Sending data packet from Tx to Rx - Rx can't see packet??

What steps will reproduce the problem?
1.Using X-CTU set Rx parameters as follows (My:02, DH:0, DL:01)
2.Using X-CTU set Tx parameters as follows (My:01, DH:0, DL:02)
3.Enable API mode = 1
4.Upload the two sketches I have attached.

What is the expected output? What do you see instead?
I expect to see the data packet 'hi' in the serial monitor on the Rx side.

What version of the product are you using? On what operating system?
Xbee Series one 

Please provide any additional information below.
See attached screen shots of serial monitor for Tx and Rx. 
Also see attached code for Tx and Rx. 
The code to see the data packet doesnt get reached. This tells me the data 
packet hasn't arrived in the Rx??
