9XCite™ OEM RF Module – Product Manual v2.1 [2007.01.04]
2.2.5. Command Mode
AT Command Mode
AT Command Mode provides access to AT-Settable parameters. These parameters extend flexibil-
ity in configuring modems to fit specific design criteria such as networking modems. Not all of the
parameters in the XCite Module can be adjusted using AT Commands.
To Enter AT Command Mode:
Default AT Command Mode Sequence (for transition to Command Mode):
All of the parameter values in the sequence can be modified to reflect user preferences.
To Send AT Commands:
Figure 2‐08. Syntax for sending AT Commands
To read a parameter value stored in the module register, leave the parameter field blank.
The preceding example would change the module’s Destination Address to "0x1F". To store the
new value to non-volatile (long term) memory, the Write (ATWR) command must subsequently be
sent before powering off the module.
System Response. When a command is sent to the module, the module will parse and execute
the command. Upon successful execution of a command, the module returns an “OK” message. If
execution of a command results in an error, the module returns an “ERROR” message.
To Exit AT Command Mode:
For an example of programming the RF module using AT Commands and descriptions of each config-
urable parameter, refer to the "RF Module Configuration" chapter.

• No characters sent for one second [refer to the BT (Guard Time Before) Command]
• Input three plus characters (“+++”) within one second
• No characters sent for one second [refer to the AT (Guard Time After) Command.]
[refer to the CC (Command Sequence Character) Command.]
Send the 3-character command sequence "+++" and observe guard times before and after
the command characters. [refer to ‘Default AT Command Mode Sequence’ below.] The ‘Ter-
minal’ tab (or other serial communications software) of the X-CTU Software can be used to
enter the sequence.
[OR]
Assert (low) the CONFIG pin and turn the power going to the RF modem off and back on. To
achieve this result, simultaneously press the Reset and Config switches [Figure 1-02];
release the Reset Switch; then after 1 second, release the Config Switch. The RF Modem
then enters AT Command Mode at the modem's default baud rate
If no valid AT Commands are received within the time specified by CT (Command Mode
Timeout) Command, the module automatically returns to Idle Mode.
Send ATCN (Exit Command Mode) Command.
[OR]
