SKAARHOJ B4 Links

SKAARHOJ B4 Links 

The SKAARHOJ B4 Links are used for remote control iris on B4 lenses connected to BMD cameras. There 
are two models available the Eth-B4 Link which communicates via UDP  connection from a networked 
Skaarhoj controller (TCP when using with Blue Pill devices) and the SDI-B4 Link which receives iris 
command from a 3G SDI feed from either a Blackmagic Atem or another SKAARHOJ controller.
