Help !!! RF Transmission not working ....

[microT]

Hi ....

I am in the process to develop a wireless system and an using the following components, the details of which are as follows :

Transmitter side :

P89LV51RD2 controller - programmed to send bytes of data serially

Receiver side (using 2 controllers):

Controller 1 - P89LV51RD2 controller - programmed to receive bytes of data serially
Controller 2 - P89LV51RD2 controller - have used this second controller to work as an application controller. Data is send from the Controller 1 to this controller using parallel communication

Further, please note that I am using the following RF devices -
Transmitter - FSK TXB1
Receiver - FSK RXC1

After writing programs for all 3 controllers ... the wired communication works absolutely fine. But when i tried working the same with RF, it does not work. Also note that i have taken care of thebaud rate (2.4K) which is in the range of the used RF devices.

Please ...if anyone could help....

Thanx in advance.

Regards,
MicroT
