I have a Novatel Sa-G+ modem that i want to send data thru. Is it possible to use a Cdma modem with an arduino? I could only find info about gsm/gprs modems.
Where are the data sheets for the modem?
here is the data sheet
It looks like its a rs232 9 pin.
Can i just hook up to the rx,tx,5v,gnd pins or do i have to work with all the pins (cts rts etc ).
Thanks for the help.
It has a RS232 interface, so its easy to interface to an Arduino.
You would still need some information about what the data format the Modem requires.
The modems use AT commands but I'm not sure if i can just send it thru the rx,tx pins or if i need to send stuff to the other pins before it executes AT commands
Try sending it an "AT?", if i recall correctly, it should respond with status.

just to be sure. I only need to power the modem and hook up to the tx rx pins. I don't need to mess with any of the other pins.
If the modem uses proper RS232 signal voltages it will probably damage your Arduino. You would need a level shifter such as a MAX232 to convert to the Arduino's TTL voltages
