EXAMPLE: Restore RF Modem Defaults using the Terminal tab

The following steps show how to read currently stored modem parameter values; then restore

the modem parameters to their factory-default states.

Method 1 (One line per command)

Issue AT Command System Response

+++ OK<CR> (Enter into AT Command Mode)

ATHP <Enter> (system shows current channel number) <CR>

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>

ATRE, WR, CN <Enter> OK<CR>

NOTE: Default parameter values of the RF modem can also be restored by selecting the “Restore

Defaults” button located on the Modem Configuration tab [refer to the instructions below].

Modem Configuration tab

The “Modem Configuration” tab of the X-CTU software provides an easy-to-use interface for

reading and setting RF modem parameters.

EXAMPLE: Read Parameters & Restore Defaults 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 (long-term) memory.

4.2.2. Binary Commands

Example: Send Binary Commands

Example: Use binary commands to change the XStream 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 of parameter bytes)

1A (Most significant byte of parameter bytes)

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.
