4.1.2. AT Command Examples

Send AT Commands (Using the X-CTU Terminal Tab):

After following the steps outlined in the Configuration Setup section [previous page], the RF

modem is ready to be programmed. The following steps utilize the Terminal tab of the X-CTU

Software to read and write parameter values.

1. Highlight the Com Port from the ‘Select Com Port’ list that is mapped to the Ethernet RF

Modem.

2. Select the Terminal tab; then enter the following characters:

Sent AT Command System Response

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

ATDT <Enter> 0 <CR> (Read Current destination address)

ATDT1A0D <Enter> OK <CR> (Change destination address to 0x1A0D)

ATWR <Enter> OK <CR> (Write new value to non-volatile memory)

ATCN <Enter> OK <CR> (Exit AT Command Mode)

NOTE: Multiple commands can be sent on one command line. The following command line entries

will yield the same results as above. Commands must be separated by a comma (“,”).

Sent AT Command System Response

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

ATDT <Enter> 0 <CR> (Read Current destination address)

ATDT1A0D, WR, CN <Enter> OK <CR> (Execute multiple commands)

Both of the preceding examples change the RF modem destination address. If the RF modem is

to communicate with other RF modems, their destination addresses must match.

Send AT Commands (Using the X-CTU Modem Configuration Tab):

After following the steps outlined in the Configuration Setup section [previous page], the RF

modem is ready to be programmed. The following steps utilize the Modem Configuration tab of

the X-CTU Software to read currently stored parameter values; then restore the modem

parameters to their factory-default states.

1. Highlight the Com Port from the ‘Select Com Port’ list that is mapped to the Ethernet RF

Modem.

2. Select the Modem Configuration tab.

3. Select the ‘Read’ button. (Currently stored parameter values are displayed.)

4. Select the ‘Restore’ button. (Original default parameter values are restored and written to

the RF modem’s non-volatile memory.)

4.1.3. Binary Command 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)
