Abstract
A data transmission system connects a first device and a second devices, and transmits a signal therebetween. The data transmission system includes a first interface for interfacing the first device and the second device, and a second interface for interfacing the first device and the second device. The first device outputs the signal, with the signal having one of a plurality of voltage ranges. A selector selects one of the first interface and the second interface. The data transmission system also includes an indicator for indicating whether the voltage range of the signal output from the first device is out of a predetermined voltage range of the selected one interface, when the selector selects the one interface.
Claims17
A data transmission system for connecting a first device and a second device, a signal, having an operating voltage range selected from a first operating voltage range and a second operating voltage range, being exchanged between said first device and said second device, said data transmission system comprising:
- a first interface that interfaces said signal between said first device and said second device at said first operating voltage range;
- a second interface that interfaces said signal between said first device and said second device at said second operating voltage range;
- a signal transfer terminal that connects said first device with said second device for exchanging said signal between said first device and said second device;
- a selector that connects said signal transfer terminal to one of said first interface and said second interface;
- an indicator that indicates an error condition to a user of the data transmission system;
- and
- a switcher that activates said indicator using said signal exchanged between said first device and said second device, when said signal is exchanged at said second operating voltage range and said selector connects said signal transfer terminal to said first interface, wherein a voltage range of said first operating voltage range differs from a voltage range of said second operating voltage range.
A data transmission system for connecting a first device and a second device, said data transmission system comprising:
- at least two physically distinct interfaces selectively connected to said first device for receiving a signal from said first device;
- a signal transfer terminal that connects said first device to said second device for exchanging said signal between said first device and said second device;
- a selector that connects said signal transfer terminal to one of said at least two physically distinct interfaces;
- and
- an indicator that indicates, to a user of the data transmission system, an erroneous operating condition of said first device, said erroneous operating condition being included in said signal received from said first device,
- said indicator being actuated when one of said at least two physically distinct interfaces receives a signal having a voltage range greater than a predetermined range.
A data transmission system for connecting a first device and a second device, said first device outputting a signal that is inputted to said second device, said data transmission system comprising:
- a first interface that interfaces said signal between said first device and said second device at a first voltage operating range;
- a second interface, distinct from said first interface, that interfaces said first device to said second device at a second voltage operating range, said second voltage operating range differing from said first voltage operating range;
- a signal transfer terminal that connects said first device with said second device for transmitting said signal from said first device to said second device, said signal having a predetermined voltage operating range selected from said first voltage operating range and said second voltage operating range;
- means for connecting said signal transfer terminal to one of said first interface and said second interface;
- and
- an indicator that is activated to provide an indication to a user of the data transmission system when said predetermined voltage range of said signal output by said first device exceeds a predetermined input voltage operating range of said second device, said indicator indicating the existence of a voltage mismatch between said first device and said second device.
