Abstract
A first device receives a bit sequence from a second device via a serial communication cable having one or more wires that connect the first device to a first set of one or more pins of a first chip of the second device. The first chip has a second set of pins. For each respective pin of the second set of pins, the bit sequence includes a set of one or more bits for the respective pin that are based at least in part on whether a first voltage or a second voltage is applied to the respective pin. The first device determines, based on the bit sequence, a type of the second device.
