RJ-45 to DB9 console cable wiring problem

[Tyonar]

Hello guys,

 

i'm trying to connect via the console port to reset a Cisco 2960 switch that i recently bought. I also bought a couple of adapters to make it work and it is connected in the sequence :

Console port -> ethernet cable -> Startech RJ45 to DB9 Modular Adapter -> Startech DB9 Serial to USB Adapter -> Laptop

 

Since the RJ45 TO DB9 Adapter is modular, I have to manually wire the pins to the right spots. I found these pinouts to help me :

It looks like this : (Sorry for the subpar pictures)

Then, in Putty, this is what I see :

It loops like that and it seems to be slightly different everytime. i've tried to reboot the switch and it does reboot normally until you get to the "Press RETURN to get started" where it starts to loop again if i press something. I've also tried reversing the black and yellow wires but it only replaces the characters in the loop with non-alphabetical characters. On the tek-tips forum the user "wires" says that he uses the following pinout for cisco console cables :

Quote

Lantronix/Cisco X (special crossover)
2-5  BK, YL, BR, RD+GR
6-8  OR, WH, BL

Again, it did not work.

 

I don't really know what to try next..
