Abstract
To control a chemical analyzer, a program counter sequentially energizes the row conductors of a bus-bus type program card, with the columns being connected to a command interpreter prearranged to distinguish between commands not requiring a data input and commands that require a data input. Commands requiring a data input automatically permit sequencing to the next command which is a data readout while inhibiting the outputs from the conductors that provide commands for operations not requiring data such as the operations of raising and lowering pipettes or moving chemical receptacles one position. The data is read through a decoder while the sequencing is temporarily inhibited and the command outputs are inhibited. An additional command is provided by a direct signal from the program counter with no conductive connection between the rows and columns of the program card.
