9XTend ‐ PKG ‐ E? ? Ethernet ? RF ? Modem ? – ? Product ? Manual ? v2.x4x ? [2007.01.04]
4.1.2. AT Command Examples
Terminal Tab (X-CTU Software)
A terminal program has been built into the X-CTU software and is located under the 'Terminal' tab.
The Terminal tab provides an easy-to-use interface for programming the modem.
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.
Restore RF Modem Default Parameters (Using the ‘Terminal’ tab of the X-CTU Software)
Example: Both of the following examples restore the XTend Modem's factory defaults and save
the parameters to non-volatile memory.
Note: ?? Do ? not ? send ? com ‐
Method 1 (One line per command)

Send AT Command
+++
ATRE, WR <Enter>
ATCN <Enter>
System Response
OK <CR> (Enter into Command Mode)
OK <CR> (Execute multiple commands)
OK (Exit AT Command Mode)
NOTE: ? Default ? parameter ? values ? of ? the ? RF ? Modem ? can ? also ? be ? restored ? by ? selecting ? the ?? Restore ?? button ? located ?
on ? the ? “Modem ? Configuration” ? tab ? [refer ? to ? the ? example ? below].
Modem Configuration Tab
Sample Configuration: Restore RF Modem Defaults
Example: Utilize the X-CTU “Modem Configuration” tab to restore default parameter values.
After establishing a connection between the modem and a PC [refer to the 'Setup' section
above], select the “Modem Configuration” tab of the X-CTU Software.

Select the 'Read' button.
Select the 'Restore' button.
4.1.3. Binary Command Example
To Send Binary Commands:
Example: Use binary commands to change the RF modem's destination address to 0x1A0D and
save the new address to non-volatile memory.
1.
2.
3.
4.
RT Command must be set to '1' in AT Command Mode to enable binary programming.
Assert CMD (Pin 10 is driven high). (Enter Binary Command Mode)
Send Bytes [parameter bytes must be 2 bytes long]:
00 (Send DT (Destination Address) Command)
0D (Least significant byte of parameter bytes)
1A (Most significant byte of parameter bytes)
08 (Send WR (Write) Command)
De-assert CMD (GPI1 is driven low). (Exit Binary Command Mode)
Note: CTS (GPO1) is high when a command is being executed. Hardware flow control must be disabled
as CTS will hold off parameter bytes.
