Abstract
In a control system for peripheral devices, by operating only one device for digital-to-analogue conversion, the specific output switching corresponding to that specific device for digital-to-analogue conversion is closed and the other output switching corresponding to the other device for digital-to-analogue conversion are open so that the only the output signal of that specific device for digital-to-analogue conversion can be output. Thus, the accuracy of operation of each device for digital-to-analogue conversion can be easily evaluated.
Claims15
A control system which supplies control signals to peripheral devices for controlling said peripheral devices, comprising:
- a plurality of digital-to-analogue conversion means, each having a respective output, for receiving digital signals, for converting said digital signals to analogue signals, and for outputting said analogue signals as said control signals for controlling said peripheral devices;
- and
- output switching means connected to the outputs of said plurality of digital-to-analogue conversion means;
- wherein when only a specific digital-to-analogue conversion means is paced in an evaluating mode, an output signal of said specific digital-to-analogue conversion means is supplied to said output of said control system as an evaluation signal and output signals of the other of said digital-to-analogue conversion means are not supplied to said output of said control system.
A control system which supplies control signal to peripheral devices for controlling said peripheral devices, comprising:
- a plurality of digital-to-analogue conversion means, each having a respective output, for receiving digital signals, for converting said digital signals to analogue signals, and for outputting said analogue signals as said control signals for controlling said peripheral devices;
- and
- output switching means, connected to the outputs of said plurality of digital-to-analogue conversion means and to a processing circuit, for switching a processing circuit to an output of said control system in a normal mode of operation and for switching said digital-to-analogue conversion means to said output of said control system in an evaluating mode of operation;
- wherein when only a specific digital-to-analogue conversion means is placed in the evaluating mode, an output signal of said specific digital-to-analogue conversion means is supplied to said output of said control system as an evaluation signal and output signals of the other of said digital-to-analogue conversion means are not supplied to said output of said control system.
A control system which outputs control signals to peripheral devices for controlling said peripheral devices, comprising:
- a plurality of digital-to-analogue conversion means, each having a respective output, for receiving digital signals, for converting said digital signals to analogue signals, for converting said digital signals to analogue signals, and for outputting said analogue signals as said control signals for controlling said peripheral devices;
- and
- output switching means, connected to the outputs of said plurality of digital-to-analogue conversion means and to a processing circuit, for switching said processing circuit to an output of said control system in a normal mode of operation and for switching said digital-to-analogue conversion means to said output of said control system in an evaluating mode of operation;
- wherein said output switching means switches said output of said control system between said processing circuit in said normal mode and said digital-to-analogue conversion means in said evaluating mode based upon an input signal supplied to said control system.
A control system which supplies at least one control signal to at least one peripheral device for controlling said peripheral device, comprising:
- digital-to-analogue conversion means for receiving a digital signal and for converting said digital signal into an analogue signal;
- output switching means for receiving said analogue signal from said digital-to-analogue conversion means and a second signal from a processing means and for outputting said analogue signal to an output of said control system in an evaluating mode of operation and for outputting said second signal to said output of said control system in a normal mode of operation;
- and
- means for receiving an input signal at an input to said control system and for generating a switching control signal that is supplied to said output switching means to place said output switching means in either said normal mode or in said evaluating mode.
