Programming 2700A........

[Tmac]

I have been programming Pansat 2500A 's, now I have aquired a 2700A for a friend. I have been using a usb to serial adapter 9 pin for the 2500. I understand now I need a null modem for the 2700A. I bought a null modem adapter and connected it to my cables but when I try to write to the 2700A, I get a write failed.
I am using blacklist 1.4 to write same as 2500A. Any help or direction to get help would be appreciated. Thanks T

2700 comes with the cable, Just use that one. GT loader and bin 143 are working fine however you will need to enter the public keys the first time in the parental control2 screen the first time or it will sit on waiting for pic forever..
