About ProfiLux firmware updates
Firmware updates allow your ProfiLux controller to benefit from the newest available features and improvements. With the use of GHL Control Center and USB connection, you can update the firmware of your device by closely following the steps shown below.
What you will need
In order to do this kind of update, you will need the following:
| Item | Purpose |
| Windows computer | For connecting to your GHL device via USB on GCC |
| USB cable | For connecting to your GHL device via USB |
| GHL Control Center installed | For performing the firmware update |
Before you proceed with the steps below, you must first download the newest version of GHL Control Center. This will allow you to have access to the newest firmware version for your GHL device.
To download GCC, visit our downloads page and install the program to your PC.
Performing the firmware update
1. Open GHL Control Center (GCC) and connect to your GHL device via USB
If you are not sure how to connect, follow the steps shown here to connect via USB. Once you are connected, you may proceed with the steps below.
Before proceeding with a firmware update, we highly recommend you backup your device settings and sensor data. Doing so will ensure that you have a backup of your original settings if you need them. Depending on how large of a firmware jump you are doing, it is possible you may need to use your backup file to restore your original controller settings and probe calibration data.
To backup your controller settings and probe calibration data, click the Backup and restore tab.
- Select Transmit all settings from ProfiLux to file to create a backup file of your settings.
- Select Transmit all sensor data from ProfiLux to file to create a backup file of your probe calibration data.
If you are using virtual sensors (ProfiLux 3 and higher), make sure you write down the control settings for these sensors as they will not be included as part of the backup settings file. Depending on the extent of the changes in the firmware update, if the ProfiLux is reverted to factory settings, at least you’ll have your virtual sensor info ready to re-enter.
Don’t remember how to create virtual sensors?
