A followup:

Today I received a datasheet from Philips that provides a little more
information about the PLN-2020 Twin-eye laser motion sensor.  In it is
this:
"In order to support a wide field of applications the PLN2022 twin-eye
laser sensor is equipped with a 2k random access memory (RAM) that has
to be programmed each time the sensor is powered up. As long as the
power supply remains uninterrupted, the code is kept in memory.  Philips
Laser Sensors will deliver this customer specific RAM code."

This is new in my experience.  The sensor and its necessary
factory-supplied proprietary firmware have been separated and must be
combined at each powerup by the host.  Shades of drivers, but peripheral
microcode instead.

Will our machines need to be Internet-connected soon so that our sensors
get the latest, licensed, firmware?
