64 CENTRON® Meter Technical Reference Guide
RF Options
As an option the C12.19 D/T/L register can be ordered with R300CD/CD3 functionality.
The R300CD/CD3 continuously transmits Standard Consumption Messages (SCM) and
Interval Data Messaging (IDM) using radio frequency in the unlicensed frequency band
which can be read by handheld, drive-by, or fixed network systems.
The table below describes the various versions of the RF option:
R300CD 04 N/A Two ERT register without IDM
R300CD3 08 24 Three ERT register with IDM
The transmission frequencies, the frequency hopping pattern, and the time interval between
transmission cycles are random in nature; thus providing a method for avoiding interference
with transmission from other devices.
Each SCM message contains tamper information. Below is a chart that indicates the tamper
information available in each SCM:
1 1 Meter Inversion
1 2 Meter Removal
2 1 Demand Reset (Push Button)
2 2 Low Battery or End of Billing Schedule
(1 year from end of warning)
3 1 Billing Events
3 2 Non-Billing Warnings
Tamper, Event, and Alarms Indicator Behavior: Two bits are used to log the above
alarm, event, and tamper occurrence Groups.
All Indicators are "Non-Latching", meaning the R300CD/CD3 board continues to
increment for each and every alarm, event, or tamper occurrence each time they happen.
