1. A computer-implemented method comprising:

receiving, by a primary device and a secondary device, configuration information that identifies one or more actions to be performed by the secondary device upon receipt of specified pulses of a sequence of pulses from the primary device;

transmitting, by the primary device, the sequence of pulses;

receiving, by the secondary device and from the primary device, a particular pulse of the sequence of pulses;

determining, by the secondary device, whether the particular pulse satisfies one or more predetermined criteria, comprising:

determining (i) a first time at which the pulse was received, (ii) a second time at which the secondary device predicted it would receive the pulse, and (iii) a duration between the first time and the second time;

determining, by the secondary device, that the duration is greater than a configured threshold; and

in response to determining that the duration is greater than a configured threshold:

generating, by the secondary device, an error value, and

transmitting, by the secondary device, the error value to the primary device.

in response to receiving the error value at the primary device, performing, by the primary device, a reset action.

11. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:

receiving, by a primary device and a secondary device, configuration information that identifies one or more actions to be performed by the secondary device upon receipt of specified pulses of a sequence of pulses from the primary device;

transmitting, by the primary device, the sequence of pulses;

receiving, by the secondary device and from the primary device, a particular pulse of the sequence of pulses;

determining, by the secondary device, whether the particular pulse satisfies one or more predetermined criteria, comprising:
