Force10 S50 Console issue

Hello,

I have 2 Force10 S50 switches. When they were in the datacenter i was able to use the console port. However, now that they are home i want to reconfigure them for a new datacenter. The way i have it setup is USB to Serial > Serial to RJ-45> Rollover Ethernet cable. With this setup i can see output in putty but cannot type anything. If i use a straight through or a cross over it does not display anything. Can someone help me troubleshoot this. I never had so much trouble with getting a console port to respond to me. Both switches have the exact same issue so i know the switches are good. Must be my RJ-45. I've made it 3 times and no change. If i bring over a cisco switch my usb to serial and cisco cable work perfectly. I've tried the desktop and the laptop. 

Thanks,

Tom
