2.2.5. Command Mode
To modify or read module parameters, the module must first enter into Command Mode (a state
in which incoming characters are interpreted as commands). Two command types are supported:
"   AT Commands
"   Binary Commands
AT Commands
To Enter AT Command Mode:
1.   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.
 
[OR]
2.   Assert (low) the
 pin and either turn the power going to the module off and back on.
(If using a MaxStream XIB-R Interface Board, the same result can be achieved by keeping
the configuration switch pressed while turning off, then on again the power supplying the
module assembly (module assembly = module mounted to an interface board))
Default AT Command Mode Sequence (for transitioning to Command Mode):
"   No characters sent for one second [BT (Guard Time Before) parameter = 0x0A]
"   Input three plus characters (+++) within one second [CC (Command Sequence Character)
Command = 0x2B-0]
"   No characters sent for one second [AT (Guard Time After) parameter = 0x0A]
To Send AT Commands:
Send AT commands and parameters using the syntax shown below.

The preceding example would change the module Destination Address to 0x1F. For modified
parameter values to persist in the module registry, changes must be saved to non-volatile
memory using WR (Write) Command. Otherwise, parameters are restored to previously saved
values after the module is powered off and then on again.
NOTE: To read the current value of a module parameter, leave the parameter field blank. For
example, the following command will return the current destination address: ATDT
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:
1.   Send ATCN (Exit Command Mode) Command.
 
[OR]
2.   If no valid AT Commands are received within the time specified by CT (Command Mode
Timeout) Command, the Module automatically returns to Idle Mode.
For an example that illustrates programming the module using AT Commands, refer to the
Module Configuration chapter [p18].
