Hello.

I've bought two kinds of Nokia cable ,first is cable based on chip:
1.
oti 6858
They've sad me that this is to 3200 and 5100 not for 6100 series.
Datasheet:

I use pin configurations (TX RX),like there is on datasheet ,but something is wrong.And i realy don't know what.
I think that i used any kind of conections, so maybe I can't use this cable to datalogin.

2.
second cable I've bought was ,cable based on

Ark Micro chip 3116S ,but I can't find any datasheet in english

This is for sure DKU-5 cable
I tried to use couple configurations but without any knowledge about this Ark and cable colours configuration
I tried use black as GND,second time white ,but without any results.
And there is no "wrap GND" round the all cables.

I've found drivers for each chips ,but still I have no response from Ecu Control, in some configurations it seems
that I'm conected but I have no data on ecu gauges, I use bin with datalogin.

If someone could give some advice I would be glad.
Is there any hope to run this stuff?

First OTI 6858 is a USB->RS232 Converter not a TTL->USB or TTL->RS-232 like what you need to use. In order to use the OTI 6858 you must use it in series with a TTL->RS232 cable.

ie. 1.ECU (TTL) --- 2.TTL->RS232 --- 3.RS232->USB
