10.2.2 Updating the Firmware of Extender Modules via Copy & Paste
The extender modules can be updated via copy & paste using the Mini-USB service port of the extender
modules. The firmware type is part of the file name, e.g. for the MSD firmware
EXTDZMSD.pfw
with the file
extension .pfw
Updating the firmware manually via copy & paste is usually not necessary. We recommend using the
efficient flash update via management software and to manually copy & paste only if a single firmware file
should be updated.
In rare cases, e.g., for the xxxMSD firmware, an update may be necessary to expand the functionality of
certain extender modules for specific requirements. In this case, please contact the technical support of the
manufacturer in advance.
NOTICE
Possible failures when updating the extender firmware
In case the xxxMSD firmware part of an extender module requires an update, there may be dependencies
between the new contents of xxxMSD firmware files and other extender firmware files. In this case,
installing other firmware files before updating xxxMSD firmware files could lead to failed updates.
To proceed successful firmware updates:
Please check the release notes of the firmware package for dependencies between the extender
firmware files.
If you got information from the manufacturer’s technical support that an update of xxxMSD firmware
files of a certain extender module is required, please follow the instructions in this chapter.
NOTICE
Possible update failure with extender modules of the Draco vario ultra Series 493
The extender modules of the Draco vario ultra Series 493 with firmware listed below require special
handling of manual firmware updates. These firmware files cannot be overwritten: FZTDPCPU,
FZTDPCON, FZVDPCPU, FZVDPCON.
When updating an extender module of the Series 493 with one of these named firmware files, the old
existing firmware has to be deleted before copying the new firmware to the extender. Even if there is
the latest xxxMSD file running on the extender.
By updating an xxxMSD firmware via copy & paste, the
Config.txt
file will be overwritten. If there are
parameters set in the
Config.txt
file, they are lost and have to be set again. To avoid resetting the
parameters:
Store the
Config.txt
file before updating an xxxMSD firmware and copy the stored
Config.txt
file
after updating MSD firmware back to the flash drive of the extender module.
To achieve a successful firmware update, proceed as follows:
Always update the firmware with firmware of the same name.
Update all firmware files sequentially.
First update the required xxxMSD firmware part. If several xxxMSD firmware parts need to be updated,
update them one by one, file by file.
If necessary, then update all other firmware files one by one, file by file.
Wait between each copy process until the respective copy process has been completed.
Restart the extender module after all copy processes of other firmware files have been completed.
However, if you are manually updating a single firmware part via Mini-USB service port on an extender
module, we recommend updating all firmware on this extender module.
