10.6 Ethernet
Regular Ethernet connectors do not deliver the durability and reliability
required by ARRI, so ALEXA uses a 10-pin LEMO connector. An special
cable, available from ARRI (model KC-153-S), is required to connect the
Ethernet socket to a standard RJ-45 Ethernet socket.
It is located on the camera back lower right.
10.7 EVF
The EVF connector is used to connect 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.
10.8 AUDIO IN
The 5-pin XLR Audio connector is currently not in use.
It is located on the camera right lower front.
10.9 RS
The two RS connectors either supply external accessories with 24 V
power and combined load of up to 3 A. The sockets also accept an ARRI
remote start/stop trigger button.
They are located on the camera right lower front.
10.10 12 V
The 12 V connector supplies an external accessory with 12 V power and
up to 3 A current.
It is located on the camera right lower front.
