Gecko firmware version 2.9 is now available for download. It brings: improved reliability to remote firmware uploads; addresses a bug in 2.8 where the “Stop Sampling” function had no effect; fixes incorrect channel labelling in Histogram and Trigger log files; and improves the STA/LTA functionality.
The upgrade process is as simple as ever – simply download the Rasbora.bin file, copy it onto your Gecko’s SD card, insert it into your Gecko and then apply power. The Gecko will use the settings file that is on the Gecko’s SD card to reapply your settings to the Gecko after the upgrade. The whole upgrade process only takes about 10 seconds.
Firmware version 2.8 was a major under-the-hood tune-up of the firmware that addresses a number of bugs and improves telemetry efficiency and MiniSEED data compatibility. You should also grab Waves 2.0 as it corrects some gain-related issues in earlier versions of Gecko firmware, and also takes advantage of new features in Gecko 2.8 data files.
Inputs versions of Gecko firmware, version 2.5 brought improved reliability for the optional Telit 3G modem. Version 2.4 introduced many new features discussed below, support for remote firmware upgrades, remote Gecko configuration via the Live Stream app and eqServer, performance improvements and bug fixes.
The Histogram feature creates a daily CSV file on the SD card, with data logged every minute. The file can be easily imported into Excel or other graphing packages. The CSV file stores the maximum and minimum signal values for each channel from the previous minute, the supply voltage, internal temperature, latitude, longitude, altitude, horizontal and vertical GPS accuracy, and the clock crystal information.
By plotting the peak signal values you can quickly visualise a day of monitoring activity, which is particularly useful for blast monitoring applications.
When a Gecko is connected to a computer running Kelunji Hub (included in the free Windows/Linux Live Stream app and on eqServer) via Ethernet connection or cellular modem, in addition to continuous data streaming we now have a “Triggered Only” mode that just sends instantaneous trigger packets, suited to EEW (earthquake early warning) applications. Kelunji Hub can immediately generate an alarm, then request waveform data from the trigger time from all connected Gecko recorders for further analysis.
You can now also save your Gecko configuration file and then load that configuration file into another Gecko, which is particularly useful when pre-configuring large numbers of identical instruments for a deployment. Don’t forget to change each station code!
