Hi
I'm trying to datalog my B18C with a P28 and it doesn't work

Remove J12
Remove checksum on my custom tune with chrome
Download the USB driver

My DKU-5 cable
If we start to read from the right side on the phone connector, my cable are

8 Blue
5 Red
3 Green
2 Yellow
1 White

I have read a post who described how to connect the right wire because they change of colors and it says that if you start from the loner wire. The first wire will be Ground, second will be Red for RX and the other will be Green for TX but it doesn't work like that.

I have tried to look the voltage when connect

Ground White
Red 2.5volt
Green 1.15volt

Someone on this forum told that normally you have the TX=5volt and the RX=2.5volt but don't have any 5volt wire.

After that i have try to check with hyperterminal to check if it can echo if i jump the TX and RX wire but just the A on my keyboard will echo when COM3 is open but i don't have to jump any wire. All others button on my keyboard will not echo. I have made that in the past with a DB9 cable and i got it to works but this cable cannot do anything.

I want to datalog and do some RTP with my romulator too so i absolutely need a USB datalog device and the radioshack cable is discontunuity so i cannot buy one. I have 2 DKU-5 datalog wire and they do the same.

I have try to datalog with uberdata too and cannot get it to work too (replace the J12 when using uberdata)

I need some help !!!!!!!!!
Thanks
Fred
