Sharp MXM232DY

A. Preparation

Write the firmware (file with extension of brn) into the MX-NB12.

Necessary items for updating

• *.brn (Firmware)
• USB memory

Caution:
The firmware (*.brn) must be copied to the root directory in the USB memory in advance.

B. Updating procedures

1. Insert the USB memory into the machine.
   Caution:
   Once the USB memory is inserted, never remove it until the procedure is completed.
   The operations are enabled only when the MX-NB12 is active.
   It takes 30 seconds for the MX-NB12 from turning ON the power to activating. When turning ON the power, therefore, wait for 30 seconds before executing SIM49-02.
   Once the process is started, never disconnect the USB memory until the end of the process.
   It is allowed to save only one NNB download file (*.bm file) in the root directory of the USB memory.
2. Machine side
   Execute the service simulation No. 49-02 (Network board firmware download mode). (Check to confirm that the display below is indicated on the screen.)
3. "Download mode" is displayed on the operation panel display.
4. "Do not turn the power off." is displayed, and downloading of the firmware is started.
5. When downloading is completed, "Processing is finished. Turn off the power." is displayed.
   During execution of the simulation, do not perform a key operation of the operation panel.
6. Turn OFF the power of the machine.
7. Check to confirm that the machine is turned OFF, and remove the USB memory from the machine.
   Updating is completed with the above operation.
