dear, u select meter on beep side
and negative (black wire) on ground side and other red wire u can check six point 1 by 1 , but phone should be on and then check
1st u check ground without battery
how
it's simple , 2meter pin u in same ground area its shows beep ,
it's confirm this is ground
then 1 -ve pin u put on ground and +ve pin on six points without battery then there is 1 or 2 points have must ground points , which u have idea that this point is ground ,
then after u put the battery or use power supply to on the set and then u check by meter.
putt meter -ve on ground and check 5points with +ve , it should shows beep
on 1 point then this point is Tx, then after u can easily to check Rx through 1 by 1 connect and check on infinity.
Rx near to Tx
about value through meter , not say confirm
because many set shows different value in RX , Tx
u can't say exact that which 1 is Rx or Tx through value

1. check if phone is MT62xx based.
2. attach charged battery and measure voltage on all available pins and test points.
do you find 2,7-2,9volt pins?
