VBOX 3iSL User GuidePage 15 of 4901/12/2011ButtonsVBOX 3iSL has two membrane buttons on the front panel, LOG and FUNC. LOG is used to start and stop logging to the compact flash card, and FUNC is used toswitch between two sample rates, 100Hz and 20Hz.LOGThe LOG button will override any of the automatic logging thresholds set in the VBOX. For example, if you have set the VBOX to log all the time, the LOG button willtoggle logging on and off. If you have set the VBOX to ‟log only when moving‟ and you are moving, pressing the LOG button will stop the VBOX logging and closethe file on the compact flash. Logging will now not continue even if you are moving until the LOG button is pressed again or the compact flash card is removed andreinserted. The VBOX will then continue to log only when moving.Every time the logging is toggled with the LOG button, a new file is created.When the VBOX is logging, the blue CF light flashes.Do not remove the CF card or power down whilst this LED is flashing, if you need to remove the card or power down whilst the CF light is flashing, thenpress the LOG button first to stop the VBOX logging.FUNCPressing the FUNC button briefly flashes the LED‟s to indicate the current sample rate. A slow flash (once per second) on all the LED‟s indicates 20Hz, and rapidflashing (5 times a second) indicates a 100Hz sample rate. A running sequence of lights indicates a sample rate other than 100Hz or 20Hz. Pressing and holding theFUNC button for 5 seconds toggles the current sample rate. The sample rate can also be set in the VBOX software.Default setupThe default factory settings are restored to the VBOX by pressing and holding the FUNC and LOG buttons for 5 seconds. This will put the VBOX 3i into the defaultfactory settings, 100Hz logging when moving, and the standard logging parameters: sats, time, latitude, longitude, velocity, heading, height, vertical velocity, andbrake trigger event time. (DGPS will be off by default.).
