Bc2000 (for the BCF2000 & BCR2000)

hi,
I'd command panning with the bcf but I probably lost a step in the
various explanations.
the 01v96 pan  data string is:
left side $F0 $43 $10 $3E $7F $01 $1B $00 $00 $7F $7F $7F $41 $F7
center    $F0 $43 $10 $3E $7F $01 $1B $00 $00 $00 $00 $00 $00 $F7
right side$F0 $43 $10 $3E $7F $01 $1B $00 $00 $00 $00 $00 $3F $F7
 then
$encoder 1
  .showvalue on
  .mode 12dot
  .resolution 96 96 96 96
  .default 0
  .minmax 0 127
  .tx $F0 $43 $10 $3E $7F $01 $1B $00 $00 $7F $7F $7F val $F7
 and the pan work just half portion of course.
i
I've tray to change the variable but nothing.
where i mistake
i hope someone can explain 
all the best
