Upgrading your Product
The Settings Page
Figure 3.1 Using the Settings Page to Select the Serial Port to be used for Product Firmware Upgrade
Current WifiTrax modules are updated using a serial interface via a USB Workshop Adapter
that you have either purchased (FWA-10, FWA-11, FWA-20) or made yourself.
Before you can upgrade the firmware on any WifiTrax product, you must select the serial port on your computer that represents this module.
To do this, connect your USB Workshop Adapter to one of your computer's USB ports, then display the Settings screen using the User, Settings menu.
On the General Settings, select the correct port in the Serial Port combo box and click Save.
On the main page, if updates are available, for your registered module, the Update F/W button will be enabled. However most people will not
want to update their module with an earlier version of the firmware than the one already installed. Therefore, the Update F/W button is not
enabled if only earlier versions, or the same version are available. Installing earlier versions is called regression and if you want to be able to
regress, or at least see the earlier versions, you can check the "Allow Regression" checkbox on the settings page.
The settings page also allows you to allow for the inclusion of beta release versions or experimental versions to be
included in the list of upgrades available. These releases may not be reliable and are there to allow some railroaders to assist
WifiTrax in evaluating new versions of software that have not yet been fully tested.
Another checkbox on the settings page disables Wi-Fi Module Scanning, so that powered-up modules are not automatically
discovered but must be entered manually. When Wi-Fi Module Scanning is disabled, the Workshop Application will remain connected to your
home network and may be more stable.
Performing an Upgrade
To perform an upgrade click the Update F/W button on the main screen.
Figure 3.2 Viewing Available Upgrades
Figure 3.2 shows the first page of the update wizard with available firmware updates listed. Select the one you want and click Next.
Figure 3.3 Downloading the Files
Figure 3.3 shows the File Download page. The files required for the firmware update are downloaded, unpacked and held in your computers memory.
They are not saved to your hard drive. When download is complete, click Next.
Figure 3.4 Preparing the Connections - an example. Different Modules have varying sets of instructions.
The next page, in figure 3.4 shows an example of the steps you must take before actually initiating the upgrade to your module's firmware. Read them carefully and click each
checkbox as you complete it. Steps listed will vary according to the type of module being upgraded. The manner in which the Workshop
Interface Module is connected to the module being updated will also vary. For example, Interface Modules with grabber leads have connections
as below. Be sure to connect the grabber leads onto the correct holes in your module:
Black Lead - GND
Yellow Lead - TXD
Orange Lead - RXD
White Lead - /PGM
On no account connect any other leads, such as power, to these points or the module is likely to be destroyed.
Other modules use JST or other types of connectors which can only be inserted the correct way.
When these steps are complete, click Next.
Figure 3.5 The Upgrade Taking Place
The update of the firmware now proceeds automatically. Do not interrupt the process, disconnect power or touch any of the leads until this screen shows complete.
If the firmware update process is interrupted, the module will be rendered completely inoperable. However if such a disaster does happen, you can repeat the upgrade process
but the module will no longer be detected by Wi-Fi until the firmware update process completes correctly.
Once the upgrade is complete, click Next.
Figure 3.6 Preparing the Module for Restart - an example. Different modules will require varying steps listed.
The next page, figure 3.6, provides a checklist of steps to return the module to its normal state.
Carefully follow the instructions, clicking each checkbox as you go. Some updates may require a factory reset and a button is enabled when necessary. A power cycle may also be required.
When all is complete, click Done.
The update wizard closes and the main page returns. After a while, which may be several minutes, the information for the selected module should show the new
You can now exit from WifiTrax Workshop and return your module to normal usage.
