WRITING VNP1 FIRMWARE
Firmware is written on the VNP1, which is an Ethernet controller. If the fi rmware is not written, the Ethernet cannot be used.
Once the fi rmware is written, it is not necessary to write it again. It is automatically detected if the writing is necessary during
start-up and the fi rmware is automatically written if necessary.
1. Timing for writing VNP1 fi rmware
Firmware is written on the VNP1 in the following cases:
• If no fi rmware is written on the VNP1
When the power to the VNP1 is turned on for the fi rst time at the time of the production, the VNP1 has no fi rmware
and fi rmware is written on the VNP1 without exception.
• If the program section is updated
New VNP1 fi rmware is contained in the program section. If the updating of the program section causes the necessity
of updating VNP1 fi rmware, fi rmware will be written on the VNP1.
2. Execution and confi rmation
• If no fi rmware is written on the VNP1
Turn on the power. It is automatically judged if fi rmware should be written on the VNP1 and the writing will be started
automatically if necessary.
• If the program section is updated
Completion of the program section updating is followed by automatic restart. (All LEDs will light for about 0.5 second.)
Then, it is automatically judged if fi rmware should be written on the VNP1 and writing will be started automatically if
necessary. If there is no necessity of writing, startup is not accompanied by writing fi rmware.
∗ The PEAK LEDs fl ash alternately during writing. It takes about 1 minute for writing. Do not turn off the power during
writing. When the PEAK LEDs stop fl ashing, the writing is completed. The Ethernet can now be used.
