ALEXA LF SUP

ALEXA LF SUP 4.1

Software Update Package LF SUP 4.1 provides a critical bug fix for an error that prevents the camera from booting correctly.

We strongly recommend updating all ALEXA LF cameras that currently have LF SUP 4.0 software.  Cameras with LF SUP 3.0 or earlier are not affected.

LF SUP 4.1 requires LF SUP 3.0 Software & Hardware Upgrade

LF SUP 4.1 should only be installed on ALEXA LF cameras that have previously undergone the "ALEXA LF 3.0 Software & Hardware Upgrade", which can be performed free-of-charge by ARRI service. The ALEXA LF 3.0 upgrade includes the upgrade of an electronics board (ACDA3 gets exchanged for ACDA4), and LF SUP 4.0 and 4.1 require the ACDA4 board. LF SUP 4.1 will not run on ALEXA LF cameras with the older ACDA3 board installed (any camera running LF SUP 2.0 or LF SUP 2.1). 

Upgrade Paths

  • If your ALEXA LF has LF SUP 2.0 or 2.1: contact ARRI Service to schedule your free upgrade to "ALEXA LF 3.0 Software and Hardware". ARRI service will then also install LF SUP 4.1. More information about the "ALEXA LF 3.0 Software and Hardware Upgrade" can be found below.
  • If your ALEXA LF has LF SUP 3.0: Download LF SUP 4.1 and install. You do not need to install LF SUP 4.0 first.

Downgrading

Once LF SUP 4.1 is installed, it is possible to revert back to LF SUP 4.0, but not to LF SUP 3.0 or older. However, due to the nature of the issue that 4.1 avoids, it is not recommended to downgrade to LF SUP 4.0.
