5 Firmware update
5.1 Introduction
The X1's operation is managed by a microcontroller. This type of component runs a firmware which can be updated when needed,
for instance to support additional features or to correct bugs. The following sections describe how to update the firmware of your
X1 unit.
5.2 Firmware update procedure
5.2.1 Preparing the firmware image
Before doing the actual firmware update, it is necessary to prepare the firmware update image. Firmware update images are
available in the form of compressed .zip files from our website at www.ch-precision.com.
The following procedure shows how to prepare the firmware image:
1. Start by downloading the latest X1 firmware image from www.ch-precision.com
2. Prepare a blank, FAT32 formatted USB stick. Please note that some USB sticks are not properly detected by the USB
interface of the X1. CH Precision recommends the use of Sandisk USB flash drives such as the one delivered with the unit.
3. Decompress the firmware image .zip file to the root of your USB stick
After doing so, your USB stick should contain the following file:
• X1_xxx.mc1: Firmware update file for X1 Micro-controller
where 'xxx' indicates the software version number.
Make sure this file is present at the root of your USB stick, and that only one version of this file is present. If multiple versions of
the same unit's firmware are present at the root of the USB stick, it can not be guaranteed which one will be loaded as the new X1
firmware.
5.2.2 Updating the firmware
Once the USB stick is ready with the appropriate file, you can proceed with the update of the X1 unit firmware. To do so, follow
these steps:
1. Turn off all CH Precision components connected to the X1.
2. Turn the X1 off by setting the Power on/off switch to off.
3. Disconnect any CH Precision unit from the X1.
