GSM/GPRS SIM900 with arduino (Minimum System)

Hello,

I need to connect the following SIM900 with my arduino http://shop.boxtec.ch/pub/iteadstudio/GRPS_module_DS.pdf

To connect that module i think that i can do that:

P----> ?????? Rst-----> the Reset of the arduino Tx-----> the TX of the Arduino Rx------> the RX of tha arduino DT------>??????? DR------>??????? (-)------->the GND of the arduino (+)------>the 5V of the arduino

My problem is where to plug the P (Power switch pin of SIM900 module) and the DT (Debug UART data output) and the DR (Debug UART data input).

Thanks

RTFD (read the fucking datasheet), its can help you with the pin i think.

Thanks for your answer ;) i tried to understand the DataSheet but without result.

You dont have to plug the P pin to the arduino the Dt Dr pin too if i'm right its for upgrading sofware,
