Firmware update
The internal software of DIDO LT (the firmware) can be updated. This is necessary since new FW will
correct bugs from previous versions or add new functionalities. The serial port of the DIDO LT must be
connected to the RS-232 (“COM”) port of a PC-compatible personal computer, running MS-Windows 98,
2000, or XP operating systems. Make certain to set the baud rate to 115k, unit address to 0, and back up
the settings before updating firmware. Always check the serial number on the DIDO LT unit to make sure
the new firmware is compatible with the hardware revision. Some features may not work depending on
DIDO LT model, which is determined by the four digit batch number (example: bbbb-SNxxxx with
“bbbb” representing the batch number).
Update procedure
•
Create a directory for the DIDO LT (such as C:\DIDO).
•
Save the attached files to the created directory.
•
Unzip the files if necessary.
•
Open a Win32 (Command Prompt) window (Start
Æ
Run
Æ
cmd
Æ
Enter).
•
Change to DIDO LT directory (C:\DIDO).
•
Type this command “DIDOldr.exe 1 DIDO.did” and press “Enter.” (Note: To change the COM
port use the appropriate comm. port number in place of the 1)
•
It will take approximately 20 seconds to finish programming and the device will restart itself. If
it does not restart, unplug the power and re-apply it after 5 seconds.
•
Under System Settings select Default Settings and confirm.
Important: avoid programming the DIDO LT using USB-RS232 adapter since it may not work
properly.
