TestMyMiniTiouner v0.2a => hardware incompatible

Postby G4KLB » Fri 13 Apr 2018 22:36

I think I must do a little mod to my MiniTiouner V2.0 for it to be recognised.

Hello Colin

Yes, now I must be able to recognize a great familly of different MiniTiouners.
For the MiniTiouner v2, you must add a resistor of 4,7k or 10k between the ground and CN2-19 (or change the Name in the eeprom using FTprog 'MiniTiouner' instead of 'USB <-> NIM tuner' )
after talking with Noel and Brian, they said it was easier for people just to add a resistor.

There is an article about that in the last CQ-ATV:

Automatic hardware detect
Minitioune V0.8 is compatible with all versions of hardware and automatically detects the version of hardware in use – to enable this function to work with the BATC MiniTiouner hardware you need to add a 4.7k or 10k resistor between pin CN2-19 of the USB module and Ground before running the software.
You can do this on the Mini module or on the main PCB as shown in the following pictures:

or you can do it under the pcb:

You must do it also if you want to use the new version 0.8 of Minitioune that will be available very soon.

Many thanks Jean-Pierre, I suspected this was the case but thought it was worth posting as others would encounter the same issue.
I will add the resistor to all of my V2.0s.

Looking forward to the release of the new version 0.8 of Minitioune.
