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 locally before updating an xxxMSD firmware.
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 copying operations of the other firmware files are 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.
Preserving the Parameters of the Config.txt File
To store the
Config.txt
file before updating MSD firmware, if parameters have been set, proceed as follows:
1. Connect the extender module to any source using a Mini-USB cable.
The extender module opens a flash drive containing the
Config.txt
file.
2. Copy the
Config.txt
file from the flash drive and paste it to a local directory of the connected computer.
