Chapter 7 Operation: C1SC Version
The Itron C1SC is a one-way transmitter used for the CellNet fixed network
technology. The personality module transmits a formatted data packet consisting
of the preamble, the utility billing ID, kWh information, and Cyclic Redundancy
Checks (CRC) to ensure message integrity. The module also features built in power
outage notification, reverse power flow detection, power restoration notification,
and redundant transmissions. The C1SC uses spread spectrum to broadcast its
message in the 902 to 928 MHz frequency range once every five minutes.
The C1SC is factory programmed to include the utility billing ID, LAN Address ID,
and Register configuration. The utility billing ID is a value decided upon by the
utility and CellNet. The LAN address is a value that is assigned by Itron and
programmed into every meter within the network. LAN addresses and utility billing
IDs are unique to each meter. Itron activates the LAN ID upon receipt of the meter
association file.
After programming, the module is tested to verify the operating system parameters
and FCC compliance. A final test is performed via RF to verify a correct LAN
address meter ID number of digits and RF signal.
