ARRI ALEXA Series User Manual

ETHERNET 51
(model UMC Connection Cable (0.80m/2.6ft) K-UMC3-ALEXA)
 Connecting two ALEXA cameras for synchronized operation
(model EXT to EXT Cable (2.00m/6.6ft) KC 155-S)
The connector is located at the back of the camera on the camera-right
side.
9.6 ETHERNET
Standard Ethernet connectors can deliver neither the power nor the
durability and reliability required by ARRI, so the ALEXA uses a
specially designed 10-pin LEMO connector. The ARRI KC-153-S cable is
required to connect the Ethernet socket to a standard RJ-45 Ethernet
port.
The Ethernet port can be used to operate two ALEXA cameras with
synced settings by connecting the cameras with a KC 156-S cable, or to
connect the Remote Control Unit RCU-4 to the camera.
The Ethernet connector can output 24 V with 1.2 A power.
The connector is located at the back of the camera on the camera-right
side.
9.7 EVF
The EVF connector connects the camera to an EVF-1 electronic
viewfinder. The signals on this connector are proprietary and can only
be used to drive an EVF-1. This proprietary signal assures low latency
for the viewfinder image.
The connector is located at the front of the camera on the camera-left
side.
9.8 AUDIO IN
2-channel analog line-level audio can be fed to the camera via the 5-pin
XLR connector located at the front of the camera on the camera-right
side.
The ALEXA converts the audio signal from analog to 24 bit 48 kHz PCM.
