You can use fold -1 to split, e.g in ksh....
Code:
word="08FD3 03A26 000FA0 FFFF0 BBA0F 00000 00000"
echo $word | fold -1 | awk NF | while read one
do
  printf '%s = %04d\n' $one $(echo "ibase=16;obase=2;$one"|bc)
done

...which gives...
Code:
0 = 0000
8 = 1000
F = 1111
D = 1101
3 = 0011
0 = 0000
3 = 0011
A = 1010
2 = 0010
6 = 0110
: etc
