Chapter 7 Operation: C1SC Version
The SchlumbergerSema C1SC is a one-way transmitter used for fixed network
applications. The C1SC uses CellNet RF 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 assigned by SchlumbergerSema,
and programmed by SchlumbergerSema, to every meter within the network. LAN
addresses and utility billing IDs are unique to each meter. SchlumbergerSema
activates the LAN ID upon receipt of the meter association file from
SchlumbergerSema.
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.
