16-bit Network Address (my) need to be same in both modules. why your setting DL of coordinator is MY of router i didn't get it? and what is mean by 9F0,ABCD
for simple 2 way communication just set the same pan id for the both modules and first configure the coordinator and next set the router.
if your going with point point communication set
coordinator DH=router 1st 8 bit mac(13A200)
Dl=router 2nd 8bit mac(example:xxxxxx)
same in router DH=coordinator 1st 8 bit mac(13a200)
DL=coordinator 1st 8 bit mac(xxxxxx)
it will work fine try this one
