Riva,
Thanks for the advice on the RS323 shield. I'll give that a try. That sounds like a better approach for an Arduino rookie.

2  Using Arduino / Networking, Protocols, and Devices / Serial Communication with video codec (GB) on: November 05, 2012, 02:35:09 pm
I am trying to communicate from Arduino Uno (TTL serial) to a Tandberg video codec (C20) via RS-232 serial (12v). Using a Parallax USB232 interface I can TX/RX RS-232 serial commands from my Mac to video codec. I can also TX/RX serial commands from Mac to Arduino. Now it's time to get the Arduino Uno talking serial straight to the video codec. 

It appears that the Parallax USB232 interface is getting power from the Mac's USB port. Can I simply power the USB232 interface via its USB Pin 1 with 5v from the Uno? The Arduino Uno will be powered through the barrel jack.  Thanks.

Another point, because my "Uno" was actually connecting as a Duemilanove-ATmega328 (not an Uno) the Mac created a serial connection. I loaded the FTDI driver to support this connection.

I solved this problem by selecting a different board. I have an Uno R3 Plus. However, it is an OEM board which means different chips. I was able to get it to work by selecting the Duemilanove ATmega328. works fine now.

Nick, I didn't notice your post until I replied back to the forum. Thanks you specifically for your time and interest. You were right on the spot.  Thanks for giving a struggling newbee a shot in the arm.  Greg

OK Arduino experts I solved the problem. I'm actually using an SOEPP Uno R3 Plus. I have been trying to upload to an Uno Board. The documentation indicates that my board is using an ATmega2560 chip. I starting trying other board types and discovered that selecting the Duemilanove w/ ATmega328 made everything work. Go figure.
Thanks for your input.

Now on to programming neat stuff.

IT appears that is correct. It came from Fry's as part of an Arduino starter kit. It's an OEM board from OSEPP.
Uno R3 Plus.  Does that have a direct bearing on the process needed to communicate with the board given the open source of Arduino

Nick, thanks for the input. I assume that you did not need to install the FTDI on your Mac??
Did the Arduino board show up as "usbmodem" initially? I'm still seeing "usbserial".
I think I'll try upgrading the OS but I don't think that is the issue.

OK Mac users, let me hear your input on this one. Thanks.   smiley-grin

I've just purchased a new uno R3 and can't get the basic BLINK script to upload. I'm using IDE 1.1 on a MacBook with OS 10.6.8. I have all permissions on the Mac. I've tried new cable, loaded the FTDI ( although not needed) and still get the same error.     

Arduino sees the board. The Serial connection is listed as tty.usbserial.  Should that be tty.usbmodem ??
The board is getting power is simply fails the upload.

Any suggestions? I thought this was supposed to be easier on a Mac.

Wow, all this feedback is great. However, I still can't get my Uno R3 communicating with my Macbook running OS 10.6.8 and Arduino 1.1 . Although not needed I've loaded the FTDI driver and still "no dice"
