Info on firmware updates ...
Currently mRS didn't offer any longer FW updates for their devices.
The latest FW is:
-
miniVNApro 2.6 "Firmware V2.6 13/05/2012". If you provide me a proof, that you own a genuine miniVNApro I can provide you the latest FW
-
miniVNAtiny "FW Tiny V1.0 - 22 June 2014"
For historic reasons
Currently two analysers have the feature to update the internal firmware via vna/J.
The process is more or less straight forward:
- Download firmware
- Start vna/J
- Execute Firmware download from the tools menu and follow the instructions
- done
miniVNApro
To gain the full functionality of vna/J, you should install the latest firmware revision.
You should only download the firmware from the mRS web site.
How to install the update on your miniVNApro can be found in the Driver guide for mRS miniVNApro
A video showing the upgrade process can be found here.
Hint: If your miniVNApro refuses to accept the new firmware, the internal bootloader may be corrupt. This can be fixed by reflashing the firmware with an in-circuit programmer. Please contact your hardware dealer for support.
miniVNAtiny
To gain the full functionality of vna/J, you should install the latest firmware revision.
You should only download the firmware from the mRS web site.
How to install the update on your miniVNAtiny can be found in the driver guide for the miniVNAtiny.
I'm experiencing problems with the serial library on Mac OS X machines - the XON/XOFF protocoll, which is required by the new bootloader, is not working as expected.
All other functions are running fine on MAC OS X and vna/J. If you want to update the firmware on the miniVNA tiny please use a Microsoft Windows (XP, VISTA, 7, 8, 8.1) based PC.
