Updating the DSIU’s Firmware

1. Check Program 90-17-15 in the Aspire programming to

confirm the firmware version of the DSIU PCB.

2. Download the firmware update files and SIO application

from the NEC Technical Support web site.

3. Unzip the SIO application (WinZip application required

4. Copy the FLASH.KTB and FLASH2.KTB files into the

same directory as the SIO application.

5. Move the RUN/BLOCK switch to the BLOCK position.
6. Remove the DSIU from the system cabinet and position

the Application jumper located at the

top

Next, update the CPU firmware using the following steps:
1. Rename the FLASH.KTB file to FLASH1.KTB. Rename

FLASH2.KB to FLASH.KTB.

2. Remove the DIN connector from the DSIU PCB.
3. Remove the DSIU from the system cabinet.
4. Move the jumper on the upper connection back to its original position (placed on

only one pin).

5. Position the CPU jumper located at the

bottom

of the PCB to closed (place the

jumper over both pins to connect them).

When the second file is done:
1. Remove the DIN cable.
2. Remove the DSIU from the system cabinet.
3. Move the jumper on the lower connection back to its original position (placed on

only one pin).

4. Re-install the DSIU PCB into the system cabinet.
