remote controlled car

Hi, I have few questions.
I’m doing my final year project. I have a car which have receiver http://www.abacom-tech.com/assets/data_sheets/RTF_L-DATA-SAWuser.pdf and PIC16f877 http://ww1.microchip.com/downloads/en/devicedoc/30292c.pdf .
This car is controlled wireless with another pic16f877 and another RTF-DATA-SAW.
So, questions:
1. Can I connect pic16f877’s tx directly to “tx data input” pin of transceiver, and pic’s rx pin directly to “rx digital out” pin or transceiver? Or do I need some level converters like MAX232? (Im talking about both, the receiver part and transmitter part)
2. Does this transceiver (RTF-DATA-SAW) encodes data to Manchester, or I need to do this in my code? (mikroC)
3. Maybe anyone have some examples of mikroC code? (I just only need to light led on car with pushbutton from remote control)

p.s. I have real schematic (not in Proteus or etc.)
thanks in advance

Can i see your real schematic...? pleace.....

Receiver: Microcontroller Pic16f877, Led (portB pin 0) and rtf-data-saw
Transmitter: mc pic16f877, pushbutton (portB pin 0) and rtf-data-saw
just it.

OK, it's brow-beatin' time!

Final year project and you don't know how to lookup (or read) a datasheet?!?

The RTF-DATA_SAW datasheet was easy to find via Google [HLMGTFY]:

* http://www.abacom-tech.com/assets/data_sheets/RTF_L-DATA-SAWuser.pdf

And, just a cursory look indicates logic-level TX input and there's a section on Manchester (don't know if that means there is an encoder in the device-didn't spend a lot of time on details [YOUR JOB!] (e.g. RTFDS!)

Also, how about you at least attempt to write your MikroC code and if it doesn't work, post it and we'll have a look-see.

In other words, i'm happy to help, but I'd rather not do all the work for you (I'm a busy guy -- especially since your credentials indicate that you are capable (or at least should be).
