two hex FF characters and one hex 20 character. This tells the motor that it is the end of the
file and to revert to regular command mode.
Details on the downloadable file:
When you compile an SMS file with the SMI software, it creates an SMX file extension with the
same name in the same directory. That is the file you need to download to the motor.
Perform the following steps to complete the download operation:
1.
Establish serial communications with the motor.
2.
Issue the LOAD command.
3.
If ECHO is enabled, you should see the LOAD command followed by an ECHOed hex 20.
4.
Hex value 06 should be transmitted by the motor. Read and verify this byte.
5.
Transmit the first 32 characters from the SMX file. If the SMX file is shorter than 32
bytes, just send what is available and skip to step 8 (sending FFFF 20).
6.
Hex value 06 should be transmitted by the motor. Read and verify this byte.
7.
Repeat step 5 using the next 32 bytes.
8.
When the last character is read from the file and sent to the motor, then send two hex
FF characters and one hex 20 character to the motor.
9.
Issue another RCKS command. If it returns a success status (with the P character at the
end), then the download was successful.
10.
RUN the program (no reboot required).
The following are reasons for unsuccessful download:
l
Noise on the serial port
l
Loss of connection during download
l
Failure to send the two hex FF characters and one hex 20 character before power down
l
The SMI-compiled SMX file was altered in some way
NOTE: Do not alter the SMX file from its originally-compiled version. For example,
if you open an SMX file in Windows Notepad to view and save it, Notepad
automatically adds a carriage return character to the end of each line. Therefore,
the saved file will not work, and the carriage returns must be removed before
downloading the file to the motor.
