GAPS - User Guide
10.2 Maintenance from the Web-Based User Interface
You have access to a series of maintenance tasks from the Web-Based user interface
maintenance button. These tasks are:
● Calibrating the GAPS after removing a whole arm or an hydrophone
● Updating the system
● Checking the options that are currently installed
● Resetting to factory settings
● Contacting iXblue technical support
10.2.1 CALIBRATING THE GAPS ACOUSTIC ANTENNA
Important
If one or several hydrophones have been replaced by other ones, your GAPSantenna needs
to be calibrated again. Please refer to the maintenance user guide for complete details on the
calibration procedure.
10.2.2 UPDATING THE SYSTEM
iXblue sends to you an update file when available. The update file names have:
● “.srec” or “.sre” extension
● “TQ_” prefix for the mother board
● “G4W_” for the signal processing board
Upload this file from your computer directly into GAPS via the procedure below. In case of two
successive updates, you may reboot GAPS between the updates.
ZIP the update files when mailing them to avoid file corruption caused by mail applications.
UNZIP update files received by mail before loading them into GAPS.
If both TQ and G4W firmware have to be updated: make sure that you download the
Gen4Ways (G4W) firmware before the PowerPC (TQ) firmware into GAPS.
Save your current configuration before performing the update.
