Abstract:
Apparatus for remote reading successive data of various devices wherein a common line connected to a recorder joins the data sources of sub-units to successively transfer data to the common line, a signal being transmitted at the end of each reading to switch to the next sub-unit so that all the data are successively recorded. Each sub-unit comprises registers with means to register the data, a motor for driving a member analyzing the registering means, both of them being connected to a common line and driving the switching elements, a transfer line for connecting a succeeding register after a work cycle and a recorder being connected to the common line to record the successive data.
