RX TX Finding In China Mobile


It is tasted and also you can test it.

1 step is, we need to find GND from phone.

2 step is, we should power on phone (operation with dead phone:
phone must be 100% dead by software)and take multimater put it to voltage.

3 multimeter (-) line put it GND and with (+) line check each connectors
, and usually Tx= 1.8v or 2.8v and Rx=1.7v or 2.7v
(it will be change by processor but strongly 1.7v or 2.8v not 3v or 4v)
This way is too easy and you will save a more time.

For example!
You have got new brand China miracle phone with USB cable. It has got
12 pin. You must find (Infinity team give good Idea 1.2.3 punkts):
1) GND usually it has got 2 GND. (now we have got 10 pins)
2) We will uncheck USB + and USB- (VSS) just with checking by USB cable (now we have 8 pins)
3) By USB cable we also uncheck V bat+, ac adaptor + polarization (now we have 7 pins)
4) Now from this 7 pins you will find 1 or 3 not used pins (last operation we have 3 or 6 pins to find Rx Tx signals)
5) Now at last operation you should use good multimeter just to find Rx Tx with 1.7v-2.7v or 1.8v-2.8v
6) WHEN PHONE IS POWERD OFF TX AND GND WITH MULTIMETER MAKING BEEEEEP
(DIOD TEST OPERATION), WHEN PHONE POWERED ON IT WILL SHOW LIKE DIOD
