Abstract
A device receives an analog voltage signal over a single physical electrical connection. The analog voltage signal can be converted into a digital value which can then be correlated to (i) an indication of a connection state of the primary device, and (ii) information about another device (or set of devices) which is connected to the device.
Claims17
A first device, comprising:
- a connector element to receive a physical electrical connection from a respective connector element of a second device if the second device is connected to the first device;
- an analog-to-digital converter to convert an analog voltage signal received on the connector element to a digital value;
- and
- logic resources to process the digital value to determine (i) a connection state, from a plurality of connection states for the connector element and (ii) preselected information of the second device, the preselected information including a revision identifier of the second device and a category of the second device.

A module device, comprising:
- a module connector element to receive a physical electrical connection from a primary connector element of a primary device if the primary device is connected to the module device;
- and
- a voltage divider component to receive a voltage reference and to provide an analog voltage signal on a voltage detection line using the module connector element, wherein the voltage divider component is to generate the analog voltage signal to correspond to a preselected value that is correlative to a revision identifier of the module device and a category of the module device.
A device assembly, comprising:
- a first device connected to a second device by a voltage detection line, the first device comprising:
- an analog-to-digital converter to convert an analog voltage signal of the voltage detection line to a digital value;
- and
- logic resources to correlate the digital value to a preselected information of the second device;
- wherein the second device comprises:
- a voltage divider component to output the analog voltage signal on the voltage detection line using a reference voltage, the voltage divider component being preselected to correlate to the preselected information of the second device, and
- wherein the preselected information includes a revision identifier of the second device and a category of the second device.
