ABSTRACT:
A number of remote terminals are connected to various utility meters to store the readings therein. A central terminal sequentially transmits signals to the remote terminals to actuate the same to transmit the meter readings to the central terminal. Each remote terminal comprises storage units to store the readings of the meters respectively. Each storage unit is designed to store the number of digits required for the meter reading, and also a code digit which indicates the type of meter (gas, electric, etc.) or instructions (skip to next meter, remote terminal address, user number, etc.). The code digit is transmitted as if it were a part of the meter reading. A connector card is insertable into a receptacle to detachably set the codes into the storage units of the remote terminals.
