Sadelta Echo master plus classic ud.

[Russ63]

Hi Guys. I have just come across one of the base mic's mentioned in the title above, but. Try as I might, I can not find ANY information about it anywhere.
Plenty for the echo master plus classic, but nothing for the UD model with the up/down switches.
Does anyone hereabouts know the mic wiring for this, er, oddball mic to fit an Alinco DX70 please ?.
Many thanks.

MASTER CLASSIC PLUS + UP / DOWN
AUDIO - WHITE pin1
RX - GREEN not used
TX - BROWN pin2
UP - DOWN BLUE - GREY pin4 up pin3 down
SHIELD ground pin8
! + 12 VOLT - RED
you may need to add a mic ground to pin 7 if so use the spare rx wire and rewire it

this info was got from the net and i dont know if correct check your self with a multi meter first to make sure you dont short out the + voltage on one of the mic pins ......if in doubt dont try
