The SDI-B4 Link is developed to get easy control of iris on an analog B4 lens for your URSA Mini and Studio Camera series from BlackMagic Design. Route the return SDI signal from your ATEM switcher between the SDI-B4 Link and your camera, to extract the iris information. The SDI-B4 Link is an independent unit, and requires no further configuration, than selecting the camera number you want to control via the selector switch. The SDI-B4 Link inherits all of the same features as our ETH-B4 Link but will work independently.
The selector switch determines which camera number the SDI-B4 Link control. You can change the switch selector using a small screw driver.
Selector switch 0 = Deactivated
Selector switch 1-C = Camera 1-12
Selector switch D = Test mode (iris close and open fully while the Tally blink)
Selector switch E = Reset calibration to factory default
Selector switch F = Calibration mode (will determine when iris is fully closed/open and save settings, given the factory default values, are not approciate for your particular lens)
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.
