With the ETH-B4 Link you have the power to control iris on an analog B4 lens mounted on the URSA Mini and Studio Camera series from Blackmagic Design. You connect the lens via the Hirose 12pin connector (see details below), which provide power to the lens and let you adjust iris via the ATEM CCU or the ATEM CCU Lite. Camera number is selected via the selector switch - we even managed to provide preview tally via the 3-pin phoenix connector! Please note the ETH-B4 Link is an upgrade of the well know ATEM-B4 Link, and it inherits almost all of the same features. The ATEM-B4 X model is no longer available.
Selector switch 1-8 = Camera 1-8
Selector switch 9-C = Deactive
Selector switch D = Test mode
Selector switch E = Reset calibration to factory default
Selector switch F = Calibration (will find iris end points)
The Hirose 12pin connector supports most B4 lenses, but it’s your own responsibility to check that your particular lens has the features described below. Two example pin outs are given to the left from manuals for cameras and lenses, so you should be able to look up and check similar information for your lens.

Please be aware you might expect vignetting depending on your lens, the sensor size and the type of mount adaptor used. SKAARHOJ takes no responsibility in this regard. Check with your camera/lens supplier.
The ATEM CCU or the ATEM CCU Lite are required as base stations. Two ATEM CCU Lite controllers can work together to operate up to 8 cameras. The ATEM CCU can also operate up to 8 cameras. The ATEM CCU can be used as an master station simultaneous with a ATEM CCU Lite controller. Iris adjustments made in the Software Control Panel will be reflected on the ETH-B4 Link Micro (CCU or CCU Lite still required).
The ETH-B4 Link Micro will work on cameras other than the BMD Studio Cameras, but only for iris control.
Buy a controller ready to work out of the box.
