3.3 MEASURES PAGE
The "measures" page provides the detail of the product technical information.
3.3.1 GENERAL DETAILS
Provides detailed information of internal power supplies voltages / fan currents / temperature.
Figures are displayed in purple if all is OK and become red if the value is out of range (in this example the
camera module is not plugged on the basestation so its parameters are null displayed in red).
3.3.2 OPTICAL DETAILS
These two groups monitor the basestation and the camera unit optical state.
Each figure will change color if the alarm threshold is reached (60mA for the laser , < -18dBm for the 3G
optical receivers and < -13dBm for the 12G optical receivers).
The optical level below -18dBm (-13dBm) warns the user against a too high fiber attenuation or a dirty
connection, it does not mean that the signal will be lost (each receiver is tested to -20dBm(-15dBm)) but that
a connector cleaning or fiber trouble shoot has to be done on an asap basis.
The laser overcurrent is a preventive information, it indicates something wrong and that the unit need
service asap but should be still able to transmit data for the current event.
