any data acquired in the instrument will be erased to avoid inconsistencies.
To do the Upgrade:
Download the firmware that applies to your instrument.
Connect the instrument to a PC.
In the instrument software, select Configuration > Firmware Upgrade…
Browse and select the new firmware file and click ‘Open’.
If you are asked for a license key, you can find it on the flash disk that accompanied your
instrument. If you cannot locate it, contact Nortek for a new key.
Upgrade to Vectrino Plus (Vectrino only):
The Vectrino Plus firmware is protected by a license key. So the first step is to contact the local
Nortek representative to get hold of a license key.
Next:
Download the Vectrino Plus firmware from the web site.
Download the Vectrino Plus software from the web site.
Connect the instrument to a PC.
In the Vectrino Plus software, select Configuration > Firmware Upgrade…
Browse and select the new firmware file and click ‘Open’.
Add the license key when prompted.
Check that the Plus version is reported in the "Firmware" display in the software.
3.6 Erase Recorder (Vector)
Connect the instrument to a PC.
In the instrument software, select Deployment -> Erase Recorder.
Recorder wear may occur when a large number of write/erase operations are issued. The exact
number may vary between instruments but is specified to 10,000 files. This means if the recorder is
erased each time then 10,000 deployments can be done before having to replace the recorder.
The flash circuit on the main PCB is closely linked to the recorder. Read more about that here.
3.7 Update Headfile (Vector)
Most of the sensors in a Nortek instrument have to be calibrated to keep the specified accuracy.
This and the fact that we offer flexibility in probe geometry, deployment orientation and external
output/inputs make it necessary to store a number of parameters to make the instrument perform as
intended. All of this is stored in the headfile. It is actually misguiding to call it a headfile; it has
parameters that are dependent of the instruments electronics as well. We make the file when
producing the instrument, and it is saved in the respective instrument (we also keep a copy at
Nortek).
Here is a list of the calibration parameters that are stored in the headfile.
Serial no.
Pressure sensor calibration data
Tilt sensor calibration data
Beam to XYZ transformation matrix (conversion between the coordinate systems)
The transducer frequency
No. of beams
Tilt sensor orientation
Compass alignment data
Temperature sensor calibration data
Compass calibration data
The last two are dependent of the instruments electronics - not the probe head.
