Human Interface Link (HIL) is a bus protocol by Hewlett-Packard for connecting various input devices to their HP 9000-series workstations. It was replaced by PS/2 in the mid-90's.

Devices can be connected in series.

The connectors are 4,6 or 8-pin SDL, with connectors keyed differently for upstream and downstream ports.

It uses 12V voltage, which is a reason why few attempts at building a converter with 5VDC microcontrollers have been attempted.
