is very important to use the latest GT-11 firmware. Both features
and performance are significantly enhanced by the firmware upgrade.
Please don't complain about lack of features or performance if
you do not use the latest firmware. GT-11 firmware develops very
rapidly (daily). Test versions work very well and improve steadily.
Remember that we TEST the firmware under development. Please report
any strange behavior here.
1. Download the latest software
a) firmware (1115.rar
b) NaviLink (both Command line AND Windows) from Locosys
c) Firmware Update software (NAViFu.exe)
2. If you don't have WinRar, download
WinRAR 3.70 or later, install it, and recover files from *.rar
archives downloaded in step 1. If you downoaded the ZIP file above,
you need to "unzip" the content.
3. Install both NaviLink programs and Firmware
Update (NAViFU.exe) software.
4. Plug the Navi USB cable and connect the Navi/GT11
to it. Make sure that this connection will not be interrupted
during the firmware update.
5. Turn on Navi/GT11. If your current firmware
is 1024f or higher, as indicated by SETTINGS>VERSION you need
to enter the UPDATE mode: SETTINGS>VERSION>UPDATE>YES
6. Exit all other Windows applications, finish
printing etc. When Windows monster runs out of resources (for
whatever reasons) it may interrupt the firmware upload, in which
case you will need to send your Navi for service to revive it.
A simple precaution of terminating other programs during firmware
upgrade greatly increases the reliability of the process.
7. Run NAViFU.exe program and select the COM port from
the pop-up menu.
8 . Select Browse in NAViFU program and choose the Navi_fw.s
firmware file that you downloaded in step 1a and recovered in
9 . Choose "execute". Navi light should flash
and progress bar should be displayed on PC.
10. After the execution is complete, power your Navi-GT11
down and up again. Go to Settings and select Version. You should
see the Version Number corresponding to the name of the file in
step 1a. Rename Navi_fw.s file to include the
Version number. For example if you updated to 1115 rename the
file to Navi_fw1115.s . This will help you to
keep track of your updates.
