Xbee S2C Coordinator- Router/End Device configuration AT command mode

I have been trying to configure through AT commands two xbee S2C modules for a simple one way communication (Router/EndDevice–>Coordinator)

I had already been using xbee S2 modules for this application and it is working fine.

Now having replaced them with S2C modules ,there is no communication.

I have used the below configuration

Coordinator:

PANID = 33
DH,DL = Router’s address
CE = 1

Router:

PANID = 33
DH,DL = Coordinator’s address
CE = 0

Is there something wrong with this setting?

No, what does your AI, ID and II command report? Are they the same on both modules?
