Arduino Mega, and seril port communication

by **Boneheadjoe** » Fri Oct 23, 2009 11:41 pm

Hello, I am currently looking into purchasing an Arduino Mega board for a project. For this project I must use a wireless communicator to communicate with my laptop, the wireless communicator I was given has a serial port connection. My question is can the Arduino Mega communicate through a serial connection, is that what the communication headers on the side of the board represents? thanks joe

does your device use rs-232 levels (-10-10v) or ttl (0-5v) levels. if it uses rs-232 levels you'll need something like a max-232 to do level conversions.

I am pretty sure the device uses the rs-232, since that the connection it has on it is an rs-232 connector on it. The device I am using is a connexlink 4490, with a FHSS Interface of RS-232

Boneheadjoe,
Did you get this to work?
I am currently trying to do the same thing. Mega to ConnexLink 4490. The modem is not receiving the serial print commands for some reason.
Please let me know how this project went for you.

How are you doing that? How is it connected and what code are you using? Do you have a link to the datasheet for the device you are using?
