[arm-allstar] DMK URI mic in

[Simon Keys]

Hi all, hope you are well.

I am building a radioless node and having a few challenges getting the mic
to work. I'm using the Alinco EMS-57.

Should I wire the mic out (Pin 1) to Pin 9 or Pin 21 of the URI?

And do I need to use the separate "mic ground" (Pin 7) and if so do I just
short that to the chassis/cable ground?

Many thanks for the help you provide the Allstar community.

Regards
