4.7 Updating the System
The MW100 firmware can be updated to the latest version. The update file can be
downloaded from Yokogawa Website. Register from the address given in the MW100
Operation Guide, and download the update file.
CAUTION
• If you update the firmware, all settings such as the IP address and range
settings are reset to factory default values. Saving the current settings to the CF
card before updating the firmware makes it easy to reconfigure the MW100 after
updating the firmware.
• The IP address, subnet mask, default gateway, host name, domain name, date,
and time are not saved to the setup file. Take a note of the IP address, subnet
mask, default gateway, host name, and domain name.
• Be sure to update both the firmware and Web software. Otherwise, the operation
may become unstable.
• You may need to update the MW100 Viewer Software depending on the
firmware version (release number). For details, visit our Website or contact your
nearest Yokogawa dealer.
