Abstract
A remote meter reading system (10) includes a group of meter interface units operable in an inactive state and periodically activated to monitor a communication channel for activity. Each meter interface unit (12) is responsive to communication signals from a meter reading device (15). The meter reading device (15) initiates communication with a first meter interface unit (12) selected from the group. The meter reading device (15) transmits to the first meter interface unit, a first message including a request for data. The meter reading device (15) then receives transmissions from the first meter interface unit (12) which are governed by a first transmission rule. The meter reading device (15) determines when at least a second meter interface unit (12) is operating in an active state, and transmits to the first meter interface unit (12), a second message including a specifier for a second transmission rule.
