Updating the CR Firmware
From time-to-time, Tiptop releases firmware updates to some of its modules including the CR. The-
se firmware updates include changes to the hardware that fix bugs as well as add new features or
improve current features. Firmware updates are applied to the CR via a USB flash drive (memory
stick) connected to the USB port on the module back.
The CR features a USB type A port that hosts USB 1.0 and 2.0 devices. Any flash memory device
can be used, but the CR only recognizes a drive formatted in the MS-DOS FAT32 format. This is the
default format of most USB flash drives and SD cards out of the box, so no need to reformat unless
the drive was formatted to something like the Mac HFS or Windows NTFS format.
(Note: the power draw of an external IDE/SATA drive is too much for the CR to support, so don’t plug
in an external USB hard drive of this type.)
To load the firmware on to your USB device:
• Download the firmware file from the Tiptop site
• Copy the file onto the root level of your USB drive. The downloaded firmware file is
called image.hex and the CR will only recognize files with this name.
Follow these remaining steps to update your CR:
• Power down the CR and unscrew from rack
• Insert the USB flash drive into USB port on the back side of the CR
• Hold down the Vertical button on the lower right
• While continuing to hold down the Vertical button, power on the CR
• Firmware update takes about 5 seconds and the Swing LED will light
• Once the firmware is updated the CR will boot normally
• Remove USB drive and reinstall the CR into rack
It is sometimes recommended to erase the internal memory after firmware upgrade. Here is how
you do that:
Clearing the Internal memory
The internal memory that holds all data and settings while power is off can be reset if desired. Hold
the Zoom button down on power up and the memory will be set to default values.
Checking Firmware Version
To display the current firmware version, Press the Global button while in Vertical View. Once the
display changes to Global View, press the A button (seventh button in the Group Column) and the 3
digit firmware version will display for a few seconds.
