7. Operation
a. Preparation
Before power up the SAM, make sure the SIM card is inserted, the antenna is connected properly
and the data cable is in place.
The default factory setting for the SAM is :
-
Terminal Data speed : 115200bps
-
Data format : 1 start bit, 8 data bits and one stop bit, no parity
-
Flow control : RTS/CTS hardware flow control
After the SAM is powered up, wait until the LED starts flashing before issuing any AT command.

Use a PC with a terminal program (like Windows HyperTerminal) to set up the SAM for a
particular application. The following AT commands can be used as a guide. For the complete set
of AT commands, refer to the AT command manual.
The AT command to the SAM always starts with AT and ends with <CR> (Carriage Return). The
response from the SAM starts and ends with <LF><CR> (LCarriage Return)
