Variable ND can be assigned to the iris joystick and provides a very smooth control, while iris can still be accessed from the exposure knob

Camera wiring

The FX6 is controlled over IP or LANC.

  • IP control works over LAN or Wi-Fi. LAN requires a compatible USB to ethernet dongle. Most USB-C dongles will not work so make sure to check the USB-Ethernet compatibility
  • LANC can be useful to add tally and menu navigation to IP control. See Sony LANC for this.

Camera configuration

Firmware Versions:

  • The camera needs to be at firmware v4 or higher
  • The RCP/RIO require release 24.1 or above


Authentication has to be enabled for IP control, you will need the login and password for the configuration in the RCP.

When using LAN:

In menu > Network > Wired LAN

  • Enable Camera Remote Control
  • Check your IP address in Detail Settings


Wi-Fi requires a different option. When Wi-Fi is set to Station Mode:

In menu > Network > ST Mode Settings

  • Enable Camera Remote Control
  • Once connected, your IP address is displayed in Connected Network

RCP configuration

Set up a new camera via the RCP Configuration UI:

  • Enter a custom number, name, etc.
  • Select Sony for the brand
  • Select Sony FX6 for the model
  • Enter the IP of the camera
  • Enter the login/password

Make sure the RCP has an IP address in the same range as the camera, follow this guide to add a new IP to the RCP.

Once correctly connected, the camera icon should turn green:


Camera doesn't turn green

Check the following:

  • Ping the camera from a computer
    • Set the computer in the same IP range as the camera
    • Checks the ethernet dongle and camera IP configuration if that part doesn't work
    • If you have the caemra configured as DHCP but don't know if you have a DHCP server, consider configuring static IPs instead
  • Ping the RCP from the computer
    • Ping the IP address of the RCP which is in the same range as the camera
    • This will validate that the RCP and the camera are in the same network/mask.
    • Make sure you assigned an IP address on the RCP if this step doesn't work
  • Disable and re-enable remote control from the network settings
    • The camera is sometimes stuck in uncontrolled mode and doing this change properly re-enables control
  • Power cycle the camera, if necessary remove the battery or PSU

Iris or other lens controls don't work

  • Multiple issues can happen when using Metabones Canon EF Lens to Sony E Mount adapters or the Chrosziel Mount Adapter E-to-PL. If control of other parameters are working fine, it's not likely that the RCP or RIO could be the problem here. The best way to check the camera is to use the CBM or Monitor Sony Mobile apps and test iris, zoom and focus from the app. The RCP uses the same API so should work in a similar way.
  • Using a RIO, it is possible to directly control Servo lenses (B4 or PL) or even motors like Arri CForce (coming) or Tilta. Beside being a proper solution on its own, it can also be a good backup solution when lens control fails from the camera itself

USB-Ethernet compatibility

If you plug an incompatible USB-Ethernet dongle, the FX6 can crash and not even power down when switched off. So between each test, ensure to remove the USB-Ethernet adapter and power cycle the camera before trying a new one.

Most USB-C ethernet dongles will not work on the FX6. Using a USB-A dongle with an adapter has more chances to work but is not ideal for the connection. Here are a few references that have been reported to work:
