PINK Comunication Problems (with AtomPro)

-Jp-

All,
I am currently trying to interface the PINK Parallax NetBurner (#30013) module with my AtomPro. I was able to set up and configure the module with little to no effort (via Ethernet). Then I connected it to my AtomPro and had no problems sending it commands: SEROUT TX, Baud, ["!NB0W01:",dec3 150,0]

The only thing I could never get working was the AtomPro to receive anything from the PINK module.

Below is my code (sample code):

' -----[ I/O Definitions ]-------------------------------------------------
RX CON P14 ' Serial Receive Pin --> PINK.TX
TX CON P15 ' Serial Transmit Pin --> PINK.RX
' -----[ Constants ]-------------------------------------------------------
Baud CON I2400 ' 2400 bps (BS2)
' -----[ Variables ]-------------------------------------------------------
index VAR Byte ' Index Variable
nbvar VAR Byte(16) ' PINK Data Variable Array
' -----[ Program Code ]----------------------------------------------------
Main:
SEROUT TX, Baud, ["!NB0W01:",dec3 150,0] ' Command To Read Variable 04
GOSUB ReadString ' Read PINK String Data
' serout S_OUT,i9600,[STR nbvar\15]
DEBUG [STR nbvar\15]
SEROUT TX, Baud, ["!NB0R05"] ' Command To Write Variable 05
GOSUB ReadString ' Read PINK String Data
' serout S_OUT,i9600,[STR nbvar\15]
DEBUG [STR nbvar\15]
SEROUT TX, Baud, ["!NB0R06"] ' Command To Write Variable 06
GOSUB ReadString ' Read PINK String Data
' serout S_OUT,i9600,[STR nbvar\15]
DEBUG [STR nbvar\15]
END
' -----[ Subroutines ]-----------------------------------------------------
ReadString:
nbvar=0
' SERIN RX, Baud, 100000, Timeout, [STR nbvar\20\0]' Get Data With Timeout
SEROUT TX, Baud, ["!NB0R01"]
SERIN RX, Baud,[DEC2 nbvar,STR nbvar\20\0]' Get Data With Timeout
SEROUT S_OUT,i9600, [STR nbvar\20] 
RETURN
Timeout:
DEBUG ["Communication Timeout!"] ' Serial Timeout
END

The PINK has its own power supply 5V while the AtomPro has a fresh 9V battery. I would assume everything is hooked up like it should (seeing as I am able to send commands). When I run the code in debug mode it will hang up on the "SERIN" command and never continue on (unless I add the timeout bit to it or use baud of N9600 but no data gets recieved).

Now I am able to monitor the communication via telnet and this is what I see:

Diagnostic display of Stamp to Netburner I/O
type logout to exit the monitoring session
Received from stamp:[!NB0W01:150<CLS>]
Set Var [01 to [150]]
Received from stamp:[!NB0R01]
Read Var [01] value is [150]
Send to Stamp:[150<CLS>]]
Received from stamp:[1]
Received from stamp:[5]
Received from stamp:[0]
Received from stamp:[<CLS>]

I have tried I9600 and I2400 buad rates but no success... Do I have a bad module or am I missing something? Why does it say "Received from stamp:[data]" repeated back to me?

I FINALLY GOT IT TO WORK!!! WAHOOO!
I hate when people never follow up with the solution to their problem so here it is:

I had 2 problems:
1. I am very new to micro controllers and electronics so my first problem was that I didn't ground both modules together (common ground). Rookie mistake.

AtomPro/Bot Board II ---> +/- 9v battery
PINK unit ---> +/- 5v power supply
Needed common ground between power sources.

This is the reason why it would spit out the following in the troubleshoot screen:
Received from stamp:[1]
Received from stamp:[5]
Received from stamp:[0]
Received from stamp:[<CLS>]

Once both modules shared a common ground it would only spit out one line:
Received from stamp:[150<CLS>]

2. For whatever reason I had to drop the baud rate all the way down to 2400 for my AtomPro. While Steve Norris (www.norrislabs.com) had no problem running it at 9600.

Well I hope this helps!
