Units that are to be removed from the field must be deactivated. In order to
swap out a meter, the unit must have the meter removed, be deactivated, have
the new meter connected, and then be activated.
In order to deactivate a unit, the following steps must be taken:
• The endpoint must be disconnected from the meter
• The endpoint must then be busted
Busting an endpoint forces a read of the meter. When an endpoint
unsuccessfully attempts to read a meter due to a magnet event, it will transmit
3 Magnet Packets (where the cumulative reading field is set to 0x00AAAAAA)
and deactivate. In order to activate this unit in the future, the activation
procedure described previously must be repeated. The unit will not transmit
again until it has been activated. This can be verified by busting the unit again.
The Buster will not beep/blink in response to being busted once it has been
deactivated as long as there is no register connected to the device.
NOTE: It is critical that the technician
properly deactivate the unit prior to taking it
out of service. Failure to properly deactivate
the unit will result in the transmission of data
(with the previously described timing) until
the unit’s battery life has been exceeded. This
can have detrimental effects on the CellNet
Network, particularly if the device transmits
when in a moving vehicle from different
locations.
It is important to understand that once an endpoint is activated, there may be
times when a given read of the meter is unsuccessful. This will not result in the
deactivation of the endpoint. Only an unsuccessful meter read in response to a
magnet event will deactivate the device.
