sprint 2 tnc hooking dilemma



Hello all 
  I need help to setup  sprint 2 tnc from paccomm
  According to the  manual I hooked up all the jumpers  as it mention on the table at page 17 but nothing work 
  The things confused me are
  1-     on page 6 the manual mention
   to operate a sprint-2 satellite model with same baud rate for uplink and downlink; ground the satellite selection line.J2 pin7
  2-     on page 15 mention ground pin 7 to (j2 to pin 6) to activate the dual speed feature
  3-     on page 30 SP5 is closed on all models except satellite model
   
  to work echo satellite I need same speed 9600 for both up and down links 
  so what I should connect? I tried all the different  ways of hooking the pins! but I got no print out from the satellite. the tnc can keying the radio and the dcd diode flickering  ok 
   
  please if anyone could give me the tnc setup i will be graceful
