Before you start

  • 32-bit Windows XP, Vista or 7.
  • An existing, working Seletek/Armadillo installation.
  • Armadillo owners: the miniUSB cable included with the device.

Step 1—firmware migration tool

Download and install the firmware migration tool—custom made to assist in migrating from 1.x to 2.0 firmware versions—then disconnect external power from the controller, which will now be powered from the USB alone. Armadillo owners: connect via the miniUSB connector behind the "Firmware upgrade" sticker, beside the power supply connector. Launch the guided updater program to install the new bootloader.

Please note: there is no settings migrating tool, so if you want your settings preserved, write them down before you start and set them up again once everything is done. It should take about a minute—or see save all Seletek settings to a file.

Step 2—install the new software

Uninstall the previous software (from the Control Panel, or using the shortcut in the start menu under Seletek), then install the new version—this part works on any Windows XP or later system. Then download the firmware file matching your device type from the Seletek downloads page and save it somewhere convenient; the desktop is such a location.

If you are using the Armadillo, going back to the "normal" USB is strongly recommended at this point, so store the miniUSB cable somewhere convenient—most probably you will not need it again.

Step 3—load the firmware

Launch the new Seletek program (Start menu, Seletek, then Seletek), power the controller with its usual power supply (normally +12 V DC), and plug in the USB cable—the big USB cable, for any controller. Then just drag and drop the firmware file onto the Armadillo image you can see in the upper left of the window. The firmware load starts straight away; wait a moment and it is done.

As in previous versions, and in order not to fill up your ASCOM menus, you have to run each application you want available from ASCOM manually once—run "Focuser" a single time and it will be available from ASCOM from then on.

Success indicator: after a successful update, the controller's LED flash pattern changes to half-second off, then a fast blink, and again.

Troubleshooting

  • The program can't launch your browser: download the ATMEL tool manually instead.
  • The controller resets during the update: use a shorter, thicker USB cable to prevent power-draw issues while the flash memory is being written.

If the firmware upgrade fails: use the firmware recovery procedure to flash it manually.
