Operation of the Camera 137
14.5 Syncing the Settings of Two Cameras
Two ALEXAs can be operated with synchronized settings. ARRI recommends to sync
the settings of the same ALEXA models only, for example, two ALEXA Plus models.
Camera connection
The settings of two ALEXAs can be synchronized over ethernet using the ALEXA
Ethernet/Ethernet Cable KC 156-S, or over an ethernet hub using the ALEXA
Ethernet/RJ-45 Cable KC 153-S.
Camera setup
To sync the settings of two ALEXAs over Ethernet:
1. Connect an ALEXA Ethernet/Ethernet Cable KC 156-S to the EXT ports on both
ALEXAs, or an ALEXA Ethernet/RJ-45 Cable KC 153-S to the ethernet hub and
the EXT port of each ALEXA.
2. In the System menu on the master camera, select External Sync.
3. On the EXT SYNC screen, set Settings sync to ETH master.
4. In the System menu on the slave camera, select External Sync.
5. On the EXT SYNC screen, set Settings sync to ETH slave. The two ALEXAs
will automatically negotiate IP addresses. It takes approximately five seconds to
establish a connection.
The master camera will initially distribute its settings to the slave camera. Once this
is done, settings can also be changed on the slave camera, and the change will
take effect on both cameras. This is useful if the master camera's controls are not
accessible.
If a camera is set to ETH master or ETH slave, but is not connected to another
camera, a warning is displayed on the STATUS Info screen.
