Home sensors are highly recommended on all shutter axis (camera, projectors, fader), and are advisable but not mandatory for translation axes (North/South, East/West, Zoom).
This diagram shows how to wire an IBM PC parallel port to an Omron OR508ND home sensor. Note that up to four home senors can be monitored by each parallel port. You can also use the Kuper Logic Connector to accept more sensor inputs.
The Omron OR508ND or equivalent microsensors are available from DigiKey 1-800-344-4539. The ordering information supplied below are DigiKey prices as of April 1995, which have probably changed by now.
Dimensions are in milimeters. 4 pin connector (OR527ND) not shown.
