Claims

[Scope of utility model registration request]

In a telemeter device that transmits data and makes calls between one master station and multiple slave stations using a wired polling digital transmission method, the master station connects the transmission path of each slave station individually or commonly through a call switching circuit. a detection circuit for detecting a tone signal of a call request from the slave station side, and receiving the output of this detection circuit to notify the call request from the slave station side, and switching the call switching circuit to the call circuit side. It includes a call switching control means for forming a communication path, and a call requesting means for requesting a call by simultaneously sending a tone signal in a frequency band different from that of the data transmission to the transmission path corresponding to each slave station. The telemeter device is characterized in that the telemeter device is equipped with a call requesting means for transmitting a tone signal in a frequency band different from that for the data transmission to a transmission line corresponding to each slave station.
