FCC ID: SJM-C3IW C3I-W Wireless Meter Modem

C3I-W WIRELESS MODEM INSTALLATION MANUAL THE C3IW IS A WIRELESS VERSION OF THE C3I FAMILY OF PRODUCTS WHICH IS DESIGNED TO REMOTELY READ ELECTRICAL, GAS, AND WATER METERS AS WELL AS PERFORM LOAD MANAGEMENT FUNCTIONS. THE C3IW USES TELEMETRY FREQUENCIES IN THE VHF BAND TO ACCOMPLISH THIS. THE C3IW CAN READ UP TO 4 METERS AND CONTROL UP TO 3 APLLIANCES. Load Management WHEN AN ELECTRICAL PEAK IS DETECTED AT A SUBSTATION, A DESIGNATED CODE IS SENT OUT TO A GROUP OF C3I GATEWAYS. IN TURN, THE GATEWAYS WILL SHUT OFF A DESIRED ELECTRICAL APPLIANCE FOR A SHORT PERIOD OF TIME VIA THE ONBOARD RELAY CONTROL CIRCUIT. Meter Reading THE C3I GATEWAY CAN ALSO READ DATA FROM ELECTRICAL, WATER, GAS, OR ANY OTHER TYPE OF METERING WITH CORRECT INTERFACING. WHEN METERS ARE TO BE READ, THE SPECIFIC GATEWAY WILL BE POLLED BY THE BASE UNIT, REQUESTING ITS METER READING DATA. THE GATEWAY WILL THEN SEND ITS DATA BACK IN THE FORM OF DATA PACKET. THE C3IW COMES INSTALLED IN WEATHERPROOF ENCLOSURE. T1 BAR CONNECTOR CONTAINS ALL INPUTS AND RELAY OUTPUTS ALONG WITH DC INPUT. ALL POSITIONS ARE CLEARLY MARKED FOR EASY INSTALLATION AS SHOWN BELOW:
