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 10 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 (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.
Command reference table
This AT command information is provided for reference. For additional details, refer to the XTend and XTend vB RF
module user's guides.
XTend Commands
(The RF modems expect numerical values in hexadecimal. Hexadecimal values are designated by
a “0x” prefix. Decimal equivalents are designated by a “d” suffix.)
