4 MAINTENANCE
4.1 USB installation for the MAESTRO
The MAESTRO has a USB type mini B port. When connected to a PC it emulates a standard serial port.
This means that it is possible to connect many MAESTROs on one computer, without tying up the
ordinary serial ports, while keeping a simple interface that is easy to design software for. The MAESTRO
can function using the USB port power only. It does not utilize the battery energy when it is linked to a
computer through the USB port.
4.2 Free Software Upgrade
Keep up to date with the latest versions of MAESTRO software including new features and options. As
new and improved versions of the device's firmware are created, it is in your best interest to update your
MAESTRO. The latest device firmware can be downloaded from the Gentec-EO website.
Access our website at www.gentec-eo.com . Go to the Downloads section. Find the file that corresponds
to your MAESTRO in the Downloads section and follow our simple, easy to use instructions.
In summary you will download a .BIN file that you will have to copy to a USB key. Remove any old .bin
files on the USB key. Insert the USB key and touch the update button in the about menu. This should
take a few minutes; after which you will need to turn off and restart the MAESTRO.
4.3 Battery Charging
As mentioned previously, the MAESTRO meter is operated using four standard rechargeable Ni-MH
batteries. When the low battery window pops up, recharge the batteries by connecting the external
power supply for four hours. The MAESTRO can be either on or off during this procedure. One battery
charge provides up to 6.5 hours of operation autonomy.
The MAESTRO may not function properly when the battery level is very low. In which case, connect the
power supply to the MAESTRO to recharge the battery.
You can operate the MAESTRO by plugging it into a USB port when the battery is low, or even removed,
but it will not charge. Charging requires the external power supply.
4.4 Troubleshooting
If your MAESTRO does not turn on or off, remove all power supplies including the battery, and reconnect
them.
Measuring all energy points.
For Energy acquisition of 100Hz and higher, use the full size real time display to log data on the USB key,
the graphic display needs a lot of computing and you may lose some points, do not surf in other menus or
resize the display, avoid using the PC-MAESTRO.
When using the external trigger, avoid sending voltage pulses while the MAESTRO boots up as it may
hang (cause the MAESTRO to crash) the MAESTRO. Contact Gentec-EO for a special external trigger
cable if this solution is not acceptable.
