Downoad Infinity-Box_cables_pinouts.rar and look at the 'Nec-N343i_Nec-E121.txt'. There are two testpoint pictures too.

btw, you can find there all pinouts , and the arhive is reguary updated ith new supported models.

belive me, If you searsh just a littlebit, Infinity_support and the stickkies can gave ALL the informations you need to operate it easily.

If some unknown error occures ( search first !!!), post it here, you will have help

There is a difference in "i don't see nothing about Nec E121 pinouts" and "some dificult to made a cable".

You need to find Ground pin in cable and connect to phone Gnd.
the try to apply Rx and Tx. If no connection: change Rx <-> Tx.

huzsolt · 11-30-2006, 21:26

I think, your problem was, that you have forgot, that box's RX is the phones TX, and so on.

marcisco2001 · 12-01-2006, 01:20

The problem is to make a conection with Nec E121 because uses a special mini usb and i can find a cable in the market ( my box don't have is the firsts ones ) . to made one i need a special usb conector and i don't now here i can bye. i apreciate any sugestions.

Thanks in advance

huzsolt · 12-01-2006, 10:10

You don't especially need connector, just put RX, TX and GRD to indicated places.

marcisco2001 · 12-01-2006, 13:40

Done!

Thanks for your help!

huzsolt · 12-01-2006, 13:54

You are wellocome.

In addition: Those phones can be unlocked by two connecting methode:
With wires directly to pcb, as you have done it, if you don't have coonector,
or more easily with conector.
Some samsung Hands-free models uses this type of connectors, I think, so in the future you can make one if more Necs will be brought to you to operate them.

Good luck
