1573 – ActivExpression2 firmware upgrade information

Applicable to:

  • ActivExpression2


  • ActivHub


Upgrading firmware

Firmware is a small program on Promethean devices that controls basic functionality.

What do I need?

  1. 2.4GHz ActivHub
  2. ActivExpression2 devices: We recommend that you upgrade all ActivExpression2 devices at the same time. It is not necessary to register the ActivExpression2 devices to the ActivHub before upgrading.
  3. A computer with ActivDriver version 5.5 or later: If you are using a laptop for the upgrade, we recommend that you connect the charger. If this is not possible, ensure the battery has sufficient charge to complete the upgrade. If you are unsure, do not perform the upgrade until the battery has been fully charged.

Before you begin

Ensure that you are using ActivDriver version 5.5 or later by clicking the ActivManager icon in your system tray or toolbar.
Select Control Panel and check the version at the bottom of the window.

If you do not have ActivDriver version 5.5 or above, please download the latest version for Windows and Mac from our Support Site. Linux users should visit article 1017.

You must follow the steps in the order they are listed in this article, starting with the ActivHub firmware upgrade before moving on to the ActivExpression firmware upgrade. Do not disconnect the ActivHub at any point during the firmware upgrade; doing so may damage the ActivHub.

ActivHub firmware upgrade

Please follow the instructions in article 1621.

ActivExpression2 upgrade

Just like the ActivHub firmware upgrade, the ActivExpression2 firmware upgrade is controlled by the ActivManager on your computer. Once the process has begun, ActivManager will continue to broadcast the upgrade until you stop it.

Select ActivExpression2 from the list of hardware and click Upgrade.

ActivManager will begin to broadcast the upgrade and the progress bar will advance from 0% to 100%. This will happen repeatedly until you stop the upgrade.

Whilst the upgrade is being broadcast, turn on the ActivExpression2 devices. Press the MENU button, use the cursor control key scroll down to RF Upgrade and press Select.

A progress bar will appear on the ActivExpression2 screen. Once it reaches 100% the device will switch off automatically. This means the firmware upgrade is complete.

Once all devices have been upgraded, click Stop in the ActivManager window. A confirmation dialog opens; click OK then Close.
