4.2.2. Binary Commands
To Send Binary Commands:
Note: CTS (GPO1) is high when a command is being executed. Hardware flow control must be disabled
as CTS will hold off parameter bytes.
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)
Send AT Command
+++
ATRE <Enter>
ATWR <Enter>
ATCN <Enter>
System Response
OK <CR> (Enter into Command Mode)
OK <CR> (Restore RF modem default parameter values)
OK <CR> (Write to non-volatile memory)
OK <CR> (Exit Command Mode)
Method 2 (Multiple commands on one line)
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)
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.
1. Select the 'Read' button.
2. Select the 'Restore' button.
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)
