Pulse counter registers

Gen 4 bridges (and above) support two pulse inputs. The bridge counts the pulses on each of the
inputs and provides this data in the registers.
Note: The bridge counts both rising and falling edges of the pulse. These registers store the total
count. This value is persistent even after bridge reset.

Sensor Calibration keys

Each Panoramic sensor is calibrated during manufacturing and a unique calibration key is
generated for every sensor. This key is used to calibrate the sensor raw measurements to achieve
optimal accuracy.
When working in PowerRadar mode, raw measurements are calibrated in the cloud. In stand-alone
mode, however, the calibration is done on the bridge itself, utilizing a unique calibration key.
The calibration key is a sensor specific, 15 alpha-numeric string (e.g. ACD43-XU3V5-Z7RF3), which
must be provided when allocating a sensor to be used in stand-alone mode and dual mode.
To get a calibration key for a specific sensor use one of the flowing options:
•
Automatically calibration key retrieval - if the laptop used to configure the bridge has
Internet access, a calibration key can be automatically retrieved when defining the sensor
in the bridge. This is the easiest and most efficient way to get the calibration key. Internet
access is only required for the laptop used to set the bridge and only during the
configuration.
•
Manual calibration key retrieval – In the rare case where internet access is not available
during bridge configuration, please contact
serial numbers of sensors needed. A file containing the respective calibration keys will be
provided to be manually entered into the bridge.
Meaning
This slot has no sensor S/N allocation. All other registers in
this slot can be ignored.
A sensor S/N has been assigned to this slot, but no sensor
message has been received since the last bridge reset. This
can be because the sensor is not yet installed, is not in the
bridge RF coverage area or because the device monitored by
the sensor is off.
All other registers in this slot can be ignored.
A sensor S/N has been assigned to this slot, and a reading has
been received. The reading timestamp, Current value and
RSSI can be processed.
A sensor S/N has been assigned to this slot, and a reading has
been received. However, since the bridge has no real-time-
clock (RTC) the timestamp value is 0. In this case the Bridge
RTC clock should be set via the Bridge Date/Time settings
register.
