Using 2-bit Rotary Switch for Otto

[jordo81]

Dear all,

I try to find a ground on the 2-bit rotary switch to switch the Otto board.
I have configured the Otto according to the integration guide with VCC to S with a 4k7 resistor.
Any suggestions how I could get this to work?

Thanks,

Jordo

The 2-bit Rotary Switch board is generally for controlling the 4:1 MUX, not the OTTO (four positions, not two).

The outputs of the board are either high(1) (V+) or low(0) (ground). 00, 01, 10, 11.

Hi Brian, thanks for the reply. I thought I'd read somewhere that this switch could be used for that purpose.
I'm not using the 4:1 but I want to switch between 2 sources via the OTTO. I now use a SPST switch but using the rotary switch would be a more integrated solution.

Well, you certainly could. You just need to connect it's V+ and GND to the OTTO's V+ ad GND, then use the regular outputs as the trigger source.

Because it has four positions, it will be a little weird, but possible.

A little weird as in that you use only 2 of the 4 portions of the rotary switch?
I will remove the EXT IO connector from the BIIISE DAC Board and dedicate the rotary switch to the OTTO.

I will try that thank you!
