I am using a PC to transmit data using the serial port. The signals will go through a MAX232 chip before going into the RF transmitter module that i got. At the receiver module, it is connected to a PIC microcontroller.
The PIC can't seem to respond to the RF tranmission (it was ok without RF transmission)
I tested the RF transmitter and receiver using switches, LEDs and encoder / decoder chips and it was working.
Using:
Transmitter AM-RT4 https://www.electro-tech-online.com/custompdfs/2005/02/33590.pdf
Receiver AM-HRR3 **broken link removed**
So is the problem something to do with the baud rate? The transmission baud rate is currently 9600. According to the transmitter datasheet, it can only accept data rates of up to 4000Hz. The receiver can have data rate of only 2000Hz. Is this enough for a 9600 baud transmission?
