Connecting the RCU-4 to an ALEXA
The RCU-4 is connected to the camera by cable.
Two different cable lengths are available:

KC 157-S

(3.25’)
K2.72041.0
Connect the male plug of the cable (black cable sleeve) to the
ETHERNET port of the camera and the female plug (blue cable
sleeve) to the RCU-4.
Either cable can be extended with an extension cable. Please note
that the extension cable on its own cannot connect the RCU-4 to the
camera.
KC 159-S
15m (50’)
K2.72043.0
Multiple extensions can be connected to each other, however, the
maximum allowed cable length between camera and RCU-4 is 47m
(154’). Thus three KC 159-S plus one KC 157-S can be combined.
Note: Do not kink the cables! The minimum allowed bending radius is 70mm (2.75”).
