How to connect EB500 bluetooth module (RX,TX) with other MCU (RX, TX)

Dear all
I just bought EB500 Embedded-Blue bluetooth module from
www.parallax.com last week.
Now I have some easy question to ask you about how to connect it to
PIC18F452 or other MCU.
1. I have to wire PIN3(RX) of EB500 to TX or RX of the PIC because in
manual states that PIN3(RX) =
UART data output, so it should be connect at RX of other MCU, is that
right? (RX to RX and TX to TX)
2. Is it possible to connect both EB500 and MAX232 simultaneously in
PIC? I did this and it seems that
EB500 doessn't response any command (it doesn't send any
acknowledge character back to my PIC)
3. Can you give me procedure to first test module or how to
communicate with module?
I did force MODE pin to low (command mode) and send printf("get
addr\r"); to EB500 but nothing's happening.
(PIC can't detect any return acknowledge characters).
4. How much delay time to put before module ready? I've never used
basic stamp before so I don't know
what PAUSE 1000 is stand for. (I guess 1000 ms, right?)
I really need your help, I'm in hurry doing this project, so It would be
kind of you if you can reply me
as fast as possible.
