Pinouts for B889:
2 = RX_B
3= RX_A
4= TX_B
5 = TX_A
6 = GND

I have also problems with my B889 slave CPU IMEI, have tried to get help from multibox team, but nothing still going with only one SIM

Maybe going to scrap whole multibox and buy an Infinitybox, they seem to have better support.

Hi, i am so new to the forum. As far as i know for this model (b889) no need to use any box. They had a program which they can use to access the machine via USB cables. I dont know where can u get it but i saw it and used it in China, but unfortunately i cant share it. company rulez

If possible can somebody show me how to reach the phone via boxes?

Cheers!
