ETHERNET 41
(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 on the camera back mid right.
9.6 ETHERNET
Regular ethernet connectors neither deliver power nor the durability and
reliability required by ARRI, so ALEXA uses a 10-pin LEMO connector. A
special cable, available from ARRI (model KC-153-S), is required to connect
the Ethernet socket to a standard RJ-45 Ethernet socket.
The ethernet port can be used to operate two ALEXA cameras with synced
settings by connecting the cameras with cable KC 156-S, or to connect and
RCU-4 to the camera.
The ethernet connector can output 24 V with 1.2 A power.
It is located on the camera back lower right.
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 very low latency for the viewfinder
image.
It is located on the camera front lower left.
9.8 AUDIO IN
2-channel analog line level audio can be fed to the camera via the 5-pin XLR
connector located on the front right side of the camera.
The audio signal is A/D-converted to 24 bit 48 kHz PCM.
9.9 RS
The two RS connectors supply external accessories with at least 24 V power
and combined load of up to 2.2 A (shared with the EXT connector power
out). The sockets also accept an ARRI remote start/stop trigger button.
They are located on the camera right lower front.
