I did a lot of searching using the search feature and only found this info! that i need a
twisted cable (null) = 2700

from my 2700, i also owned a Fortec but that has a:

straight thru cable


so i need to buy a new cable to fix my pansat 2700????

Yes a different cable is needed or i believe rs makes an adapter also.

Cables run for 5 to 10 dlls but you can build your own

Pansat 2700 or Spacestar receivers need null model cables

straigth cable goes from pin to pin
9 PIN Female to 9 PIN Female RS232 serial cable
thats used to program most FTA receivers like the Fortec Star
and Pansat 2500 receivers.

ok thanks!! a lot it really helped!
