EX1200 Series Maintenance 133
NOTES 1) The instrument password uses lower-case letters.
2) This password mechanism provides only the most basic security. Applications requiring
additional security should consider using private, dedicated subnets, firewalls, etc. to
limit access to the instrument on the network.
UPGRADE
This action page is used to upgrade the embedded firmware of the EX1200 controller and DMM
(if installed) as well as the plug-in modules. Prior to initiating the firmware upgrade process, a
new, uncompressed firmware image must be obtained from VTI Instruments and be accessible
from the computer that is connected to the EX1200. Unless specifically noted by VTI Instruments,
firmware upgrades do not alter the non-volatile configuration settings (network configuration, time
configuration) of the EX1200.
NOTE Do not power cycle the EX1200 during the firmware upgrade process. If power is lost during the
upgrade, the instrument may be put into an inoperable state, requiring return to the factory. An
uninterruptible power supply may be used to avoid this risk.
FIGURE 7-22: UPGRADE WEB PAGE
Perform the following steps to conduct a firmware upgrade:
1) Remove Temporary Internet Files.
2) Perform a Reboot or a power cycle.
3) Connect to the EX1200 via the embedded web page.
4) Click on the Upgrade link.
5) Click on the Browse button and select the firmware image file to be uploaded to the
instrument.
6) Click the Submit button to initiate the upgrade process.
During the firmware upgrade, an Upgrade Status window will appear (see Figure 7-23). Note
that, if a DMM is not installed in the system, one fewer step be reported. Controller/DMM
firmware upgrades typically take about 5 minutes to complete. Upon completion of the upgrade,
click on the Reboot button. After rebooting has completed (approximately one minute), click on
the Index link in the Command Menu to continue operating the EX1200 using the web interface.
Note that the “Rebooting” prompt will not refresh itself.
