EXAMPLE: Restore RF Modem Default Parameters using the Terminal tab:
Example: Both of the following examples restore the XTend Modem’s factory defaults and save
the parameters to non-volatile memory.
Method 1 (One line per command)
Issue AT Command System Response
+++ OK<CR> (Enter into AT Command Mode)
ATRE <Enter> OK<CR> (Restore modem default parameter values)
ATWR <Enter> OK<CR> (Write new values to non-volatile memory)
ATCN <Enter> OK<CR> (Exit AT Command Mode)
Method 2 (Multiple commands on one line)
Issue AT Command System Response
+++ OK<CR> (Enter into AT Command Mode)
ATRE, WR <Enter> OK<CR> (Execute multiple commands)
ATCN <Enter> 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
The ‘Modem Configuration’ tab of the X-CTU software can be used to activate advanced functions.
EXAMPLE: Read & Restore Default Parameters using the Modem Configuration tab:
The following steps show how to read currently stored modem parameter values; then restore
the modem parameters to their factory-default states.
1. Open the X-CTU program (Start --> Programs --> MaxStream --> X-CTU):
2. Under the “PC Settings” tab, select the PC Serial Com Port from the dropdown list that will be
used to connect to the RF Modem.
3. Select a "Baud rate" to match the default RF data rate of the RF Modem. Use default values
for all other fields.
4. Select the “Modem Configuration” tab.
5 Select the ‘Read’ button to read currently stored parameter values of the modem.
6. Select the ‘Restore’ button to restore factory-default parameter values.
7. Select the ‘Write’ button to save default values to non-volatile memory.
4.2.2. Binary Commands
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. RT Command must be set to ‘1’ in AT Command Mode to enable binary programming.
2. Assert CMD (Pin is driven high). (Enter Binary Command Mode)
3. Send Bytes [parameter bytes must be 2 bytes long]:
00 (Send DT (Destination Address) Command)
0D (Least significant byte)
1A (Most significant byte)
08 (Send WR (Write) Command)
4. De-assert CMD (Pin is driven low). (Exit Binary Command Mode)
Note: is high when command is being executed. Hardware flow control must be disabled as
will hold off parameter bytes.
