3.2.5. Command Mode
AT Commands
To Enter AT Command Mode:
To Send AT Commands:
To Exit AT Command Mode:
To modify or read modem parameters, the modem must first enter into Command Mode, the
state in which incoming characters are interpreted as commands. Two command types are
available for programming the modem:
For modified parameter values to persist in the modem registry, changes must be saved to non-
volatile memory using WR (Write) Command. Otherwise, parameters are restored to previously
saved values when the modem is powered off and then on again.

Default AT Command Mode Sequence (for transition to Command Mode):
Send AT commands and parameters using the syntax shown below:
Figure 3.9. Syntax for sending AT Commands
The preceding example would change the modem Destination Address to “1F”. To store the new
value to non-volatile (long term) memory, the Write (ATWR) Command must follow.
System Response. When a command is sent to the modem, the modem will parse and execute
the command. Upon successful execution of a command, the modem returns an “OK” message. If
execution of a command results in an error, the modem returns an “ERROR” message.

For examples that illustrate the steps of programming the modem using AT Commands, refer to
the RF Modem Configuration [p21] chapter.
NOTE: To read a parameter value stored in a register, leave the parameter field blank.
• AT Commands
• Binary Commands
• No characters sent for one second [refer to the BT (Guard Time Before) Command]
• Input three plus characters (“+++”) within one second [refer to the CC (Command
• No characters sent for one second [refer to the AT (Guard Time After) Command.]
Send the 3-character command sequence “+++” and observe guard times before and after
the command characters. [Refer to the “Default AT Command Mode Sequence” below.] The
“Terminal” tab (or other serial communications software) of the X-CTU Software can be used
to enter the sequence.
