Serial Status Input Circuit

When collecting status input data, a few points rapidly consume many connections requiring distribution panels, multiplex logic and expensive parallel IO devices. This simple serial circuit allows you to daisy chain status inputs up to 16 inputs using only four wires. I chose this circuit for a Subsea System due to the high cost of underwater cabling and connectors.
