6 SETUP AND INSTALLATION
6.6.1 Performing a PICOSCALE firmware update
Firmware updates are files named like "picoscale-1.0.1__2015-12-01_160436.fw". The file
must be copied to a USB memory stick, which has to be plugged into one of the
PICOSCALE
USB ports. For reducing problems, the stick should be empty (possibly freshly formatted) before
copying the new firmware to it.
Before starting the update process, the PICOSCALE has to be switched off. Hold the pilot laser
button and switch the device on, by pushing the power button. Do not release the pilot laser
button until it starts blinking, which indicates that the device is in the update or reconfiguration
mode.
NOTICE
It is important that the update process is NOT INTERRUPTED by switching off
the power supply. Otherwise the device may become unresponsive and must be
sent in for repair!
The update process may take a few minutes (5-15). When it has finished, the device will be in its
normal operation mode and the pilot laser button should have stopped blinking.
NOTICE
In rare cases the update procedure does not finish after a few minutes. This
problem may occur when updating PICOSCALE Controllers with an installed
firmware version older than v1.1. If the pilot laser button does still blink af-
ter 30 minutes, please switch the device off and on. The device will continue its
firmware update. During this phase, as described above, it must not be switched
off. Now, the update should finish after a few minutes.
Some firmware updates may also require an update of the programming interface libraries (SDK)
and the software tools for the
PICOSCALE.
6.6.2 System diagnostics data
The PICOSCALE interferometer allows saving system diagnostics data (to a USB stick) for analysis
of problems. To save diagnostics data, start the device and plug in a USB memory stick. Wait until
it has booted and entered the normal operation mode. Hold the pilot laser button until it starts
blinking (this should happen after at most 10 to 15 seconds).
NOTICE
It is important, that the device is in normal operation mode, before the pilot
laser button is pressed!
