCU are one-to-one compatible with the legacy Barco RCU. Button pairs SHUTTER open/close and
POWER on/off emit the same code (per pair) when in RC5 mode, because the legacy RCU's only had 1 button for Shutter and 1
button for Standby.
