DIDO Jr. Installation Manual

11 Firmware update
The internal software of DIDO Jr. (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 Jr. 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 Jr. unit to make sure
the new firmware is compatible with the hardware revision. Some features may not work depending on
DIDO Jr. 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 Jr. (such as C:\DIDO).

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.
